Usage-aware search in Peer-to-Peer systems

Abstract

We study solutions to a source discovery problem defined in the framework of providing time-critical context-aware services over a Peer-to-Peer communication paradigm. The proposed mechanisms, which take place in ubiquitous computing environments, exploit the locality of reference properties exhibited by context usage patterns, with efficient means provided by Active Networks. Simulation results show that the new methods reduce network traffic while they maintain the good search time of flood broadcasting methods. © IFIP International Federation for Information Processing 2007.
