Abstract

Denial of Service attacks poses a serious threat to the intended service provided to the users. Detection of the jammers is quite easy in case of external locality since they possess a significant pattern of attack and route to attack the victim. Being an internal attacker, the node would have adequate knowledge over the present defensive mechanism and additional tools to masquerade their identity. The proposed method includes a detection technique for identifying the internal compromised node based on the location attributes and markings of the packets. The packets are transmitted towards the destination node using dedicated channels and timing without the disclosure of the keys for decrypting the message to every user node. This method involves the detection of a attack with the help of marked attributes in the packet. The hash function marks all the blocks of the message, with the link to the preceding and succeeding packet. All the packets are required to reassemble the whole meaningful message. The packets without those attributes would be regarded as the attack packet. On detection of the attack, a dynamic routing algorithm would determine the least used bandwidth for previous communication and allocates a dedicated channel between the source and destination.
