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:

Despite the large variety of existing communication systems, each development has been motivated by the same goal: to provide universal service facilities to users, while maintaining or increasing profitability. Interoperable, ubiquitous and dynamic are key objectives for fifth-generation (5G) communication systems and applications. WISDOM is a vision of for a global 5G wireless communication system realized by universally deployable converging technologies to enable personalized wireless services and applications at a data rate of more than one terabit per second (Tbit/s), with coverage extending from a city, to a country, to the continents and to the world, that will enable user-centric mega-communications. This talk will discuss the technical challenges to realizing WISDOM as well as the WISDOM enabling potential to deal with the complexity of the emerging user expectations for novel personalized usage scenarios bringing about a myriad of high-quality services not for the mere sake of transmitting data but for enabling the virtualization of the reality of the human emotions, senses, and feelings. WISDOM is a wireless system that allows to establish and maintain ubiquitous human bonds and not merely wireless connections. This talk explores novel boundaries for next generation human-bond communication systems and outlines the major technological challenges.

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.
