Abstract:

In this paper, we develop novel algorithms to find the optimal, energy preserving, paths from Source Node (SN) to the Base Station (BS) in Wireless Sensor Networks (WSNs). Optimality is defined in a constrained sense, in which the minimal energy route is sought (to maximize the lifespan of WSNs) under reliability constraint, meaning that each packet must reach the BS with a given probability. Energy efficiency is going to be achieved by selecting nodes for multi-hop packet forwarding under information, which yields the most evenly distributed energy state over the network after the packet has reached the BS. There are many efficient protocols which increase the lifetime of sensor network such as LEACH, PEGASIS, and PEDAP. But they failed to provide energy balancing under reliability constraints. Solving this problem, we propose a new algorithm under name High Quality of service Routing Algorithm (HQRA), which is able to find near-optimal paths in WSNs by minimizing the energy but guaranteeing a given level of reliability, as well. New High Quality of Service Routing Algorithm for WSNs, which finds the minimum energy path from the SN to the BS and achieves a predefined level of reliability. The proposed method can run in polynomial complexity, with respect to the number of nodes, by recursively using the Bellman-Ford algorithm. Furthermore, HQRA gave good results with any BS positioning in wireless sensor network. The simulation results will demonstrate that our algorithm is more efficient than the other routing protocols proposed before.

Abstract:

This paper attempts to apply cooperative relay in an underlay wireless cognitive radio network, where all of the secondary user nodes draw their power from a primary user within a certain threshold level in order not to interfere with it. The network is divided into pairs, and each pair is assumed to have synchronized exchange-relay ability, i.e. performing data transmission and providing an alternative path to the direct link of the other pair. The simulation results prove that enabling relay technique gives significant enhancements to the system\\\'s performance through decreasing the outage probability. Furthermore, the efficiency has been improved by inviting all the nodes to participate in providing multiple paths to exchange data, which in turn gives a robust cognitive radio network.

Abstract:

According to eMarketer market research, smartphone users will be reached 2 billion in 2016, resulting in a lot of challenges for current cellular networks, such as bandwidth utilization, spectrum crisis and high energy consumption. Although the fourth generation (4G) networks are now becoming great success, it cannot accommodate the challenges. Device-To-Device (D2D) communication may be one of key solutions for the next generation (5G) networks to deal with these issues. D2D communication in cellular networks allows direct communication between two mobile users without assisted from Base Station (BS) or infrastructure based networks. With initial studies, the D2D communication exposes some advantages for improving spectrum efficiency, communication delay, as well as energy consumption; however, it still has some shortcomings, such as security issues, mobility management, and handoff. The research community is now actively contributing for the next generation networks by adopting the D2D communication. This presentation will focus on discussing about the challenges, designs, and future research directions of D2D communication in 5G cellular networks.

Abstract:

In OFDM, multiplexing over MIMO channels or general trans-multiplexing techniques a number of independent sub-carriers or sub-channels arise for transmission, which differ in SNR. Maximizing the channel capacity or data throughput under the constraint of limited transmit power leads to the well-known and simple water-filling algorithm. However, the performance of water-filling algorithm is generally degraded by the bit-loading following it. Alternatively, incremental bit-loading can optimize the data rate if greedy power allocation is considered. The problem of the greedy algorithm is its associated computation complexity bottleneck which prevents its use in many recent wireless applications. The focus of this presentation will be the simplified state-of-the-art greedy-based power allocation techniques. This presentation will provide novel computationally efficient sub-optimal greedy-based power allocation algorithms to maximize data rate of multicarrier systems. Moreover, mean BER enhancement of the resulting bit-loading can be achieved by considering residual power redistributions which aim to relate rate maximization in conjunction with margin maximization design problems. The evaluation will include analysis, simulation, and discussions of the results.

