Abstract
Ad hoc network with directional antennas has become an active research topic because of the potential capacity increase through spatial reuse. Currently researchers have attempted to apply conventional ad hoc routing protocols (e.g. DSR, AODV) on this type of networks. The routing schemes are typically based on the shortest path metric. However such routing approach often suffers long transmission delay and frequent link breakage at the intermediate nodes. This is caused by a unique feature of directional transmission commonly known as "deafness"[1]. To address this problem, we have introduced a new multi-path routing scheme to explore the advantage of spatial reuse for reducing per hop medium access delay. In this work, an analytical and numerical analysis of the directional ad hoc network behavior is presented, along with an introduction of our multi-path routing scheme and a discussion on the effectiveness of this scheme in balancing per-hop delay and hop-count for packet forwarding. Simulation results demonstrate a clear performance improvement by using multi-path routing for directional ad hoc networks.
