The lifetime of wireless sensor networks (WSNs) decreases with the increasing payload, such that extending the network lifetime has become a hot topic. This paper proposes a distance-based transmission rate sexlection algorithm, maximum emission rate (MER) determination, to select the pairwise maximum effective transmission rate in a given WSN environment. The proposed work is founded on two observations, one is the logarithmic relationship of internode communication distance to data transmission rate, the other is the linear relationship of receiving current to data transmission rate. The proposed work helps to reduce data transmission duration, and finally to increase the network lifetime. Simulation results show that the application of MER in existing network protocols extends 300% plus network lifetime while ensuring communication success rate.
