摘要:The increased usage of directional methods of communications (e.g. directional smart antennas [15], Free-Space Optical transceivers [19], and sector antennas) has prompted research into leveraging directionality in everylayer of the network stack. In this paper, we learnt how the concept of directionality can be used in layer 3 to facilitaterouting under contexts of 1) wireless mesh networks, 2) highly mobile environments, and 3) overlay networks throughvirtual directions. In the context of wireless mesh networks, we introduce Orthogonal Rendezvous Routing Protocol(ORRP), a lightweight-but-scalable routing protocol utilizing the inherent nature of directional communications to relaxinformation requirements such as coordinate space embedding and node localization. The ORRP source and ORRPdestination send route discovery and route dissemination packets respectively in locally-chosen orthogonal directions.We show that ORRP achieves connectivity with high probability even in sparse networks with voids. ORRP scales wellwithout imposing DHT-like graph structures (eg: trees, rings, torus etc). We show that MORRP achieves connectivitywith high probability even in highly mobile environments while maintaining only probabilistic information aboutdestinations. MORRP scales well without imposing DHT-like graph structures (eg: trees, rings, torus etc). We will alsoshow that high connectivity can be achieved without the need to frequently disseminate node position resultingincreased scalability even in highly mobile environments. We will also evaluate the metrics of reachability, statemaintenance, path stretch, end-to-end latency and aggregate network good put under conditions of varying networkdensities, number of interfaces, and TTL values
