WIPdroid – A Two-way Web Services and Real-time Communication Enabled Mobile Computing Platform for Distributed Services Computing

We present a mobile distributed computing platform, WIPdroid, for distributed services computing in mobile environment with real-time communication capabilities. It is based on WIP, Web services session initiation protocol, for real-time service-oriented communication over IP. It integrates the emerging mobile endpoint platform, Android, from Google´s initiative of open handset alliance (OHA). The WIP component of WIPdroid supports Web services based communication over IP. But most importantly, it transforms WIPdroid into a mobile SOA Web services endpoint. Applications developed on WIPdroid can be exposed and enabled by two-way Web services. This makes WIPdroid well suited for distributed computing and SOA based applications, such as communication enabled business process (CEBP) and software-as-a-service (SaaS). It also leads to a new type of dual-mode phone, with one communication mode from the binding with the physical mobile environment, e.g. GSM, CDMA, 3G, etc., and one fully web services enabled, service-oriented communication over IP mode from WIP. A prototype WIPdroid mobile computing platform is developed and tested. In order to support advance Web services capabilities on mobile endpoints, we developed an endpoint-edition of two-way Web services application proxy (2SAP) which has a small memory footprint (2-3 MB) and can be hosted on a mobile endpoint/handset, e.g. smart phone and PDA.
