ABSTRACT
Software systems that execute in embedded and pervasive environments are frequently required to be self-monitoring, self-adapting, and self-healing. However, supporting these self-* capabilities in pervasive environments creates a number of unique engineering challenges. This paper first describes the challenges that we believe to be the most significant based on our experience developing real-world pervasive software applications with self-* capabilities. We then discuss each challenge in the context of four strategies commonly employed in self-* systems: dynamic software update, service discovery, transparent replication, and logical mobility. Finally, we explain how each strategy is implemented in our architectural middleware platform, Prism-MW.

Schizophrenic middleware support for fault tolerance
SIGAda '06: Proceedings of the 2006 annual ACM SIGAda international conference on AdaIn this paper, we identify the middleware functionnalities andproperties that are required to efficiently implement the FaultTolerant CORBA specification.

A framework for architecting and high-level programming support of CORBA applications
Special issue on middlewareIn this paper, we present a framework, called <i>OrbGOP</i>, to support the architecting and high-level programming of CORBA-based distributed applications. OrbGOP makes two contributions to the development of CORBA applications: (1) it provides higher-...
