Data aggregation in Wireless sensor Network (WSN) is typically done by some easy technique like averaging. These ways are liable to sure attacks. Refined data aggregation formula would create the sensor nodes less vulnerable thereby achieving the trust of knowledge and name. Secure information aggregation protocol holds nice promise for this purpose. To beat the safety problems in WSN, Particle Swarm optimization Clustering (PSOC) based mostly secure data aggregation protocol is planned. This method makes them not solely collusion sturdy however, a lot of correct and conjointly achieves quicker convergence. Then the optimized cluster head is chosen for data aggregation by PSO. The cluster formation is reduced the ability consumption and bandwidth allocation. Trust and name have a big role in supporting the operations of a large vary of distributed systems, from wireless detector network to social network. Assume that the random elements of detector errors are independent random variables with a Gaussian distribution. If error distribution of sensors is either familiar or calculable, planned algorithms may be custom-made to alternative distributions to realize associate best performance. A sensor node solely accepts data things aggregate by licensed users. So as to make sure security, every step of the prevailing data aggregation protocol runs ought to be known then protected. The first challenge of providing security functions in wsns is that the restricted capabilities of sensor nodes in terms of computation, energy and storage.
