Abstract:Due to their self-healing and self-configuration capabilities, Wireless Mesh Networks present an interesting technology for a wide range of situations, including disaster recovery, emergency response and public safety applications.
However, Wireless Mesh Networks have significant performance limitations in terms of throughput and delay requirements. This is particularly the case for rapid deployment scenarios, where the deployment is unplanned and the network environment is often highly dynamic. The performance limitations are most severe for resource intensive applications such as video surveillance, which is increasingly vital in a wide range of safety and security scenarios.
This research tries to address these shortcomings by developing new routing metrics, that are able to consider a wide range of factors, such as interference, link load, congestion, node type etc.
For this, we analyse the state of the art in the field of routing in wireless mesh networks and construct a universal set of components from which routing metrics for these networks are formed. We then present a set of criteria which we utilise to compare existing works. This provides the basis for exploring the creation of a new routing metric to improve on existing works. Furthermore, we will also investigate the feasibility of dynamically adapting routing metrics parameters based on the network environment and usage patterns.
