This paper studies the design of optimal location of buffer area in a movement-assisted data gathering scheme. In [7], the author only considered a network scenario where rLtR and the transmission power of sensor was fixed. This paper extends the network to a general network where the relationship between r and R is arbitrary and the transmission power of sensor is variable. In the network, the maximum transmission radius is k times of the minimum transmission radius. In order to minimize the total energy consumption of network and maximize the network lifetime, this paper employs a more accurate analytical method to select parameters of the transmission power level and location of buffer area. Finally, a conclusion is obtained that the scheme using optimized location of buffer area and transmission power excels greatly the one that employs fixed transmission power in the scenario of improving the network lifetime. Therefore, our study on the parameter selection of network can present a better guidance on the optimization of wireless sensor networks.
