Low energy assumption is one of design challenges for data transmission in sensor networks. 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-efficient with optimal balanced-factor (EEOBF) by Transmission Range Adjustment is presented and a heuristic algorithm (HA) is given to choose the optimal route nodes and their transmission ranges. Simulation results show that our flexible approach not only can keep the energy consumption balancing among route nodes, but also can minimize the total energy consumption obviously.
