Energy-Balanced by Transmission Range Adjustment with Full Sensing Coverage of Target Area for High-Density WSNs
An optimal energy assumption and sufficient sensing coverage are challenges for sensor network design.In this paper,we firstly design an approach called Full Sensing Coverage of Target Area(FSCTA)by dividing a circular network model into several homogeneous sectors.In this approach.the route nodes transmit data to base station(BS) along the sides of these sectors and the radio of nodes can cover all areas of target area.Then a scheme called Energy-Balanced by Transmission Range Adjnstment(EBTRA)in FSCTA is presented to choose the optimal route nodes and their transmission ranges by sleeping schedule.Simulation results show that our flexible approach can not only keep the energy consumption well balanced among the nodes,but also can minimize the total energy consumption obviously.
