Conceptual representation and Survey of Dynamic Power Management (DPM) in Wireless Sensor Network

A Wireless Sensor Network (WSN) comprises many sensor nodes each one containing a processing unit, one or more sensor, a radio for data communication and power unit usually equipped with a low capacity battery. All sensors present in wireless sensor network are battery operated devices which have limited battery power. After the deployment of sensor nodes it is not possible to replace each and every battery in the network. Therefore optimal energy consumption for WSN protocol is a necessity. In a number of proposed protocols periodic sleep and wake time is used for the reducing the consumption of energy but these protocols result in increased end to end delay.
