Mobile services over short range communication

pcoming mobile devices capable of using multiple access networks require new approaches to build up distributed computing networks. It is a challenge to provide seamless and interesting services with these heterogeneous infrastructures. Therefore we analyze different access networks and focus on short range communication based on Bluetooth. On the basis of a typical scenario we have done some research on selected aspects of services in mobile networks. The concept of services becomes especially interesting in conjunction with Java equipped smart phones. Research revealed the necessity of a framework managing content and dynamic adaptation to changing network conditions.
