Abstract
Wireless mesh networks have been presented as a robust, scalable and low cost solution to provide connectivity in long distance areas. However, given its nature, routing strategies must support seamless mobility of nodes while enabling operation with a good performance and fast self-recovery from links fault. The routing approaches that meet these requirements are based on protocols usually used in ad-hoc networks (e.g. OLSR and B.A.T.M.A.N.) and, more recently, in the SDN paradigm (e.g. OpenWiMesh), each one of them having its own pros and cons. Therefore, it is important to evaluate the benefits and impacts of each approach, taking into account models and metrics inherent to the mobility. In this paper, we propose a simplified implementation of mobility support in OpenWiMesh and evaluate its performance compared to other protocols, using differents mobility and data traffic models.…
