Energy Efficient PEGASIS Routing Protocol for Wireless Sensor Networks

Wireless Sensor Networks (WSN) for communication between the nodes uses a different type of protocols. This paper proposed improved Power-Efficient Gathering in Sensor Information System (PEGASIS) chain based routing protocol. The protocol are sensor nodes connected with next near nodes and selects the leader node for communication to the base station but this causes some problem when used for a long distance between nodes and base station. Such problem causes large transmission delay, selection of a leader, scalability, and unbalanced energy consumption. For enhancing the performance improved PEGASIS protocol is proposed which provides better energy efficiency and good lifetime sensor networks as compared to the unique PEGASIS protocol.
