Abstract Most applications of Wireless Sensor Networks (WSNs) assume the presence of single-channel Medium Access Control (MAC) protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because...

Optimal design of Medium Access Control (MAC) layer is one of the most important challenges in Wireless Sensor Networks (WSNs). Main problems in MAC layer of WSNs include sleep/wakeup scheduling and its overhead, collision and energy used...

Major problems in the Medium Access Control (MAC) of Wireless Sensor Networks (WSNs) are: sleep/wake-up scheduling and its overhead, idle listening, collision, and the energy used for retransmission of collided packets. This paper focuses...
