Abstract:Based on the fact that many researches only discussed the fixed node's transmitting power, the general WSN was extended so that r and R could be arbitrary, and the node transmission power was variable, its biggest transmitting radius is k times than the smallest radius r. A more accurate analysis was given to gain the optimal network parameters which included the smallest total energy consumption, and the location and energy level which made the longest life expectancy. The results show that the network life can be improved 5 times than that of fixed node's transmitting power only by selecting the optimal transmitting power. When the network hop is single, the location of buffer zone L=2/3R makes the minimum total energy consumption, when the network hop is single, the location of buffer zone L=2/3R makes the longest network life. The overall optimization algorithm is proposed by selecting the optimal of node's transmitting power and the location of the buffer zone. The algorithm can improve network efficiency of energy use more than one order of magnitude.
Keywords:wireless sensor networks  mobile base station  network optimization  energy consumption balancing  network life
