A network service framework for mobile pervasive computing

In this paper, we propose a framework for wireless/mobile pervasive computing to augment capabilities and to save scanty resources of mobile host by making full use of available resources in the surrounding. Firstly, a mobile device finds and utilizes the cheap computer as a surrogate to forward the service requests. Secondly, after the surrogate discovers the services, it will filter, synthesize or handoff them according to the context information. We also take consideration of robustness, scalability, and load balancing by utilizing multi surrogates. Service descriptions are encoded by the extensible markup language (XML) technology to provide flexibility. The analytical results on the performance of our framework show that it has significant advantages in terms of reducing wireless bandwidth consumption, ant etc.
