Route Recovery Mechanisms for Ad Hoc Networks Equipped With Switched Single Beam Antennas

Overview This paper proposes a novel three phase route recovery mechanism for routing over switched single beam directional antennas. The paper enhances the popular Dynamic Source Routing (DSR) protocol to the underlying directional layer and includes an improved broadcast mechanism to facilitate an efficient route discovery. In the event of a link failure, the optimized Directional Routing Protocol (DRP) proceeds in three phases to recover the route to the destination; antenna beam handoff; local route recovery; and zonal route recovery. The paper has compared the performance of DRP with the DSR protocol over both omni-directional and directional antenna models in conditions of varying network mobility. The results clearly indicate that DRP is robust to link failures even in highly mobile scenarios.
