摘　　要：基于定向天线的移动自组织网络被广泛应用于军事领域,尤其对于具有易实施、高隐蔽性、高保密性要求的空基网络,定向天线比全向天线更具有优势,它具有更远的传输范围,减小了节点间的相互干扰,能够实现空间复用能力的提升。但是定向天线的引入在增加通信距离的同时也会带来一些问题,给许多协议层带来破坏性的副作用。目前,国内外研究人员已提出多种算法来解决这些问题。结合空基网络的复杂性,研究了国内外提出的基于定向天线的移动自组网数据链路层和网络层的各类算法和协议,总结对比近年来定向邻居发现算法、媒体访问控制协议和定向路由协议三种关键技术,并提出更适合用于空基网络的技术与协议,最后对这些算法和协议的下一步研究提供了一些方向。Mobile ad hoc networks based on directional antennas are widely used in the military field,especially for airborne networks with the requirements of easy implementation,high concealment and high confidentiality.Directional antennas have more advantages than omni-directional antennas,which have longer transmission ranges,reduce mutual interference among nodes,and are able to achieve the improvement of spatial multiplexing capability.But the introduction of directional antennas can create problems while increasing the communication distance,causing disruptive side effects to many protocol layers.Currently,researchers at home and abroad have proposed a variety of algorithms to solve these problems.Combined with the complexity of airborne networks,it studies various algorithms and protocols proposed at home and abroad for the data link layer and network layer of mobile ad hoc networks based on directional antennas.It summarizes and compares three key technologies in recent years,namely,directional neighbor discovery algorithm,medium access control protocol and directional routing protocol.Techniques and protocols that are more suitable for use in airborne networks are proposed.Finally,it provides some directions for further research.
