Delaunay overlay networks have a Delaunay graph structure, which has spatial locality. This feature is useful for distributed spatial computing, distributed geographical database systems, and geometric routing networks. An incremental construction method of these networks is proposed. The existing method assumes that each communication node can create overlay connections using IDs with all other nodes...
Researches on computing an optimal route according to user's preference or spatial contexts have been gaining focus recently, as car navigation and pedestrian navigation systems are getting accustomed to be used in daily lives. In this paper, the authors propose a method to compute a path to pass through as many context areas as possible along its route, according to the user's needs. Specifically,...