Abstract:

Multicore architectures suffer from high core-to-core communication latency due to the traditional wire based network and power-hungry cache’s unpredictable behavior. As the number of cores increases, managing the requests from many cores and satisfying the large number of requests as quickly as possible becomes a critical challenge. Studies suggest that a directory with the information about Level-1 Cache (CL1) blocks can be helpful in order to reduce the communication latency. The recently introduced wireless router in network-on-a-chip shows promise by efficiently handling many requests, simultaneously, faster and cheaper (consuming less energy). Therefore, we introduce a Level-2 Cache Mediator (L2CM) and a hybrid network (with wired and wireless routers) into a multicore/many-core system to improve system scalability. The proposed L2CM should have enough memory to store information about CL1 cached blocks, CL1 victim blocks, etc., and a wireless router for low-power fast communication with Central Processing Unit (CPU) cores. According to the experimental results, (considering communication delay and power consumption) the proposed architecture is better than mesh multicasting for all cases and is better than or as good as wireless network-on-a-chip. Experimental results suggest that the proposed L2CM may decrease the communication delay by up to 63% and the total power consumption by up to 33%.

Abstract:

A multidisciplinary research effort focusing on secure wireless communication networks, motivated by the fact that the solutions to next-generation communications networks lie in a multidisciplinary research approach formed by electromagnetics, micro systems, digital signal processing, error control coding, cryptography , physics and information theory, is presented. For example chaos theory was originally developed by mathematicians and physicists. The theory deals with the behaviors of nonlinear dynamic systems. Therefore, and based on chaos theory features, the security research community adopts chaos theory in modern secure wireless communication networks. However, there are challenges of using chaos theory with secure communication. Also the multidisciplinary nature of the research in the field of Quantum Key Distribution Networks (QKDNs). Such networks consist of a number of nodes that can perform security protocols protected by some basic laws of physics. The operation of QKDNs mainly requires the integration of Quantum Key Distribution (QKD) protocols with the already-existing network security infrastructures.

Abstract:

Wireless transmission in the lower microwave band is congested by applications such as Wi-Fi, GSM, etc. Some other new wireless technologies (e.g., WiMAX) are still handled within the lower microwave regions (2–5 GHz). Therefore, unlicensed 60 GHz frequency band (57–64 GHz) and 70-94 GHz band have been considered in the last few years. In the United States, the 60 GHz band can be used for unlicensed short range data links. Propagation characteristics of the 60 GHz band like oxygen absorption and rain attenuation limit the range of communications systems which use this band. Also, geographical consideration is crucial for antenna Base Stations (BSs) installments. Because of large number of required BSs and the high throughput of each BS, deployment of an optical fiber backbone is necessary. Therefore, hybrid systems are considered to support the intense demand of high quality telecommunications services. Fiber backbone network is widely considered to support usage of unlicensed 60 GHz band. This network provides a broadband link between central office (CO) and BSs. This hybrid network can decrease the complexity and cost of the BSs by moving the routing, switching and processing functionalities to the CO. This way, the equipment cost can be shared among antenna BSs. Optical modulators such as Mach–Zehnder modulators (MZMs) can be utilized to generate optical millimeter wave signals. The lecture presents an overview of the photonic generation of millimeter wave signals for wireless applications. Different modulation methods are discussed and the performance analysis of transmission links is presented.

Abstract:

