A Distributed Energy-Efficient Target Tracking Protocol for Three Level Heterogeneous Sensor Networks
In this paper, a distributed energy-efficient target tracking protocol for three levels heterogeneous wireless sensor networks have been reported. The authors have proposed heterogeneous distributed algorithm HADEEPS, based on the scheduling and adjustable range that allow sensor nodes to go into different states. Here, three types of sensor nodes i.e. super, advance and normal nodes are used in their simulated network. These sensor nodes used through a heterogeneity model that directly impact on the battery power of sensor nodes and shuffling the cover set over time. The simulation results for target tracking protocol HADEEPS verify that the overall network lifetime significantly improved as compared with existing protocols. Lifetime of the network increases with three level heterogeneity because energy consumption is low as compare to homogeneous.
