Wireless Mesh Networks (WMN), a two-tier architecture§based on§Wireless Mesh Routers (WMR), has captured the§interest from both§academia and industry, because of their ability to§accommodate §both§Wireless ISPs and user requirements. Despite the§large amount of§research developed in this area, several issues still§need to be§solved. In this thesis we design an efficient§solution for multi-hop§wireless networks providing the following§contributions. First, we§design and formalize Mesh Routing Strategy (MRS), a§cross-layer§routing approach. MRS relies on simple heuristics§able to optimize§transmission power and route selection, resulting in§important§increase of the transport capacity of the mesh§backbone. Second, we§design and implement MeshDV, a routing framework§adapted to §WMNs,§which includes MRS and is also able to easily manage user§mobility. Third, we develop MeshDVbox, a custom WMR§built using§off-the-shelf components and deployed in our§laboratory to realize §a§WMN test-bed.
