An Implementation Of Cyber Foraging: Access To Smart Space By Mobile Phone

As the development of computing and communication, mobile phone with communication and computing capability will become ubiquitous. They will provide convenience service for everyone, but people have to face the capacity limitation of their mobile phone. Ubiquitous computing is a new generation of computer after workstation and desktop computer. It's most important character are highly integrated and interaction. Smart space is concentration of these two characters of ubiquitous computer. It is an environment that integrates computing, communication and awareness capability. Ubiquitous computing is target to let anyone to access information anytime, anywhere. Cyber foraging is an important function of smart space that can help people using service form environment. How to augment the capability of handheld mobile device by adopting the resources in the environment absorbs a lot of research interest. This thesis gives a new application model of mobile phone in the smart space computing environment, discusses some key technologies and describes an architecture supporting the application mode. It is an implementation of cyber foraging supporting access Smart Space by mobile phone. To meet this challenge, we should first consider is Service Discovery. User will like to know what services in this Smart Space. We introduce the Service Discover Protocol and design a so called "Pull" Man Machine Interface for accomplishing Service Discovery. Base on Service Discovery, in thesis, we still have the Service Invocation issue. We implement the Service Invocation framework by using GPRS and J2ME. Considering that combining mobile phone with Smart Space is cross-platform, for handling of application usability, it is critical to develop consistent UI of mobile phone. Solutions to UI are also discussed in the thesis.
