Decentralized querying of topological relations between regions without using localization

Duckham, Matt; Jeong, Myeong Hun; Li, Sanjiang; Renz, Jochen


This paper proposes an efficient, decentralized algorithm for determining the topological relationship between two regions monitored by a geosensor network. Many centralized algorithms already exist for this purpose (used for example in spatial databases). However, these algorithms are not suited to decentralized spatial computing environments, like geosensor networks, which must operate without global knowledge of the system state and without centralized control. Unlike many existing...[Show more]
