摘要

定向天线已被证明具有显著提高吞吐量和减少延迟的潜力,同时需要更低的发射功率,提高LPI/LPD和A/J质量。在军事系统中,由于传感器系统无法移动,部署时间长,以及需要隐身操作,因此对这些特性有很强的需求。在本文中,我们描述和分析了定向天线中基于竞争的mac的重要问题,这是传感器系统特别感兴趣的问题。我们还提供了一种克服这些困难的MAC设计。

On the use of directional antennas for sensor networks
Directional antennas have been shown to have the potential to provide dramatic increases in throughput and reduction in delay, while simultaneously requiring lower transmit power and increasing LPI/LPD and A/J qualities. Among military systems, sensor systems have a strong need for such characteristics due to their inability to move, length of deployment time, as well as a need for stealth operation. In this paper we describe and analyze significant issues for contention-based MACs for directional antennas which are of particular interest to sensor systems. We also provide a MAC design that overcomes these difficulties.
