The Power Control Method in Sensor Networks of LQI-based Mean Value
Xu Hua · Journal of Logistical Engineering University · 2009
The power control method of the proximity graph is one of the most important technologies in topology control of sensor networks.This paper compares and analyzes the characteristics of some link quality index such as PRR,RSSI,LQI,and uses the mean value of link quality indication(LQI) as distance measurement to construct link quality proximity graph(LQPG).The result of simulation proves that LQPG has bounded degree,and under circumstance of variational link,has lower average power and longer network survival period.
