Energy-Efficient Target Monitoring Algorithm for Wireless Sensor Networks

[摘要] In this paper, an energy-efficient target monitoring algorithm for wireless sensor networks have been reported. Here, we have proposed new energy efficient algorithms HADEEPS, based on the scheduling that allow sensor nodes can interchange its state into idle, sleep and active modes. The network lifetime increases with the number of sensors at different targets and sensing range. The simulation results for target supervising protocol, HADEEPS verify that with the adjustable sensing range, heterogeneous nodes and different targets, the overall network lifetime improved as compared with existing protocols.
