On Reducing Broadcast Transmission Cost and Redundancy in Ad Hoc Wireless Networks Using Directional Antennas
—Using directional antennas to conserve bandwidth and energy consumption in ad hoc wireless networks has attracted much attention of the research community in recent years. However, very few research has focused on applying directional antennas to broadcasting. In this paper, we propose a virtual link reduction (VLR) based broadcasting protocol for ad hoc wireless networks using directional antennas. Based on 2-hop neighborhood information, VLR does not rely on any location or angle-of-arrival (AOA) information. VLR is a localized or distributed protocol and it achieves full delivery. VLR operates on top of any existing broadcast routing protocols. In VLR, no node rebroadcasts a given packet more than once. No physical link is actually reduced, but if a packet has already been forwarded to the end node of the current link, the packet is not forwarded anymore, that is, this link is virtually reduced. To evaluate the performance of the proposed VLR based protocol, we conduct extensive ...
