Abstract
Wireless Mesh Networks (WMNs) are emerging as future-generation technologies for back-haul connectivity of different types of networks. They are multi-hop networks consisting of mesh nodes, mesh clients and mesh routers. To achieve high performance, these networks use Multi-Channel Multiple Radio (MCMR) capabilities of mesh routers. However, QoS degrades due to the introduction of inter-flow interference and intra-flow interference by these nodes. Thus, there is a need to design a routing protocol that considers interference in the network. Furthermore, as the traditional approaches of protocol design lacks in improving QoS, the cross-layer metrics are designed by using the information from physical, MAC and network layer. In this paper, we investigated and analysed the performance of multi-radio cross-layer routing metrics. We performed extensive quantitative analysis in NS-2 using OLSR protocol. The performance differentials and trade-off analysis is carried out using five QoS parameters.
