Redesign and optimalization of the Peer2Me Framework: A Framework for developing Applications supporting mobile collaboration using J2ME

Abstract

This project was started to develop a new improved version of the Peer2Me framework. After having evaluated the first version of the Peer2Me framework in our depth study project in the fall of 2005, quite a few possible improvements came up. This report starts with an introduction to Computer Supported Cooperative Work (CSCW), wireless networking, Peer-to-Peer (P2P) computing, and mobile ad hoc networking. It also introduces some central concepts concerning design of a software architecture, and technology relevant to the development of the Peer2Me framework. The redesign of the framework was started by eliciting a set of new requirements, constituting the basis for designing the new Peer2Me architecture. Through an iterative and incremental development process, Peer2Me framework v2.0 was developed with several new features. An instant messenger application has been developed using both versions of the framework, in order to compare them. A thorough comparison of Peer2Me v1.0 and Peer2Me v2.0 shows that the redesign has resulted in a reduced framework footprint and complexity, a simplified interface towards the MIDlets, and a considerably increase in transfer rate.
