定向天线的Ad hoc网络邻居发现

内容简介：在Ad hoc网络中邻居节点发现（Neighbor Discovery）是网络初始化中的重要步骤之一,节点邻居的信息对于几乎所有的链路选择和路由算法都有着重要的影响,特别是在采用方向性天线时邻居发现不仅难度更大而且其影响作用也更明显。通过分析在采用方向性天线时的Ad hoc网络中的邻居发现算法,总结出了其一般步骤,即首先通过判断网络规模来进行天线收发模式选择算法和扫描图案的选择,然后再设计相应的通信握手协议。

Abstract：Neighbor Discovery in Ad hoc network is a crucial step in network initialization. The knowledge of a node＇s neighbors is essential for almost all link selection,routing algorithms and so on,particularly the neighbor discovery using directional antennas,which is more challenging and plays a more important role. This paper analyzes neighbor discovery algorithm in Ad hoc network using directional antennas and proposes general steps in implementing the neighbor discovery algorithm.
