Delay-aware Load Balanced Routing Protocol for IEEE 802.16 Wireless Mesh Networks
In IEEE 802.16 Wireless Mesh Networks (WMN) routing, delay aware load balancing can be achieved by selecting the shortest path with low latency and network load. But network load and latency together are not considered in most of the existing routing metrics. Here, the authors propose a delay aware load balanced routing protocol for wireless mesh networks by designing a combined route metric. Initially, they calculate the Metric of Traffic Interference (TIM) which considers the traffic load of interfering neighbors. Next, they calculate the Metric for End to end service Delay (EDM) by using the expected time spent in transmitting all packets waiting for transmission through a link.
