Devices existing within a wireless sensor system are small in size and their battery capacities are very limited. In addition, diverse channel environments may be configured for them. To overcome various constraints and efficiently utilize the energy of sensor nodes, transmission power control (TPC) technology may be employed. This paper describes our attempt to resolve problems with existing TPC algorithms, reduce the number of unnecessary changes in transmission power level (TPL) using the slope value of linear regressed equation, and present an algorithm for deriving TPL in a fast and appropriate manner. Through an experiment, in this study, we not only derive proper weight value of the proposed algorithm but also compare its performance with that of existing algorithms by analyzing the numbers of control packets, drop packets, and energy consumption.
