PLASMADS: Smart mobiles meet intelligent environments

Pervasive connectivity over short-range RF technology will provide mobile devices access to interaction opportunities with people, services and contents, being offered by other nearby mobile devices as wen as by local bot spot infrastructures. Currently the mobile device is dumb and the infrastructure knows everything, or vice versa. Mobile devices sucb as PDAs and smart phones are becoming more and more powerful and bot spots provide more and more services. One of the major problems that have to be solved before real pervasiveness is achieved, is how to enable a specific mobile device to use services offered at a hot spot that bas Just been detected. With the variety of mobile devices, platforms, programming languages, operating systems etc. it is very likely that the mobile and the hot spot do not use the same components, i.e. they are not capable to cooperate. We present a system architecture and middlewarel for pervasive connectivity that is based on open standards such as UPnP and Web Services. Thus, it allows out of the box interaction between mobile devices, services and hot spot infrastructures.
