Abstract: Existing tuple-based middleware-level mechanisms often use broadcasting for resource discovery in pervasive systems. We present a new routing-aware mechanism based on S2P networks. Each peer has a routing table containing information on the peers that most recently have provided this peer| requested resources. Each peer caches and uses such information to route its requests peer to peer. We implemented our routing mechanism in Java and ran it on a prototyped system under LIME in a MANET. The results demonstrated approximately 53% improvement in the query processing response time of the constructed pervasive system compared to the response time of the same system running a default routing mechanism in LIME.

Keywords: pervasive systems; routing middleware; tuple space; social peer to peer networks; S2P networks; resource discovery; routing awareness; query processing.
