In today's world the wireless sensor network has great significant in application like defense surveillance, patient health monitoring, traffic control etc. As WSN utilize radio frequencies so there is threat of interference in network. These threats also include distributed denial of service in which the messages that are sent over the network may be attacked by unauthorized user. It would harm the confidentiality of the network user and the services of network. There are various algorithm that are utilized to detect clone attack in WSN but these schemes only stress on prevention of attack after it is occurred. This would leads to the loss of data and more consumption of limited network resources. So in this work we introduce a new algorithm that is based on DCA along with random walk detection. It would detect earlier the clone attack in WSN and prevent the data loss. The parameters like throughput, energy consumption etc are utilized to analyze the performance of this technique.
