Abstract: In present scenario the, Ad Hoc and Wireles Sensor networks render a remarkable service in case of distance or unreachable areas. The WSN are having large number of sensor nodes which are randomly spread over according to size of the area available. These sensors will function as processing of data for connecting the data to the wireless channel. The processing, transmission and reception and sensing the channel need power. Power is supplied to nodes with their batteries. The problem is in focus to reduce power consumption by these nodes according to the area usage. Thus, it is not possible in some cases to replace or change the battery. It is in need of a protocol which makes these nodes work with low battery power. Existing MAC layer protocols are not much more energy efficient and it is based on CSMA technology. To achieve low power level target, it is proposed WiseMAC protocol which is also based on CSMA but with preamble sampling. It shows very good reduction in power consumption. WiseMAC protocol is an asynchronous protocol and works very well in case of adaptive traffic conditions. To make WiseMAC energy as an efficient, it is done with reducing duty cycle and contention window of proposed protocol.
