Efficient Data Structure for Fully Symbolic Verification of Real-Time Software Systems
A new data-structure called RED (Region-Encoding Diagram) for the fully symbolic model-checking of real-time software systems is proposed. RED is a BDD-like data-structure for the encoding of regions [2]. Unlike ...

Timed Automata with Asynchronous Processes: Schedulability and Decidability
In this paper, we exend timed automata with asynchronous processes i.e. tasks triggered by events as a model for real-time systems. The model is expressive enough to describe concurrency and synchronization, a...

Schedulability Analysis Using Two Clocks
In classic scheduling theory, real-time tasks are usually assumed to be periodic, i.e. tasks arrive and compute with fixed rates periodically. To relax the stringent constraints on task arrival times, we propo...

Sensors Network Optimization by a Novel Genetic Algorithm
This paper describes the optimization of a sensor network by a novel Genetic Algorithm (GA) that we call King Mutation C2. For a given distribution of sensors, the goal of the system is to determine the optima...
