Wireless sensor networks have predefined objectives which require them to connect and communicate with other nodes. During communication these nodes transmit and receive data and other control packets. This paper proposes swing-MAC, a Medium Access Control (MAC) protocol for energy efficiency designed for wireless sensor networks. It adjusts transmission power level in a swinging mode where transmission power level keeps swinging between minimum and maximum requirement of the network. Minimum and maximum transmission power level is based on the expected coverage between nodes. As transmission power keeps swinging between two intervals on cyclic basis this leads to energy conservation resulting in a longer battery life.
