Smart phones have pervaded almost all the environments where people perform their day-to-day activities. They are now equipped with embedded sensors, camera, touchscreen, more memory and processing capabilities as well as efficient power saving mechanisms. Together, these improvements enable the mobile devices to perform tasks that are normally run in personal computers like the provisioning of services to other devices. The idea of Mobile Host is not new and this paper tries to extend the research in the domain to the current generation platforms, technologies and standards such as Android OS, Open Services Gateway initiative framework, Zero Conf and Representational State Transfer. While the services provided from Mobile Host like the push notification mechanism and the feasible applications are interesting, for successful adoption of the technology, we need to provide better discovery mechanisms for the offered services. Mobile web service (MWS) discovery is highly dependent on the size of the network and the mobility of the nodes. A peer-to-peer based solution is proposed for the MWS discovery, to avoid the troubles with centralized registries. The approach is discussed thoroughly along with the extensions in semantic discovery support and overlay support discovery mechanism for small networks with low mobility using ZeroConf.
