Abstract—Web services are going mobile. A Mobile Enter-prise can be established in a cellular network by participating Mobile Hosts, which act as web service providers, and their clients. Mobile Hosts enable seamless integration of user-specific services to the enterprise, by following web service standards, also on the radio link and via resource constrained smart phones. However, establishing such a Mobile Enterprise poses several technical challenges, like the quality of service (QoS) and discovery aspects, for the network and as well as for mobile phone users. The paper summarizes the challenges and research in this domain, along with our developed mobile web service mediation framework (MWSMF). However, to scale Mobile Enterprise to the loads possible in cellular networks, we shifted some of its components to the new utility computing paradigm, cloud computing. The cloud based load balancing for the Mobile Enterprise can be provided at the middleware framework level or at the individual services level. This paper described both the approaches, with two Mobile Host appli-cation scenarios, in collaborative m-learning and multimedia services domains. The analysis concludes that MWSMF and its components are horizontally scalable, thus allowing to utilize elasticity of cloud platform to meet load requirements of Mobile Enterprise in an easy and quick manner.
