Use of directional antenna in the context of ad hoc wireless networks can drastically improve the medium utilization through overlapping communications in different directions. However, all the existing routing schemes proposed in this context rely on the use of omni-directional antenna. The use of directional antenna to find out a route and use it in data communication has not been explored properly. We have proposed a modified link-state based table-driven routing protocol that captures the approximate network status periodically without generating lot of control traffic and makes all nodes in the system topology-aware. It uses the directional capability of adaptive antenna for capturing, disseminating and using the network information for directional routing. Additionally, we have attempted to address the issue of managing an uninterrupted connection between a source and a destination over adaptively selected routes in temporal domain. The protocol enables each node to constantly evaluate network conditions and to take decisions on adaptive route selection.
