The focus of existing virtual communities is centered on a particular product or social interaction and the role of mobile devices is restricted to exchange a limited amount of contents. Herewith we envisage that the upcoming virtual communities will exploit the potential of social interaction and context information to offer personalized services to its members and mobile devices will play a significant role in this process. As a step towards this direction, in this paper we propose a business model for the mobile virtual communities in which the mobile device takes on the role of a content producer and content consumer. Though there are a number of research issues which need to be addressed to realize such virtual communities, in this paper we focus on the service requirements, architecture and open source software implementation of a technical platform for the content producer and consumer mobile devices.

Compared to their predecessors, the current generation handheld mobile devices possess higher processing power, increased memory and new multi-homing capabilities. These features combined with the widespread acceptance and use of these devices result in a situation where mobile devices are no longer merely data consumers, but also able to act as data producers. Nomadic mobile services make this data available to the clients on the Internet and the contextawareness provides the capability to the nomadic mobile services to select suitable interface for data transfer. In this paper, we conduct a performance analysis of nomadic mobile services prototyped in the remote patient tele-monitoring domain and hosted on a multi-homed handheld mobile device. The experimentation aims at analyzing the suitability of a particular network for the data transfer, the effect of multi-homing on the remote patient tele-monitoring application and the resource utilization on the mobile device. The performance analysis provides us useful insights, which will be exploited in future work regarding policy based network interface selection mechanisms for nomadic mobile services.

In today's world of pervasive computing, the mobile devices are enriched with a variety of features and being used as a personal information delivery platform. The increased processing, storage and communication capabilities of these devices combined with the latest developments in the area of service oriented architecture enables a new class of services, called nomadic mobile services (NMS). Recent research has resulted in different NMS provisioning approaches; each one employs/defines a different architecture and addresses a different mix of issues. This paper provides a comparative study of three NMS provisioning approaches based on their architectural design, development choices and prototyped applications. Each approach has its own merits considering the applications they aim at. However, in the future, a solution which uses Web services for better interoperability and employs proxy approach for better QoS could be a possible technical design.
