Abstract :
Wireless networking is an emerging field with
its potential applications in extremely unpredictable and
dynamic environments. Individuals and industries choose
wireless because it allows flexibility of location, whether that
means mobility, portability, or just ease of installation at a
fixed point. Wireless networks that fix their own broken
communication links may speed up their widespread
acceptance. The challenge fo
r wireless communication is
optimized handling of unpredictable environment through
which communications travels. Despite early problems in
overcoming this pitfall, the newest developments in self-
healing wireless networks are solving the problem. The
changes made to the network architectures are resulting in
new methods of application design for this medium. This
paper presents an overview of self healing networks and a
new scheme has been proposed that tries to heal the routing
when a link failure occurs. The scheme can be incorporated
into any adhoc on-demand unicast routing protocol. In this
research work, the proposed scheme has been incorporated
to AODV and observation is that the performance has been
improved. The simulations have been carried over NS2
simulator with existing schemes and proposed scheme.
Simulation results indicated that the proposed technique
provides robustness.
