An Constructive For Secure Data Aggregation Protocol in Wireless Sensor Network

Wireless sensor networks are randomly deployed and responsible for monitoring wide geographical area. In WSN, the aggregation of data is very complex because of its limited power and computing capabilities. Issue in data aggregation is that the data may be passed on malicious node. All existing data aggregation technique suffers the security issues because of the transfer of large amount of data. In this paper we propose a protocol named as Secure Data Aggregation Protocol(SDAP) which identifies the malicious node by providing a logical group in the form of tree topology. In the tree topology the aggregate nodes are formed as aggregators, which is a non-leaf node and high level of trust is required to provide a better approximation and accuracy against the security threats. Thus the data is securely aggregated and the efficiency is achieved.
