In Wireless Sensor Network, due to the power restriction of nodes, efficient routing is very important in order to save the energy of sensor node and to enhance the lifetime of the network. In this paper, a new protocol i.e. O-PEGASIS (Optimized PEGASIS) has been designed to reduce the complexity of chain in PEGASIS. A new approach has been used to overcome the problem of PEGASIS by using the Honey Bee optimization technique. The results of new protocol i.e. OPEGASIS have been compared with PEGASIS and EAPHRN. Simulation results show that the lifetime of O-PEGASIS is better as compared to PEGASIS and EAPHRN.
