Energy Level Selection for Wireless Sensor Network with Variable Transmit Power
Wang Jian-ming · Jisuanji gongcheng · 2009
In this paper, a wireless sensor network node transmission power is variable, whose radius of maximum emission energy is k times of the smallest radius r, namely the kr wireless sensor network.The best suitable energy radius of ir is studied comprehensive.Through rigorous mathematical analysis, the energy consumption formula is given, and the compute method of optimal energy emission level k is gained.The optimization transmit power can greatly improve network life compared with transmit power, which plays the important instructing role for wireless sensor network.
