Emerging communication-intensive applications require significant levels of networking resources for efficient operation. In the context of mobile computing environments, limited and dynamically varying available resources, stringent application requirements, and user mobility make it difficult to provide sustained quality of service to applications. This paper addresses the above issues, and proposes a new service model in cellular mobile computing environments. The major results of this paper are the following:

• An Adaptive Service model in mobile computing environments, which enables the network and applications to adaptively (re)negotiate QoS depending on dynamic network conditions
• An algorithmic framework that provides cost-effective resource adaptation in the presence of resource and network dynamics
• A …
