Resource and service registration and lookup in cooperating embedded systems

This paper investigates if service registration and lookup could become a usable component in future middlewares for cooperating embedded systems, e.g. wireless sensor networks and automotive networks. As a main part of this investigation, three different traditional middleware architectures have been investigated, focusing on how service registration and lookup is implemented in them. They are all targeted at a classical distributed computing environment – Jini, OSGi and UPnP. The possibilities for reuse of the architectural design patterns in middlewares for cooperating embedded systems is a keystone of the comparison. The main difference found between them was the degree of distribution – UPnP is totally distributed and Jini to some extent, while the OSGi specification does not take distributed applications into consideration at all.
