Wireless sensors network are mainly used for monitoring application. So the wireless sensor networks are easily attacked by attacker. In this paper, security mechanism is presented to detect and prevent the sinkhole attack by using mobile agent and Md5. Wireless sensor network have limited resources when compared to the traditional network. So the wireless sensor network has limited power, storage and security mechanism. Mobile agent detects the sinkhole affected node and Md5 is used for message encryption and decryption.
