Coverage Control Algorithm for Node Scheduling in Wireless Sensor Networks

A large number of wireless sensor nodes (SNs) are usually deployed in a remote area, where these nodes accurately monitor the environment and communicate the data collected by the SNs, to a central processing station wirelessly. Since the SNs are powered by batteries, therefore, to prolong the network operating life, they must utilize energy efficiently. In this paper, we propose a method to control scheduling of the SNs in an area to prolong the network life. Probabilistic detection model forms the basis for coverage control algorithm (CCA) in a wireless sensor network (WSN). In this model, each sensor node is assumed to detect an event occurring within its sensing range, with a certain probability. Finally, the effectiveness of this algorithm is verified by comparing it to other algorithms in a simulated experiment.