The use of multiple antennas at both the transmitter and receiver aims to improve performance or to increase symbol rate of systems, but it usually requires higher implementation complexity. The antenna spacing must be larger than the coherence distance to ensure independent fading across different antennas. Alternatively, uncorrelated signals in different antennas can be assured through the use of orthogonal polarizations. Multiple Input Multiple Output (MIMO) architectures can be used for combined transmit and receive diversity, for the parallel transmission of data or spatial multiplexing. When used for spatial multiplexing, MIMO technology promises high bit rates in a narrow bandwidth. Therefore, it is of high significance to the spectrum users. In this case, MIMO system considers the transmission of different signals from each transmit element so that the receiving antenna array receives a superposition of all transmitted signals. All new ideas about how to improve performance, capacity and/or spectrum efficiency while keeping computational cost at an acceptable level have been described. Multi-user MIMO (MU-MIMO) has also been introduced, where multiple streams of data are simultaneously allocated to different users, using the same frequency bands. This concept is similar to Space Division Multiple Access (SDMA). Nevertheless, while SDMA is typically employed in the uplink, MU-MIMO is widely used in the downlink. MU-MIMO presents several constraints, as downlink channel state information is required at the base station side (transmitter), and the processing is implemented using pre-coding (instead of the conventional post-processing approach). Ideas and concepts on MIMO applications, such as base station cooperation, coordinated multi-point transmission or multi-hop relay are also described. These are effective mechanisms that improve the performance at the cell edge, while mitigating the negative effects of near-far problem and adjacent cell interference, resulting in a more homogenous service quality, regardless the users\\\' positions. These concepts can be viewed as special types of MIMO systems, but where the different transmit or receive antennas are not collocated, but positioned in different locations. It is known that around 50% of the operational costs associated to cellular communications rely on the energy consumption, which also has an implication in the carbon emission footprint. MIMO Systems and Applications can contribute to the concept of Green Radio Communications, while supporting a reduction in the energy consumption. This presentation will provide a technical assessment of each of the technologies associated to MIMO systems and applications, while indicating the constraints associated to each one.

Abstract:

Divisible Load Theory (DLT) merged as a very efficient tool to schedule arbitrarily divisible load on a set of network processors. Most of previous work using DLT assumes that the processors\\\' speed and links\\\' speed are time invariant. Closed time solution was derived for the system based on that the speed of processors and links stay the same during the task execution time. This assumption is not practical as most of the wireless connected processing elements used today have an autonomous control. In this paper we consider distributed wireless systemswhere the availability of the processors varies and it is following a certain distribution function. A closed form solution for the finish time is derived. The solution considers all system parameters such as the links\\\' speed, number of processors, number of resource, and availability of the processors and how much of their power they can contribute. The result of is shown and it measures the variation of execution time against the availability of processors.

Abstract:

This talk will present our recent research in the area of synthesis, RF characterization, strategic design, and employment of functional nanomaterials for a wide variety of RF/MW/THz devices. Magneto-dielectric and high-k dielectric nanocomposites have been developed as a new class of materials well-suited for electromagnetic wave devices. In particular, magnetic/dielectric nanoparticles have been synthesized and evenly dispersed in a host polymer matrix to tailor its effective microwave properties, thus improving antenna performance (i.e., size, gain, bandwidth, efficiency). The RF properties, including permittivity, permeability, dielectric and magnetic loss tangents, were extracted over a wide frequency range (0.1-20 GHz), while monitoring the effects of the nanofillers reinforcement and externally applied magnetic field.The magneto-dielectric Fe3O4-PDMS composites have been incorporated into miniaturized multilayer patch antennas with center frequency of 4 GHz that exhibited 58% of bandwidth enhancement and 57% of size reduction. Meanwhile, the effects of the sintering and other processes were rigorously studied that has led to improved dielectric and loss properties. Specifically, PDMS nanocomposites with sintered NdTiO3 fillers have exhibited a high permittivity (r~12) and loss tangent (tanδd<0.01) at frequencies up to 17 GHz on par with the loss of the typical PCBs. This new class low-loss nanocomposite is an enabler for the next generation of RF/MW/THz devices. A 3D multi-material additive manufacturing process is going to be employed to produce miniaturized 3D conformal microwave components. The talk will be concluded with a brief discussion of other ongoing activities, which focus on development of transmission-line based microwave devices and millimeter wave dielectric waveguides, etc.

Abstract:

In many rural areas of developing countries, there are no telecommunications services or are very limited. This is particularly severe in remote areas of very low density or high population dispersion. This condition has more serious implications in areas such as health or education and obviously, without access to telecommunications infrastructure, it is impossible to use the ICT tools currently available or perform other administrative activities or professional development. These rural areas, where the digital divide is wider, are not attractive to carriers or service providers, so it is expected that a significant number of them do not enjoy data transmission services in the medium term. In this perspective, the possibility of deploying community networks or private networks is at least interesting and perhaps achievable, especially for rural public institutions. Nevertheless, the sustainability of these networks and services represent the main problem to be faced, with many seemingly successful experiences which then, have shown that were not sustainable. This presentation, based on the experience gained by the Rural Telecommunications Group of PUCP in the implementation of various ICT projects in some of the most difficult and remote rural regions of Peru, will describe the different solutions implemented to ensure the sustainability of wireless telecommunications networks have been installed in the framework of these projects, then, will make a critical analysis of them, in light of its current status and results and finally will propose a generic scheme under which focus sustainability assurance, in the context of ICT development initiatives.

