Hiding the Sink Location from the Passive Attack in WSN

Due to unattended nature of Wireless Sensor network makes it's vulnerable to security issues. The sensor nodes in the wireless sensor networks collect the information from the environment and send the information to a sink node so it's a main concern to preserve the anonymity of the sink node from the attacker. The attacker can conceal the identity of the sink node by performing the traffic analysis inside the network. In this paper we are proposing a method that can preserve the identity of the sink node. The simulation results demonstrate that the proposed method can hide the location information of the sink node effectively and efficiently.
