Mobile Web Services in Health Care and Sensor Networks

The Wireless Sensor Networks (WSN) environments are increasingly becoming intelligent with the rapid boost in the capabilities of sensor nodes. The Sun Small Programmable Object Technology (SPOT) platform offers a high-end sensing device in terms of processing, memory and battery configurations compared to other existing in the community. Within the scope of this paper, a health care use case is derived from the concept of service-oriented collector nodes represented by Sun SPOTs. The existing Mobile Web Services (MobWS) framework is ported to Sun SPOT devices that enables domain specific in-network computations enfolding synchronous or asynchronous classes of MobWSs. Based on that, the exemplary requirements of the Web Services (WS) in the health care domain are spotlighted and impressions of a comprehensive prototype, called MEDICARE, are shown.
