An Energy Efficient Coverage Method for Clustered Wireless Sensor Networks

Free registration required

Executive Summary

An important issue in WSN is the regional covering. A coverage algorithm should be able to solve this issue by considering the power consumption to improve the network lifetime. This requires employing the lowest number of sensors. A solution is just to turn on a subset of nodes. This subset should be chosen in such a way to cover the entire region. This can be achieved by partitioning the network nodes and considering a representative for each part in a time slice to perform the responsibilities of all the partition members for full coverage. This will lead to turn on some of the nodes in a time slice rather than all of them.
