Many industrial and medical scenarios today are building on mobile devices as their end systems. These devices are typically connected to backend systems via the mobile phone network with their corresponding data services. Today's network protocols are optimized for reliable transfer of voice traffic, however, available bandwidth and latency for data traffic may vary significantly with location and...
Mobile devices like PDAs or mobile phones have become widespread. Similarly network functionality like GSM, Bluetooth or WLAN has become a standard. Nevertheless, not many applications take mobility into account. An application and its communication component are tightly coupled and the application assumes that network behavior does not change. Here in this paper we propose a new lightweight architecture...
In recent years, integrating SIP with OSGi has become one of the important research topics in the communication between mobile and networked home devices. In this paper, the general architecture for combining OSGi and SIP is investigated and implementation issues with the communication middleware are discussed. The encapsulation of OSGi devices with SIP has been realized by the concept of "SIP...
