Enhanced Anti - Jamming Protocol in Wireless Mesh Networks

Nowadays jamming causes the major data loss in mobile communications. During the transmission time Anti-jamming technique can be used to transmit intermittently at low power in order to conserve energy. Here we use 802.11wireless network technology and this is to access the functions of the physical layer. There are two functions called Rate Adaptation and Power Control are used to find out whether the attackers involve over the transmission. Attackers involve and send the unwanted messages from source to the destination and use more power. During the transmission time the original messages were not sent properly and occupy more power. First, the Rate Adaptation Algorithm controls the data rate during transmission and increases the packet delivery ratio. Second, Power Control technique is used to find out who is using unwanted powers. Attackers are motivated to use a random jammer to make the jammers to sleep intermittently and increase its lifetime and decrease the probability of detection. The two types of jammers are Deceptive-random jammer and Reactive jammer model. So we primarily consider the Deceptive-random jammer model. Moreover, Reactive jammers are not easily available since they are harder to implement and require special expertise on the part of the attacker.
