Cooperative communication strategies for sensor networks

This paper focuses on a relay-based sensor network where there is no direct link between the sensing elements and the destination, with a cluster-head acting as the relaying element. The destination in this scenario may be another cluster-head or the ultimate receiving-station. Our goal is to enable cooperative communication in such a scenario, allowing the nodes in the cluster-head to work cooperatively amongst them. We find this enablement problem to be a minmax optimization problem whose solution is at the intersection of two capacity regions
