Opportunistic Routing in Wireless Multi-hop Networks

Azzedine Boukerche and Amir Darehshoorzadeh

thAbstract: Opportunistic Routing (OR) is a new promising paradigm, which has been proposed as a way to increase the performance of wireless networks by exploiting its broadcast nature. It benefits from the broadcast characteristic of wireless mediums to improve the network performance. In OR, instead of pre-selecting a single specific node to be the next-hop as a forwarder for a packet, multiple nodes can potentially be selected as the next-hop forwarder. Hence, each node in OR can use different potential paths to send packets toward the destination.  More specially, when the current node transmits a packet, all the candidates that receive the packet successfully will coordinate with each other to determine which one would actually forward the packet according to some criteria, while the other nodes will simply discard it.

The proposed tutorial is intended to offer a comprehensive state-of-the-art survey on OR research. We will explain the fundamental idea of OR and its important issues by providing some examples. We will then categorize each of the important issues and explain them in detail. We will explain different OR metrics in addition to the different way of candidate selection using some example. Furthermore, we will illustrate different protocols from each category and compare their benefits and drawbacks. The tutorial will be continued by describing some important analytical aspects in OR with emphasizing  on the performance analysis of OR using a Discrete Time Markov Chain (DTMC) paradigm. During the tutorial we will use some simulation and numerical results to support different ideas and aspects of OR. Finally, tutorial will be concluded with a comprehensive review of open research challenges and some potential directions for future research in OR, thus making the material presented in this tutorial useful for researchers and academics.

Energy Efficiency in Wireless Networks

Fabrizio Granelli and Marco Di Renzo

Abstract: With the increasing growth of wireless access to the Internet and its services, wireless networks represent a key communication infrastructure for ubiquitous connectivity. The need to support exponential growth in data traffic as wellas availability of several mobile devices (smartphones, tablets, etc.) is leading to a sharp increase in the number of base station devices and in their complexity, leading to a consequent increase in power usage and consumption. Indeed, high power consumption can represent a limiting factor for the scalability of next generation wireless networks.

The tutorial will first present an overview of power consumption in wireless networks, aimed at identifying the major sources of power consumption and to define proper benchmarks for performance evaluation. Based on such analysis, different architectural and technological solutions will be proposed in order to reduce or optimize energy consumption in wireless networks. Based on the reference heterogeneous scenario of coexisting 3G LTE macro/pico/femto base stations, relay terminals, WiFi WLANs, etc. the tutorial will survey the relevant solutions at the PHY, MAC and network level, as well as advanced paradigms related to cooperation, network coding and cognition. All major solutions will be analyzed and compared by offering the unique vision provided by the EU funded GREENET project, with detailed simulations as well as real testbed experiments.
