Abstract

Wireless Mesh Networks (WMN) is a popular communication paradigm due to its low cost and rapid deployment. A large-scale WMN needs a look-up structure to support storage, client mobility and generic services. A Distributed Hash Table (DHTs) spreads construction and maintenance load of abstract index infrastructure over participating nodes, providing simple data access interface. This study proposes a Mesh-DHT as a concept exploiting nodes physical locality to construct an overlay routing geometry using node identifiers reflecting wireless neighbor relations. As WMN s Quality of Service (QoS) parameters are Non-Deterministic Polynomial (NP) hard problem, we propose to use Particle Swarm Optimization (PSO) to identify best solution. A location aware Chord protocol is proposed to incorporate nodes locality in DHT construction.
