The energy efficiency in the WSN is one of the very important Performance Indicator. Sensor network is a distributed event-based system that differs from traditional communication network. Sensor webs consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. PEGASIS (Power-Efficient GAthering in Sensor Information System) is chain based protocol which is used to construct chain of sensor nodes. In the proposed work BBO is implemented along with PEGASIS to get the shortest chain for every round.
