Load balancing routing and quality of transmission (QoT) aware routing have been increasingly studied in mesh wireless networks (WMN) to improve their performance. For the load balancing routing, the traffic bottleneck in the network can be resolved. However, it can decrease QoT because the routes may passthrough multiple hops. On the other hand, the QoT aware routing often improves the QoT of the routes, but it can increase thetraffic bottleneck due to the unbalanced traffic load in the network. Therefore, the investigation of load balancing routing taking into account QoT is very essential, especially in the case of a wideand ultra-high speed WMN. In this paper, we propose a load balancing routing algorithm under the constraints of QoT for WMN. Our method uses the principle of the software defined networking (SDN) to choose the load balancing routes satisfying the constraints of QoT. Our performance evaluations using OMNeT+ have shownthe effectiveness of the proposed algorithm in improving QoT of thedata transmission routes, increasing the packet delivery ratio andthe network throughput, decreasing the end-to-end delay.

基于软件定义网络的网状无线网络中传输质量约束下的负载均衡路由

在网状无线网络（WMN）中，越来越多地研究负载平衡路由和传输质量（QoT）感知路由，以提高其性能。对于负载均衡路由，可以解决网络中的流量瓶颈。但是，由于路由可能会经过多个跃点，因此会降低QoT。另一方面，基于QoT的路由通常可以提高路由的QoT，但是由于网络中的流量负载不平衡，它可能会增加流量瓶颈。因此，考虑到QoT的负载均衡路由研究非常必要，尤其是在宽而超高速WMN的情况下。在本文中，我们提出了一种在QoT约束下的WMN负载均衡路由算法。我们的方法使用软件定义网络（SDN）的原理来选择满足QoT约束的负载均衡路由。我们使用OMNeT +进行的性能评估表明，该算法在改善数据传输路径的QoT，提高数据包传输率和网络吞吐量，减少端到端延迟方面是有效的。
