Cooperative data censoring for energy-efficient communications in Sensor Networks

Signal processing algorithms in Wireless Sensor Networks claim for energy efficiency because of node energy scarcity. Tailored to this scenario, in this paper we develop energy-efficient cooperative strategies for selective communications. Cooperation among nodes is exploited in order to optimize energy consumption while guaranteeing good overall performance. The analysis of representative scenarios reveals that cooperative selective nodes yield a good performance in both network lifetime and quality of the transmitted information under different network conditions.
