Abstract

Enhancing sensor network lifetime is an important research topic for wireless sensor networks. In this paper, we introduce a solution for prolonging the lifetime of sensor networks that is based on a deployment strategy. In our proposal, data traffic is directed away from the network center toward the network peripheral where sinks would be initially deployed. Sinks stay stationary while collecting the data reports that travel over the network perimeter toward them. Eventually perimeter nodes would be exposed to a peeling phenomenonwhich results in partitioning one or more sinks from their one-hop neighbors. The partitioned sinks move discrete steps following the direction of the progressive peeling. The mechanism maintains the network connectivity and delays the occurrence of partition. The performance of the proposed protocol is evaluated using intensive simulations. The results show the efficiency (in terms of both reliability and connectivity) of our deployment strategy with the associated data collection protocol.
