Abstract

Mobile device’s networking capabilities offer opportunities for a new range of applications. We consider here a service that allows mobile users taking part in virtual meeting rooms to share information and documents. The sharing is promoted by a recommender system that assists users browsing documents, by making recommendations in the form of URLs pointing to other documents, that users in the virtual room have explicitly decided to share. A multi-user recommender system is a complex application requiring communication, memory and computing resources, and does not lend itself to a port to mobile devices with limited resources and intermittent connectivity. For this reason, we decided to offload the computationally intensive part of the application to the infrastructure, and to introduce the idea of an intermediary located in the network infrastructure, which interacts with applications on behalf of the mobile device, thereby hiding away the intermittent connectivity details. Our vision is that of a mobile intermediary, called Shadow, that will always be in close vicinity with the mobile device. We show that multiple Shadows may co-exist, and we propose a protocol capable of coordinating them. We present an abstraction layer, hiding away communication and coordination details, which offers a substrate for building the distributed recommender system across mobile devices and fixed infrastructure. Implementation details of our application are also presented.
