Abstract

Mobile computing environments are characterized by heterogeneity—systems consisting of different device types, operating systems, network interfaces, and communication protocols. In a realistic scenario of context-aware computing, we should be able to deploy context management middleware throughout the distributed system at every device, despite its resource limitations, and the developer should be able to evolve the context model whenever new context-aware applications or context providers are introduced. This article presents a middleware architecture and design strategies that address these requirements without compromising efficiency.
