RelaySpot: A Framework for Opportunistic Cooperative Relaying

Advances in wireless technologies, including more powerful devices and low cost radio technologies, have potential to drive a ubiquitous utilization of Internet services. Nevertheless wireless technologies face performance limitations due to unstable wireless 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 (rely on current channel conditions) and introduce overhead that can endanger performance especially when nodes are mobile. In this paper, the authors describe a framework, called RelaySpot, to implement cooperative wireless solutions in large mobile networks, based upon the combination of opportunistic and cooperative methods.
