A Coverage-Preserving Density Control Algorithm Based-on Cooperation in Wireless Sensor Networks*

摘要：

Node density control is one of the most important measures to save energy consumption in large Wireless Sensor Networks (WSNs), and it aims to minimize the number of on-duty nodes when maintaining the original network coverage. In this paper, CPSBC, a coveragepreserving self-scheduling protocol is proposed. CPSBC is based on a new sensing model--Cooperative Sensing Model (CSM) other than traditional Boolean Sensing Model (BSM), and multi-sensors’ cooperative exploration is considered in it. With CPSBC, sensor nodes that have minimum contribution on coverage and satisfy Coverage Preserving Rule meanwhile will be scheduled to fall in asleep in each round. It has been verified by simulation that CPSBC can keep the original network coverage with less on-duty nodes than BSM mechanisms, thus results in higher energy efficiency.
