无线Mesh网中基于负载平衡的多路径路由协议

Load Balancing Multipath Routing Protocol In Wireless Mesh Networks

由于现有针对AdHoc网络的路由协议难以满足WMN对多路径路由的要求,本文基于AOMDV协议针对WMN开发了一种基于拥塞感知的多路径路由协议MPR。首先设计了能够快速建立多条路径的路由发现机制,并根据多条路径的负载,通过计算链路的可得带宽给出了一种路径的拥塞感知机制,使得Mesh节点能够自适应选择多条路径以避免拥塞。仿真结果表明,该路由机制能够有效提升网络性能,同时对于有效降低丢包率。

Existing routing scheme in Ad hoc networks can not work efficiently in wireless mesh networks because the resource restricts for multipath. In this paper, we developed a congestion-aware multipath routing protocol （MPR） for wireless mesh network. At first, we design and implement a routing discovery scheme to establish multipath, based on the load of each paths, the available bandwidth of each path in multipath can be obtained, which can used for path selection when the congestions occurred. Simulation results show improved performance of network transmissions in terms of packet loss.
