Secret key establishment for self healing of adhoc networks

Wireless networking is one of the most emerging technology. It has so many applications. This is possible even in extremely unpredictable and dynamic environments. The major challenge of wireless type of communication actually lies in the environment in which this wireless type of communications travel through, because it is mostly unpredictable. Problem of breaking route is very common. So the Wireless networks that can actually fix their broken communication paths and links are gaining popularity. When a new mobile node joins the network and it does not exhibit any trust with other nodes in the same network, this casues problem of secure routing. In this paper, secret key has been established for symmetric encryption for self healing using Diffie-Hellman.
