CCSL: A Connected Coverage Strategy Based on Logistic Layers in Wireless Sensor Networks

This paper mainly studies the problem of connected coverage control in wireless sensor networks and proposes a strategy called CCSL (connected coverage strategy based on logistic layers) based on the relationship of coverage and connectivity. The strategy adopts the logistic layers to solve coverage and connectivity problems independently. By doing this, CCSL can achieve the optimization of both connectivity and coverage. What's more, CCSL uses a "tree cutting" arithmetic to induce the redundancy nodes and save energy. Our research about connected coverage problem includes not only the specific algorithm of CCSL but also a framework of protocol easily extended. Experimental results show that CCSL can reduce the energy consumption by turning off the connectivity redundancy nodes and coverage redundancy nodes, so it prolongs the network lifetime effectively.
