The results of simulation of popular routing protocols in DTN wireless networks with the hybrid mobility model of DTN’s nodes are presented. The purpose was to evaluate the message delivery probability and the average time of message delivery. The simulation model is implemented in the OMNeT ++ simulation system. From the simulation experiments it has been found that the daily periodic repeatab...

The paper describes the agent-based approach and software environment (based on OMNeT++ INET Framework) developed for simulation of distributed defense mechanisms which can be deployed in the Internet for counteraction to computer network attacks. According to the approach suggested, the cybernetic counteraction of “bad guys” and security systems is represented by the interaction of different a...

The scalability and flexibility of wireless networks are the basis of the growing success of Wireless Networked Control Systems (WNCSs). Both the HART Communication Foundation and the ISA association have recently proposed their own standard for a wireless fieldbus (WirelessHART ratified in 2007, and ISA100.11a ratified in 2009, respectively). However, WNCSs performances are hard to verify in t...

This work presents operation and the results obtained in an information-centric multiaccess content distribution prototype using both real laboratory environment tests and simulation experiments with OMNeT++. We present the basic objectives and mechanisms of our solution and evaluate it against a standard BitTorrent. The results show that our prototype based on an information-centric approach c...

The paper presents a comparative analysis of reallocation algorithms in a structure of wireless sensor network in the event of a failure of network nodes. The article contains detailed research results of wireless sensor networks technology, with particular emphasis on thte network-layer protocols routing protocols. In the research the simulation environment OMNeT++ was used to study the proper...

In this paper, we present a concept for an aeronautical communications simulator based on the discrete event simulation platform OMNeT++. In the aeronautical environment, there is a mutual dependency between the movement of the aircraft and the data traffic that is generated, making an accurate modeling particularly difficult. In addition, such a simulator requires a modular architecture due to...

This paper describes the implementation in OMNeT++ of a versatile protocol architecture for the simulation of 802.11 Wireless Mesh Networks (WMNs). The developed modules enable the routing at the 802.11 MAC layer as well as a packet forwarding technique based on label paths. The performance of the new architecture is compared with that of a typical IP OLSR ad hoc network proving that link layer...

This technical report outlines techniques and theories of generating live and simulating first person shooter game traffic for N specific players. We outline a two approaches. Firstly creating live network traffic using a tool called pktgen. Secondly we outline how to simulate using Omnet Network simulator and Network Simulator with a C library called ‘ArmaPktLen’. All approaches use a combinat...
