Wormhole Technique used for Selective Jamming in Wireless Sensors Networks

The wireless networks are facing one or more problems day to day. One of the networks most sensitive to the denial of service attack. In wireless network the communications occurs through the nodes that send and receive the packets through the broadcast communication. The attacker, due to this reason can easily use eavesdropper technique and attack the network. The wireless networks are exposed to security threat called jamming. This paper discuss on the various attack of jamming occurrence. This leads to the denial of service of attack. To overcome these attacks, we develop three schemes that prevent the attacker from attacking the packets. Then we analyze the security of our schemes.
