T popularity of reconfigurable radios is increasing as wireless infrastructure equipment manufacturers try to design platforms that cover multiple frequencies and air interfaces. The market continues to strive to achieve the ideal of a softwaredefined radio (SDR). While this research continues, incremental developments are taking place that provide common platform designs. Designs are then conf...

Concurrency in object-oriented languages is still waiting for a satisfactory solution. For many application areas, standard mechanisms like threads and locks are too low level and have shown to be error-prone and not modular enough. Lately the actor paradigm has regained attention as a possible solution to concurrency in OOLs. We propose JCoBox: a Java extension with an actor-like concurrency m...

Active and programmable network technologies strive to support completely new forms of data-path processing capabilities inside the network. This in conjunction with the ability to dynamically deploy such active services at strategic locations inside the network enables totally new types of applications. In this paper we exploit these network-side programming capabilities to realise a new activ...
