Minimization of power consumption is a critical design goal for wireless-relay networks comprised of battery powered sensor devices. Traditionally, wireless communication is optimized to minimize the total transmission power. In the paper, the authors further include the detection power and the reception power in order to minimize the overall network power consumption for information exchange in Wireless-relay Sensor Networks (WSNs). Specifically, after the physical attributes of relay nodes are given, they wish to maximize the network lifetime by a proper selection of the transmission range, the sleep period, and the participation density. They propose a Random Gossip Network (RGN) as a framework for their analysis.
