摘要:

近年来,无线自组织网络(WANET)因为可以大量应用于不同领域而受到广泛关注。为适应复杂的任务需要,WANET需要提供更高的通信质量。与全向天线相比,定向天线具有干扰更低、空间复用更好、传输距离更长、覆盖范围更广和链路容量更高等优点。为提升通信质量,定向天线越来越多地被应用于自组织网络,因此对定向天线的应用进行综述。首先介绍定向天线的分类及优缺点;其次,研究梳理定向天线在WANET路由中的具体应用,包括能够提高安全性、减少竞争和提高能量效率以及提升服务质量;再次,针对路由开销较大的路由发现阶段重点分析定向天线的优化措施;最后,总结定向天线在WANET中能够更加广泛应用所面临的挑战。

Abstract:

In recent years, Wireless Ad hoc NETwork (WANET) has received extensive attention because they can be widely used in different fields. To meet the needs of complex tasks, WANET needs to provide higher communication quality. Compared with omni-directional antenna, directional antenna has the advantages of lower interference, better spatial multiplexing, longer transmission distance, wider coverage and higher link capacity. In order to improve the communication quality, directional antennas are increasingly used in ad hoc networks. Therefore, the applications of directional antenna were summarized. First, the classification, advantages and disadvantages of directional antennas were introduced. Then, the specific applications of directional antennas in WANET routing were studied, including the ability to improve security, reduce competition, improve energy efficiency, and improve quality of service. Thirdly, the optimization measures of the directional antenna were analyzed in the route discovery stage with high routing overhead. Finally, the challenges facing the wider application of directional antennas in WANET were summarized.

Key words: directional antenna, Wireless Ad hoc NETwork (WANET), communication safety, Quality of Service (QoS), route discovery
