Secure data transmission is essential in Wireless Sensor Network (WSN) to protect sensitive communications in the network. To improve the security of such network, this paper proposes a successful routing among authentic nodes with adversary nodes inside the network and forms the secure wireless sensor network. The authentication protocol will enable the receiving end to affirm that the packet has originated from a genuine node. It will preserve the integrity as well as authentication and confidentiality. Impersonation attack can be prevented in which a node will pretend like other node and sends the request to base station.
