Mesh Overlay for wM-Bus Network

In the context of smart cities, connecting devices in the urban environmet present not few difficulties in terms of obstacles to propagation. On top of already defined and certified protocols, such as wM-Bus, which still holds its position and usability, new services are developed for the energy-saving purpose of giving the citizen new comforts and new interactions with the urban environment. In this article, an overlay protocol to a wM-Bus wireless network for smart lighting is presented. The proposed method uses the existing wM-Bus network layer to reach high distances and mesh operation to overcome the topological difficulties introduced by the city obstacles. The protocol description, simulation and experimentation phases are presented.
