摘要
定向链路具有传输距离远、抗干扰能力强、能够在空间上大大提高带宽资源重服使用效率,因此采用高增益的定向链路实现ad hoc组网引起了强烈的关注,并且该技术得到了广泛的应用。在基于定向天线传输的自组织网络中,邻居发现与定向链路方向跟踪是提高网络效率的关键,也是难点问题。首先介绍了采用定向传输与接收的、具有确定性发现时间的快速邻居发现方法,然后叙述了应用定位信息实现动态跟踪定向链路波束方向的方法。
The directional link, with long transmitting range and high resistance to jamming, could increases repeating exploitability of bandwidth in space, so the ad hoc network with high-gain directional links receives much attention, and this technology is widely used. The neighbor discovery and tracking in the ad hoc network with directional antenna is the key to raising network efficiency. The quick neighbor discovery algorithm is described first, this algorithm adopts directional transmission and reception and is of determinable discovery time. And then the tracking method for directional link beams by applying the location information is also given in this paper.
