Abstract :
Low energy assumption is one of design challenges for data transmission for sensor network. In this paper, we firstly compare the total energy consumption rates of direct transmission protocol, hop-by-hop transmission protocol, direct-hop transmission protocol and energy-balanced transmission (EBT) approach by simulations, and identify the drawbacks of the above protocols respectively. Then a scheme called energy optimized and balanced by transmission range adjustment (EOBTRA) is presented and an iterative algorithm (IA) is given to choose the optimal route nodes and their transmission ranges. Simulation results show that our flexible approach not only can minimize the total energy consumption obviously, but also can keep the energy consumption balancing among the nodes.
