Abstract—We have presented a balanced routing protocol for Mobile Ad-hoc Networks using the smart antenna in this paper. Multipath routing can be effectively used to maximize the utilization of network resources for real-time traffic. In mobile ad-hoc network, this approach can suffer from co-channel interference or route coupling due to simultaneous transmission of packets via multiple routes. We use zone-disjoint routes and define maximally zone disjointness as route selection criteria. An adaptive routing strategy is proposed that use the advantages of directional antennas in ad hoc networks through the selection of maximally zone disjoint routes. Zone-disjoint routes would reduce the route coupling effect in wireless media by selecting routes in such that it produce minimal interference among communication over multiple routes. The proposed routing protocol provide effective load balancing in wireless media and it is implemented for both single path and multipath routing on ad hoc networks with directional antennas. Simulation results show that zone-disjoint single path routing can produce better throughput compare to multipath and AODV (Ad-hoc on-demand distance vector) routing protocol for more number of simultaneous communications.
