An Approach to Developing Information Dissemination Service for Ubiquitous Computing Applications

In many ubiquitous computing (ubicomp) applications, such as smart classrooms, hospitals, construction sites, stadiums, shopping malls, emergency set-vices, law enforcement, convention centers, battlefields, and inhospitable physical environments, an information dissemination service is needed for distributing information from one or more devices to a large number of devices. These systems normally possess the characteristics of autonomous decentralized systems (ADS). Information dissemination for ubicomp applications can be achieved by autonomous coordination, but complex interactions and autonomous coordination of these devices depend upon local and neighboring context and/or situation. Due to the mobility of the devices, unknown destinations for information from a source, and low computational power of the devices for routing, it is difficult to provide an information dissemination service for ubicomp applications. Reconfigurable context sensitive middleware (RCSM) has been used for ADS applications in ubicomp environments since it can provide context-sensitivity, situation-awareness, ad hoc communication and ADS properties. In this paper, an approach to developing an information dissemination service for ubicomp applications, which can be incorporated in RCSM, is presented
