Abstract

To satisfy the coverage requirements in wireless sensor networks (WSNs), redundant sensors are usually deployed, which may cause unnecessary energy consumption on sensor nodes. To address this challenge, we propose a novel distributed rotation-based coverage (RBC) control strategy for heterogeneous sensor networks. This strategy only need to analyse a few special points' coverage to determine each sensor node's working schedule, and thus can significantly reduce the complexity of coverage computation. Theoretical analysis and simulation results show that the proposed coverage control algorithm and protocol can outperform prior work in terms of not only the energy saving but also the energy balancing.
