The Coverage Controllable Mechanism (CCM): An Energy Conservation Method for Wireless Sensor Networks

摘要

Recently, wireless sensor networks, which are composed of advanced MEMS (Micro Electro Mechanical Systems) called sensor nodes, have been broadly researched as ad-hoc networks, Since sensor nodes are powered by limited-life batteries and are usually deployed in difficult environments, they need to be able to conserve their power consumption as well as guarantee broad coverage and connectivity. On most occasions, a variable but full coverage is required. In this paper, we focus on the coverage controllability and propose a simple self-controlling method for sensor nodes that is based on a probing mechanism, Only local information about the nodes' operation status is necessary to ensure the desired coverage of the entire wireless sensor networks.
