ABSTRACT
The increase of the technology revolution is encouraging WSN to be used in different sectors and for different purposes. These sensor node are used for collecting and sending data and transmit among the networks. Each node can move freely in any direction, and changes their links to other devices frequently. Security is an essential part of Wireless Network. Due to its dynamic topology, resource constraints, no centralized infrastructure and limited security, it is vulnerable to various attacks and black hole and gray hole attack is one of them. In this attack, the malicious node advertises itself as having the shortest path to the destination and falsely replies to the route requests, and drops all receiving packets. Where it is easy for an attacker to physically capture some of the legitimate nodes, copy credentials, reprogram them and re-deploy them in the WSN. Such type of attack is called Node Replication or Misdirection Node Attack. With this attack an attacker can easily gain significant control over the WSN. Basically, this mechanism provide the security of RSA and Md5 algorithm in WSNs.

Keywords:
Wireless sensor network, black hole, multiplebase station etc.
