Semantic P2P Overlay for Dynamic Context Lookup
(2010) The Fourth International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies (UBICOMM 2010) p.464-470- Abstract
- Context-aware applications generally need to retrieve various kinds of dynamic context data from a large number of context sources. A middleware managing context sources must provide an efficient context lookup mechanism to ease application development. In this paper, we categorize the context sources as operating spaces and propose semantic peer-to-peer overlays over these spaces to accelerate dynamic context lookup in a context-aware middleware. Our proposed overlay structure is specially designed to deal with dynamic sensory context such as a person’s location and temperature that are frequently changing and difficult to be promptly retrieved using traditional peer-to-peer protocols. Our overlay and indexing method has a low maintenance... (More)

Our overlay and indexing method has a low maintenance overhead. Measurement results show that the proposed overlay achieves a good response time and accuracy for context lookup as well as requires low maintenance overhead. (Less)
