中文摘要：

针对干扰邻居数（INX）路由度量不能正确反映网络负载分布信息这一关键问题,在INX的基础上提出无线Mesh网络干扰与区域负载感知（IRLA）路由度量.IRLA通过平均竞争度描述干扰链路对同一信道的竞争程度和干扰链路负载的离散程度来衡量网络负载分布状况,使网络在路径选择时避开重负载区域,有效地实现了网络负载均衡.理论分析和NS-2仿真结果表明,所提路由度量能显著提高网络吞吐量,降低网络端到端时延和丢包率,在高负载网络环境下,仍具有提升网络性能的优势.

英文摘要：

Aiming at solving the problem that information about the distribution of network traffic load cannot be correctly captured by interferer neighbors count （INX） routing metric, an interference and re- gional load aware （IRLA） routing metric for wireless mesh networks was proposed. Average competition degree was used to describe the competition degree for the same channel among interferer links and the dispersion degree of traffic load on interferer links. The information was utilized to guide the routing se- lection for avoiding heavy traffic load regions and achieving network load balance effectively. Analysis and NS-2 simulation show that the proposed routing metric can not only improve network throughput dra- matically, but also reduce end to end delay and packet loss ratio, and it can even enhance the network performance in heavy load environment.
