Power Control in Wireless Sensor Networks
Abstract:The problem of power control in wireless sensor networks is important for network connectivity and lifetime. This paper analyzes how the power control technology affects the performance of network layer, MAC layer and physical layer. Then an energy aware degree-based power control protocol is presented in this paper. Compared to traditional protocol, our protocol can improve energy efficiency and prolong network lifetime significantly.
Keywords: Wireless Sensor Network, Power Control, Node Degree
