UDIO: An ubiquitous device inter-operation system based on IGRS

To address the problem of service composition in pervasive computing, and to provide the IGRS ubiquitous devices the abilities of inter-operation and cooperation, we design the UDIO, a middleware of dynamic service composition based on IGRS protocol. In this paper, the system architecture of UIDO, as well as a matrix-based path-finding algorithm for service composition, are introduced which prove to be available and efficient in our IGRS smart home. © 2010 IEEE.
