On Reducing Broadcast Transmission Cost and Redundancy in Ad Hoc Wireless Networks Using Directional Antennas

Free registration required

Executive Summary

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 researches have focused on applying directional antennas to broadcasting. In this paper, the authors 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.
