Transmission Power Control for Wireless Sensor Networks

摘要：

Power control in wireless networks is important to maintain reliable communication links between base stations and nodes, and to maximize the battery life. An energy aware connectivity set based transmission power control protocol is presented in this paper. We augment our distributed protocol with a heuristic that considers energy cost information when making power control decisions. Compared to traditional protocol, our protocol can improve energy efficiency and prolong network lifetime significantly, while networks connectivity is still maintained in extreme scenarios. Simulation results demonstrate our conclusion.
