Despite current 802.11i security protocol, wireless networks are vulnerable to Denial of Service (DoS) attacks. Sending a continuous stream of forgery control frames by an attacker can easily flood wireless channel so that the network cannot be available for its associated users. These attacks are possible because wireless control frames do not carry any cryptographic mechanism to detect and di...

As traffic patterns and network topologies become more and more complicated in current enterprise data centers and TOP500 supercomputers, the probability of network congestion increases. If no countermeasures are taken, network congestion causes long communication delays and degrades network performance. A congestion control mechanism is often provided to reduce the consequences of congestion. ...

This paper proposes a novel simulation framework designed to assess the performance of wireless cognitive networks in realistic scenarios. The simulation framework is based on the combination of the OMNeT++ discrete event simulator with Matlab functionalities. The popular INET simulation package for OMNeT++ is extended with the introduction of cognitive functionalities and integrated with a mor...

The evolution of cellular technologies toward 5G progressively enables efficient and ubiquitous communications in an increasing number of fields. Among these, vehicular networks are being considered as one of the most promising and challenging applications, requiring support for communications in high-speed mobility and delay-constrained information exchange in proximity. In this context, simul...

Routing and switching capabilities of computer networks seem as the closed environment containing a limited set of deployed protocols, which nobody dares to change. The majority of wired network designs are stuck with OSPF (guaranteeing dynamic routing exchange on network layer) and RSTP (securing loop-free data-link layer topology). Recently, more use-case specific routing protocols, such as B...

This paper addresses the need to analyze and validate the architectural requirements of complex systems-of-systems early in the development process. We present an iterative rapid prototyping process for studying the temporal behavior of the system-of-systems architecture via object-oriented architectural models expressed in UML-RT (UML for Real-Time extension) augmented with formal specificatio...

This paper describes a framework for simulating opportunistic routing protocols in the INETMANET framework of OMNeT++. The proposed modules adopt an abstraction of the generic functions of the most representative opportunistic routing algorithms. The main contribution is an OMNeT++ modeling architecture that could be extended to implement different opportunistic routing schemes. Our work provid...

In this work, we will give a detailed tutorial instruction about how to use the Mobile Multi-Media Wireless Sensor Networks (M3WSN) simulation framework. The M3WSN framework has been published as a scientific paper in the 6th International Workshop on OMNeT++ (2013) [1]. M3WSN framework enables the multimedia transmission of real video sequence. Therefore, a set of multimedia algorithms, protoc...
