Abstract:
An ever-growing demand for pervasive Internet access has boosted the deployment of wireless local networks in the past decades. Nevertheless, wireless technologies face performance limitations due to unstable propagation conditions and mobility of devices. In face of multi-path propagation and low data rate stations, cooperative relaying promises gains in performance and reliability. However, cooperation procedures are unstable (dependency upon current channel conditions) and introduce overhead that can endanger performance, especially when nodes are mobile. In this paper we describe a novel protocol, called RelaySpot, able to implement cooperative relaying in dynamic networks, based upon opportunistic relay selection, and cooperative relay scheduling and switching. RelaySpot removes the need for estimation and broadcast of channel conditions, and is expected to improve the utilization of spatial diversity, minimizing outage and increasing the transmission capacity of wireless local networks.
