    Abstract: 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 protocol for energy efficiency designed for wireless sensor networks. It adjusts transmission... Show More
