m-NewsBoard: A News Dissemination Service for Mobile Users

The limitations of traditional pull-based Web services become significant to users who depend on timely and up-to-date information. Users are forced to frequently check the data of interest, or use clients which pull for data at regular intervals in search of changes. Such solutions can consume resources extensively: They are inadequate for environments with wireless bandwidth limitations. Push-based active dissemination of published content to interested users has recently been proposed as a viable alternative. This approach is based on the publish/subscribe (P/S) interaction model. In this paper we present the architecture and discuss the initial prototype implementation of m-NewsBoard, a P/S-based news dissemination service for mobile users. This service enables mobile users to browse the repository of current news, to publish additional news, and to receive notifications with news of their interest. The service architecture comprises loosely coupled components: a WAP-enabled Web interface, and a dissemination component providing different transportation mechanisms for content publishing, such as mail, SMS, or P/S-based content dissemination. The paper presents the initial m-NewsBoard's implementation and discusses our experiences related to the development of services for mobile users.
