An Analysis of Routing Protocol Metrics in Wireless Mesh Networks

Wireless Mesh Networks (WMN)s play an important role in todays communication and they are expected to increase in proliferation in the field of wireless communication in the near future. Researchers in the area of WMNs address some issues like low throughput and high latency. Routing Protocols in WMNs have a vital role in data communication and the key parameter in all routing protocols is link metrics. In this paper the majority of link metrics in WMNs are studied in different categories. Link-quality and traffic-aware metrics account for most of the metrics, however multi channel network and cognitive radio systems are also considered in detail. In each section, by reviewing the metrics and its performance in detail, summary and comparison tables of link quality metrics are also provided to enable better understanding of this topic.
