Performance analysis of an Adaptive Relay Selection protocol for energy constrained networks
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 8
Abstract
Relay selection is crucial in improving the performance of wireless cooperative networks. Most of current works related to relay selection algorithms in cooperative communications use the Channel State Information (CSI) to decide whether to use one or another neighbor as a relay. Motivated by the benefits of cooperative relaying we explored an idea of adaptive relay selection scheme which selects the relay based on CSI and the energy remaining in the nodes. In this paper, we propose a cooperative multihop routing for the purpose of energy savings i.e.,if a node is centrally located and has that dispose of the best channels to its neighbors in a given network, it will be continuously sought to relay its neighbor’s packets, in addition to its own traffic. Consequently the battery of this node will be quickly empty and the network can be divided into two disjointed parts. System outage probability, energy at nodes and average bit error rate (BER) are analyzed.
