A Comparative Study of Nomadic Mobile Service Provisioning Approaches

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.
