Backbone Nodes Based Stable Routing for Mobile Ad Hoc Networks

The recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. This paper proposes a scheme to improve existing on-demand routing protocols by introducing the concept of stable backbone based node scheme in network topologies scenario. The scheme establishes the multi paths without transmitting any extra control message. It offers quick adaptation to distributed processing, dynamic linking, less memory overhead and loop freedom at all times. The Scheme has been incorporated with the AODV and DSR protocols. The extensive simulation has been done for the performance evaluation; it clearly shows that the scheme performs very well with increasing packet delivery for different network scenarios.
