چکیده

Object-Z is strong in modeling the data and operations of complex systems. However, it is weak in specifying real-time and concurrent systems. The Timed Communicating Object-Z (TCOZ) extends Object-Z notation with Timed CSP's constructs. TCOZ is particularly well suited for specifying complex systems whose components have their own thread of control. This paper demonstrates expressiveness of the TCOZ notation through a case study on specifying a multi-lift system that operates in real-time.

Timed Patterns: TCOZ to Timed Automata

The integrated logic-based modeling language, Timed Communicating Object Z (TCOZ), is well suited for presenting complete and coherent requirement models for complex real-time systems. However, the challenge is how to verify the TCOZ models with tool support, especially for analyzing timing properties. Specialized graph-based modeling technique, Timed Automata (TA), has powerful mechanisms for ...

Multi-layer Clustering Topology Design in Densely Deployed Wireless Sensor Network using Evolutionary Algorithms

Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...

Multi-agent System Specification Using TCOZ

TCOZ is a specification language that combines the strengths of Object-Z and Timed CSP with the goal of specifying distributed systems containing objects that act independently and concurrently. Such goals are similar to the goals of the autonomous agent paradigm, in which agents are entities in an environment that act independently of one another, concurrently, and work proactively to achieve ...

Topology Control in Wireless Sensor Network using Fuzzy Logic

Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, the use oftopology control is required to decrease power consumption and increase network acce...

TAC: A Topology-Aware Chord-based Peer-to-Peer Network

Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...
