Recently, Wireless Sensor Networks (WSN) have come to require an energy efficiency and a guaranteed delivery delay time, on the contrary to traditional Medium Access Control (MAC) protocols that have mostly aimed for a high throughput. In order to satisfy these new significant requirements, many of the newer WSN MAC protocols employ duty cycled mechanism, in order to improve energy efficient techniques in the MAC layer. This duty cycled mechanism is oriented to the toggling of the transceiver's conditions composed of the wakeup and sleep states. However, regrettably, the channel conditions of a wireless network can be changed anytime according to the traffic congestion. If a high congestion is present, an insufficient wakeup period can cause the successful communication ratio to worsen. This can be a weakness in previous duty cycled mechanisms due to their lack of consideration for the network conditions. Therefore, we have devised and designed an efficient new scheme, the adaptable wakeup period, which can resolve this issue. We present analyses and the simulated results of our work, together with a comparison between the synchronous and asynchronous MAC protocols, using two types of analysis models that we suggest.
