In this paper we present a software tool for the simulation of distributed real-time embedded systems. Our tool is based on the popular NS-2 package for simulating the networking ...
The paper targets the applicability of model-driven methodologies to the validation of complex systems and presents a case study of a mobile radio network. Validation relies on the...
Replication is a well-know fault-tolerance technique, and several replication strategies exist (e.g. active, passive, and semi-active replication). To be used in hard real-time sy...
The ability of worms to spread at rates that effectively preclude human-directed reaction has elevated them to a first-class security threat to distributed systems. We present th...
This paper studies the performance of a multi-rate mobile ad hoc network (MANET) using an extended ns-2 simulator. A link adaptation algorithm is developed and tested. The multi-r...
