Data fusion is an efficient method of optimization in any wireless network. Providing an effective data aggregation in MWSN is considered to be important where the topology changes occur in often. This may result in collecting and reporting the data of same event from multiple resource to the base station called repetition of data. In this paper, an efficient data aggregation algorithm called SD-MDCH (Secured Data Aggregation with Mobile Double Cluster Head) is proposed to avoid repetition of data and to prevent malicious node from attacking the network. Here, two CH nodes namely MCH and ACH is used in intra and inter cluster communication respectively. MCH finds the forwarding factor from information table and PPMC coefficient value based on the data received from member nodes. If the threshold conditions are attained, MCH node fuses the data with a MAC value and forward to ACH. Simulation results shows that the proposed algorithm balances the load through effective data aggregation.
