This paper presents a mobile host architecture based on how SOPHRA addresses the challenges of
resources state change management that arise from hosting services on mobile providers in unreliable
wireless networks. A middleware framework is employed on a private internal cloud to enable mobile
hosts to be reached via Wi-Fi by other health care professionals. The architectural design as illustrated in
Figure 2, is classified into three tiers namely: mobile service requesters, middleware, and mobile service
providers/hosts. The middleware is hosted on the cloud infrastructure and the mobile devices connect to
the middleware through 802.11g Wi-Fi 54Mbps connection. Also, the implementation took into account
both SOAP and RESTful paradigms of building Web Services (WS) for the purposes of evaluating the
performance of each WS.
