摘要：
This paper aims to design an energy efficient Medium Access Control (MAC) for IEEE 802.15.4 based Wireless Sensor Networks (WSN). This is achieved by replacing the currently existing common-range maximum transmission power with the concept of dynamic and adaptive transmission power control. Various parameters like Link Quality, Received Signal Strength, MAC collisions, are considered for exercising the control on transmit power. These parameters are fuzzified and optimal transmission power levels are chosen based on Fuzzy decisions. The Sensor Network scenario is simulated with and without power control using Network Simulator NS2 and the comparative performance is analysed for a chosen network. It is seen that sensor network with power control saves energy without degrading the throughput of the network.
