Topology management protocols aim to minimize the number of nodes in densely distributed sensor networks that constitute the topology. Most protocols construct the topology with a fixed transmission range (i.e. maximum transmission power). With respect to the power consumed by data transmission, it is more efficient to communicate with shorter transmission range, even with the number of nodes in the topology increased. In the sense of minimizing the total power consumed by the topology management as well as data transmissions, it is necessary to find an optimal transmission range. Moreover, data rate is also an important factor to determine the total transmission energy. In this paper, we obtain the optimal transmission range for a given data rate and maximum transmission power to minimize the total power consumption.
