Virtual socket interfaces for wireless network

The explosive popularity of wireless data networking has been continued over the years. Furthermore, the strong requirement to access the Internet while on the move via mobile devices is growing more and more, since lots of useful resources are residing in the wired net, Internet. DataTAC manufactured by Motorola Inc. provides an infrastructure bridging Internet and mobile devices. On top of it, we built a middleware to make it possible for existing network software to surf on the Internet with a mobile device. The middleware provides such high application transparency that it does not need to be recompiled to adapt the middleware. We call that system Brown (Bridge over wireless net to Internet). In this paper, we introduce Brown, and then addresses the core technology, Vision (Virtual socket interfaces over wireless net), a communication layer to support multiple TCP/IP socket-based communication channels
