移动Adhoc网络(MANET)是一种由无线移动主机/节点组成的动态自治网络。在MANET中进行有带宽保证的按需路由选择具有重要意义。本文提出一种新的按需路由算法LABGR(LocationAidedBandwidthGuaranteedRouting)。LABGR以节点当前位置信息为基础,在路由选择过程中把路径稳定性和节点能量受限问题结合起来,采用受限扩散路由方法,利用多种机制避免在全网中进行扩散,限制路由请求过程中被影响的节点数目,有效提高了路由请求效率并且保证了链路带宽。本文还对LABGR算法特性进行了深入分析。
Mobile Adhoc Network (MANET) is a dynamic autonomous network of wireless mobile hosts / nodes. Having bandwidth guaranteed on-demand routing in MANET is of great importance. This paper presents a new on-demand routing algorithm LABGR (LocationAidedBandwidthGuaranteedRouting). Based on the node’s current location information, LABGR combines the path stability with the limited node energy in the routing process. With limited diffusion routing method, LABGR uses multiple mechanisms to avoid spreading throughout the entire network and limits the routing request process In the affected node number, effectively improve the routing request efficiency and ensure the link bandwidth. In this paper, the characteristics of LABGR algorithm are further analyzed.
