Abstract : In this paper, we consider spontaneous wireless mesh networks that can provide wide coverage connectivity to mobile nodes. Our mobility scheme builds upon separation between a persistent node identifier and its current address. When joining the mesh, a mobile node associates with a mesh router that updates a location service managed in the mesh as a distributed hash table. Mobility implies changing addresses while a node moves in the mesh. To keep the rate of location updates and correspondent node notifications low, the address of the new mesh router with which the mobile node is associated needs to be topologically close to the previous one. Thus, such a mobility scheme requires an addressing space with specific properties. We achieve this by defining an algorithm for constructing a pseudo-geographical addressing space: a few nodes know their exact locations and others estimate their relative positions to form a topologically consistent addressing space. Such an addressing space also enables scalable and low overhead routing in the wireless mesh―we propose a tra jectory based long distance ballistic geographical routing. Coordinate addressing space, geographical routing.
