摘要： 提出了无线Mesh网络负载与干扰感知传输时间LIATT(Load and interference-aware transmission time)路由度量，有效继承了CATT(Contention aware transmission time)和INX(Interferer neighbors count)路由度量统一描述流内和流间干扰的优势。LIATT使用节点处的缓存队列长度捕捉负载，使用邻区平均负载强度捕捉干扰，实现有效的网络负载均衡与干扰感知，避免将数据包路由到网络负载和干扰较重区域而导致拥塞的问题。利用NS-2仿真软件进行的性能评价表明:本文路由度量能有效实现网络负载均衡，提升网络整体性能。

Abstract: A Load and Interference-Aware Transmission Time (LIATT) routing metric is proposed. It inherits the advantage of describing intra-flow and inter-flow interference uniformly. The buffer queue length of node is used to capture traffic load, and the average load of adjacent areas is used to capture interference, thus, achieving the load-balancing function and interference-aware function, which can avoid routing packets into heavy load and intense interference area. Simulation with NS-2 software is carried out to evaluate the performance of the proposed LIATT routing metric. Results show that the LIATT routing metric can effectively achieve load balancing and improve the whole network performance.
