Data aggregation is a very important method to conserve energy by eliminating the inherent redundancy of raw(More)
Actor-based modeling has been successfully applied to the representation of concurrent and distributed systems. Besides having an appropriate and efficient way for modeling these systems, one needs a formal verification approach for ensuring their correctness. In this paper, we develop an actor-based model for describing such systems, use temporal logic to(More)
The rapid proliferation of computer networks has changed the prospect of network security. An easy accessibility condition cause computer networkpsilas vulnerable against several threats from hackers. Threats to networks are numerous and potentially devastating. Up to the moment, researchers have developed Intrusion Detection Systems (IDS) capable of(More)
We present a process algebra for modeling and reasoning about Mobile Ad hoc Networks (MANETs) and their protocols. In our algebra we model the essential modeling concepts of ad hoc networks, i.e. local broadcast, connectivity of nodes and connectivity changes. Connectivity and connectivity changes are modeled implicitly in the semantics, which results in a(More)
Rebeca is an actor-based language with formal semantics that can be used in modeling concurrent and distributed software and protocols. Automatic verification of these systems in the design stage helps develop error free systems. In this paper, we describe the model checking tool developed for verification of Rebeca models. This tool uses partial order(More)
The increasing demand on execution of large-scale Cloud workflow applications which need a robust and elastic computing infrastructure usually lead to the use of high-performance Grid computing clusters. As the owners of Cloud applications expect to fulfill the requested Quality of Services (QoS) by the Grid environment, an adaptive scheduling mechanism is(More)
Secure routing is one of the most important topics in the wireless MANETs networks. MANETs networks don't have a central infrastructure for the management of routing in the networks. Each node independently routes and sends packets, so many attacks such as forging, modifying, and denial of service (DoS), Occur in these networks. In this paper, we present(More)
