Improved Security and Avoid Clone Attack in Wireless Sensor Network

Kulwinder Singh, Sheenam Malhotra

Abstract: In the wireless sensor networks the network nodes are used for the sensing the information from the various types of non-reachable areas. Wireless sensor nodes has been used for the sensing the information from harsh environment. In these nodes sensors of different types has been used for collecting information. Main problem in this is to detect the node having clone attack, because each and every node has same id and locations at different position on same interval of time. This problem has also been arising in clusters in which clusters replicate and the main problem arises when cluster head replicate.
