The future of wireless networks evolves toward more simple ways for users to get connected while on the move. In this perspective, Wireless Mesh Networks constitute one of the key technologies for new generation wireless networks. In this paper we present a reactive solution for routing and client management in an infrastructure-based wireless mesh network. The solution is based on DYMO1/AODV adhoc routing protocol; it performs on-demand path setup for clients and supports their mobility by introducing a light mechanism. Our solution is designed to minimize memory and bandwidth overhead by exchanging only mandatory information for client management and route establishment
