Optimal Transmission Range for Topology Management in Wireless Sensor Networks
نویسندگان
چکیده
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). However, in data transmission, it is more efficient to communicate with shorter transmission range, even with increased number of nodes in the topology. Therefore, it is necessary to find an optimal transmission range to minimize the total power consumed by the topology management as well as data transmissions. 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, which minimizes the total power consumption.
