摘要
在基于HWMP路由协议的研究上,进一步提出一种面向无线Mesh网络的LB-IA-HWMP路由协议,该协议打破了以往单一路由判据的观念,采用了一种综合性的路由判据BPF(Best Path Finding),此路由判据综合考虑了节点的负载能力和处理能力以及链路的干扰程度,单一的路由判据在提高无线Mesh网络性能方面存有局限性问题,然而此协议可以很好地改良这一问题,为保证无线Mesh网络的正常运转,一定要尽力保证网络中节点之间流量的负载均衡且控制链路干扰的程度,因此该协议的采用能够在无线Mesh网络运行过程中大幅度的预防网络拥塞的产生和降低链路干扰.经过仿真与分析后,结果表明有效预防了网络运行过程中高负载区域的产生,充分利用了无线Mesh网络中节点之间的数据传输的链路资源,使得网络的整体性能得到了大幅度的提高.
On the research of HWMP routing protocol,a LB-IA-HWMP routing protocol for wireless Mesh network is further proposed.The protocol breaks the previous concept of single routing criterion and adopts a comprehensive routing criterion BPF(Best Path Finding).The load capacity and processing capacity of the node and the interference degree of the link are considered by the criterion.Single routing criterion has limitations in improving the performance of wireless Mesh network.However,this routing protocol can improve this problem very well.In order to guarantee the normal operation of wireless Mesh network,we must try our best to guarantee load balance between nodes in the network and control the degree of link interference.Therefore,the adoption of this protocol can greatly prevent the generation of network congestion and reduce link interference during the operation of wireless Mesh network.After simulation and analysis,the results show that it can effectively prevent the generation of high-load areas in the process of network operation,and make full use of the link resources of data transmission between nodes in wireless Mesh network,and greatly improve the overall performance of the network.
