Wireless sensor nodes has been used for the observing the information from harsh environment. Wireless sensor networks are of two main types, which are static wireless sensor nodes and mobility wireless sensor networks. In Mobile Wireless Sensor Networks the main threat in the network is security. Various types of attacks occurred in these networks. A clone node can create a black hole or wormhole attack include antagonist can use them in different ways. This attack can transmit false information to all authorized nodes. The clone attack is very suitable for antagonist. For this attack antagonist has not to be compromise for number of nodes. The antagonist can do cloning of one node and can predict other nodes through this node. It falsifies its positions at different times at different locations. Main problem in this is to identify 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 clumps in which clusters replicate and the main problem arises when clumps head replicate. In purposed work LEACH protocol will be used for clustering.
