Peer-to-Peer Remote Service Discovery in Pervasive Computing

Abstract

Service discovery is important in realizing the concept of pervasive computing; consequently, service discovery protocols must be able to work in the heterogeneous environment offered by this computing paradigm. Remote service discovery in particular has not been properly achieved so far. In an attempt to remedy this we propose a new architecture for enabling local service discovery mechanisms to discover services remotely. We first base our architecture on Universal Plug and Play (UPnP) as an example of local service discovery protocols, and Gnutella as an example of peer-to-peer distributed search protocols. We introduce a module called service mirror builder to the UPnP protocol, and a remote communication protocol over a Gnutella network. We then note that our architecture is actually independent on any locally deployed discovery protocol and thus supports full interoperability. © Springer-Verlag Berlin Heidelberg 2013.
