Enhancement of Security and Performance in Wireless Mesh Networks Using Multi-Key Generation

A Wireless Mesh Network consists of large number of mesh nodes. The message called Position-Aware and Secure Efficient Mesh Routing which has been sent from one node to another during the data communication. When the communication takes places among nodes, packet data is sent from one node to another node which can cause a chance of falling the nodes in the attackers trap and routing between the nodes may get lost due to concussion. Hence the security level of the data communication is very low. Due to these reasons the performance is very poor due to high node density. The user position information cannot able to identify the location of sending the messages from source and destination due to size of the message is less. In order to overcome these drawbacks, a new method is proposed called Multi-Key Generation, which uses different encryption and decryption multiple key pairs in order to overcome security problem, and to verify the message from falling on attacker's trap an algorithm is introduced called Digital Signature Algorithm, this method which improves the security level by detecting the attackers and performance of the node density will be improved.
