Wireless sensor networks are multi-hop randomly distributed networks which collect environmental data and send them to some sink nodes. These networks are different from other wireless networks in several aspects; most distinct one is vital effect of power limitations there. This limitation means they must be in sleep mode as much as possible. In this paper, the authors propose an algorithm for topology control in these networks. This algorithm is distributed, power efficient and fair, which means power consumption in the network is spread among all nodes instead of a few ones. Performance simplicity is other advantage of the algorithm. A discussion on other methods for comparison is also provided.
