Abstract : Energy efficiency and security is the major problems identified in wireless sensor networks. This work introduces the Secured Cooperative communication protocol in wireless sensor networks for establishment of cooperative clusters during transmission of data in a collective way. In the cooperation process using cooperative transmission protocol, recruitment policy helps the nodes to co-operate each other. Cluster head on one node thick path recruit neighbouring nodes to assist in communication. Proposed method aimed to build security between the intermediate cluster nodes and also minimize the overall energy consumption and increase the transmission reliability of packet delivery between a source and a sink in an unreliable wireless network by giving some level of cooperation among them. Cooperative Transmission Protocol that uses any wireless networks communications between any source node and sink node can be with optimal energy and not compromising with the reliability of transmission to decrease packet loss. In order to bring the security among the nodes inside the cluster the method called Rijndael algorithm is used as an Advanced Encryption Standard (AES). AES provides flexibility and security between the systems when compared with other cryptographic algorithms. To enhance efficiency of sensors, the existing algorithm found inefficient. Hence with all accounting of the existing systems, this work concentrates on reducing energy consumption by selecting only few/optimal node and also maintains a data cache until an acknowledgement is received from receiving cluster head upon successful transmission.
