Sonu Pant, Ramesh Kumar, Ajeet Pratap Singh · 2017
Modern improvement in micro manufacturing technology authorized wireless communication to evolution of low power, low cost and multitasking sensor nodes. Multiple sensing applications take place sincerity as an outcome. It include environmental monitoring, disaster management, object tracking, battlefield surveillance, intrusion detection, etc. In a wireless sensor network (WSN) when data sensed and passed from one sensor to another, there arise a problem of limited battery power. Sink relocation is a method for extend the network lifetime of a WSN. In this paper a new approach of adaptive sink transmission and relocation (AST-EASR) introduces to extend the network lifetime of WSN. Our proposed method categorized in two way, sink transmission and relocation. Sink transmission operation performed by checking the receive signal strength using of heterogeneous lower energy consumption. Other side the task of sink relocation performed by grid based sensing (prior for advance node). Simulation results show that our proposed AST-EASR maximized the network lifetime of WSN as compare to conventional approaches like, energy aware sink relocation (EASR) and one-step moving scheme.
