Wireless Sensor Network (WSN) is a collection of nodes where each can equipped with sensors to compute and communicate various parameters of a system. WSN is an emerging research in the field of industry, healthcare, agriculture, security and biomedical applications. Efficient routing of data from source to destination is critical in terms of limited resources. Location based routing protocols are less complex in comparison with other protocols. Finding accurate node location has significant for enhancing routing performance in cooperative WSN. In the proposed solution nodes with accurate location information are selected as reference nodes. CramerRaoBound (CRB) algorithm select the reference nodes which give accurate location information. In this paper Cooperative Distributed Particle Swarm Optimization (CDPSO) localized routing algorithm with optimum references is proposed. CDPSO is used to find the accurate nodes locations. Proposed mechanism implemented and tested with various parameters. Simulation results show that CDPSO with optimum references performs better in terms of lifetime, complexity, Packet Delivery Ratio and throughput.
