Performance Analysis of Nomadic Mobile Services on Multi-homed Handheld 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