Abstract:

Emerging applications based on the IoT are introducing new security challenges. They operate in a dynamic environment dominated by the evolution of the security threats and the variation of network features (e.g., network topology, energy level). One of the major challenges that should be tackled is the trade-off between robustness and energy-efficiency. This strengthens the need for in-network processing such as aggregation and compression to limit the computational, memory, and storage overhead. Existing cryptographic algorithms and protocols are not compliant with such processing and turn out to affect the lifetime the mobile nodes being part of the IoT. To cope with this problem, homomorphic encryption is introduced in this talk as an alternative to improve the applicability cryptographic solutions to IoT-based applications. Concrete examples are described and analyzed in order to illustrate the potential brought by homomorphic encryption in providing energy-effective protection of the IoT.

Abstract:

The integration of physical systems with networked sensing, computation networks, and embedded control with actuation has led to the emergence of a new generation of engineered systems, the Cyber-Physical Systems (CPS). Such systems emphasize the link between cyber space and physical environment (i.e., time, space, and energy). CPS represents the next generation of complex engineering systems. They are large scale dynamic systems that offer significant processing power while interacting across communication networks. CPS will help to solve the grand challenges of our society, such as, aging population, limited resources, sustainability, environment, mobility, security, health care, etc. Applications of CPS cover a wide band of economic, medical, and entertainment sectors. It includes; Transportation: automobiles, avionics, unmanned vehicles and smart roads; Large Scale Critical Infrastructure: bridges, mega buildings, power grid, defense systems; Health Care: medical devices, health management networks, telemedicine; Consumer Electronics: video games, audio/video processing, and mobile communication. Building Cyber-Physical Systems is not a trivial task. The difficulty arises from the existing gap in modeling and computing of the physical and cyber environments. The design process require new theories, models, and algorithms that unify both environments in one framework. None of the current state-of-the art methods are able to overcome the challenges of developing the unified CPS design paradigm. Several of these issues will be discussed in this talk. Case studies of real world CPSs will be illustrated.

Abstract:

Broadcasting is a fundamental operation in wireless networks and plays an important role in the communication protocol design. Wireless transmissions are unreliable; it is possible for packets to be lost due to interference, transmission errors or collisions. Such losses reduce the delivery ratio (number of nodes that receive the broadcast message). The loss rate can be considerable if high interference exists or if link quality is low. In this presentation, we address the problem of reliable broadcasting in spite of collisions and transmission losses. The aim is not to achieve reliable broadcast to all nodes in the network; rather, the aim is to ensure reliable broadcast to a desired percentage of nodes. We present a geometric based, probabilistic model to predict the optimal transmission range for maximizing 1-hop broadcast coverage in wireless networks as a function of range, sending rate and density. We demonstrate how the adaptation techniques can be incorporated into different broadcasting protocols.

Abstract:

The wireless channel suffers from attenuation and multipath fading, which result from multipath transmission, and also from propagation effects, that include reflection, diffraction and scattering. Multipath fading is a major cause of performance degradation in mobile communications systems. Modulation diversity is a bandwidth-efficient diversity technique that consists of the rotation of a digital signal constellation, associated with the interleaving between the in-phase and quadrature components. It is intended to reduce the effects of fading in wireless communications. In this presentation a scenario is considered in which multiple paths are simulated, with associated random multiplicative noise and delay. The evaluation of the multipath fading effect in this scenario is done by comparing BER values for 4-PSK and 8-PSK transmissions, to obtain the gain provided by the modulation diversity. An analysis of the optimum rotation angle is provided, which consider several multipath scenarios, and include cases with a more severe fading effect.
