K-Coverage Algorithm Based on Network Model in Wireless Sensor Network

摘要

This paper presents K-Coverage algorithm based on network model in wireless sensor network, firstly, establish the affiliation between the sensor nodes and target nodes through the network model, present a method to compute the coverage expected value of the monitoring area; secondly, in the network energy conversion, using scheduling mechanism in sensor nodes to attain the network energy balance, and achieve different network coverage quality through different nodes energy conversion. Finally, simulation results show that K-coverage algorithm can effectively reduce the number of active nodes meeting certain coverage requirements and then improve the network lifetime.
