Wireless Sensor Networks is having broad area for researchers due to their wide range of application potential in areas such as target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems. In designing of Wireless Sensor Networks MAC protocols, conservation of energy is the main issue. Energy efficiency is a major consideration while designing wireless sensor network nodes. Lowering the energy consumption may result in increase of time delay from

To address the tradeoff between energy consumption and time delay, this paper proposes a MAC protocol based on sleep schedule of sensor node dynamic duty cycle. This paper propose that if any node is having data to send to the desired destination, it first checks the idleness of medium from where the data is to be sent and then sends an AWAKE signal to wake up the node for data reception. Else, all the nodes are kept in SLEEP state, so that energy conservation is more.
