Efficient Gatherings in Wireless Sensor Networks Using Distributed Computation of Connected Dominating Sets

Abstract : In this paper, we are interested in enhancing lifetime of wireless sensor networks trying to collect data from all the nodes to a "sink"-node for non-safety critical applications. Connected Dominating Sets are used as a basis for routing messages to the sink. We present a simple distributed algorithm, which computes several CDS trying to distribute the consumption of energy over all the nodes of the network. The simulations show a significant improvement of the network lifetime.
