A Wireless Sensor Network (WSN) consists of a large number of small sensors with limited energy. In WSN, long lifetime requirement of different applications and limited energy storage capability of sensor nodes has led the users to find out new horizons for reducing power consumption upon nodes. Power efficiency is a key issue in WSN due to limited power supply. Buffer management is extremely important in the scenario in WSN where the incoming traffic is higher than the output link capacity of the network since a buffer overflow causes power waste and information loss if a packet is dropped.
