This paper reports on our experience in using OMNeT++ to develop a network simulator focused on railway environments. Common design problems are analyzed, making emphasis on radio communication models. Scalability issues are raised when modeling the large topologies that are associated with railway communications. Our conclusions point out that model reusability must be reinforced and that a co...

This research statement describes the author’s PhD project, which targets the evaluation of sensor network designs in realistic environments. Network emulation includes a variety of methods and strategies for the evaluation of system designs for networked systems in safe testing environments. The author’s interest is to bridge the gap between generic simulation environments and real sensor netw...

Due to the complex nature of computer and telecommunication networks, it is often difficult to predict the impact of different parameters on system performance especially when deploying wireless networks. Computer simulation has become a popular methodology for performance study of computer and telecommunication networks. This popularity results from the availability of various sophisticated an...

This paper presents an interference model of overlapping radio channels which allocate the same frequency band. The model is based on the INET Framework [12] of OMNeT++ [11] simulation engine and the raytracing tool Radiowave Propagation Simulator (RPS) [14]. By using our prediction model, we present a proposal for an easier integration of adaptive bit rate adjustment for wireless networks in O...

In order to observe the behaviour of a protocol in various scenarios, network simulators are used. There are few network simulators available for usage but which one will provide optimum performance and suitability of network simulator for a particular scenario is always an important decision. In this paper we analyse behaviour of two different network simulators for a same MANET routing protoc...

The proliferation of everyday smart devices able to sense, process, communicate and/or actuate, is changing the way we interact with the world around us. These novel cyber-physical smart devices, or simply Smart Objects (SOs), are the fundamental building blocks of the Internet of Things (IoT), a global and highly dynamic ecosystem in which heterogeneous typologies of device networks seamlessly...

Establishing and implementation of a whole network in real time scenario is very difficult. It is too much time consuming and costly to deploy a complete test bed component containing multiple networks (computers, routers and data links) to validate and verify a certain network protocol or a specific network algorithm for wired and wireless network. A widespread methodology is used for verifyin...

This paper presents a generalized design for MANET simulations to support any kind of widespread adoption, and standardized to allow universal interoperability, along with flexibility to permit runtime extension of its ontology. Traditional network simulation models often lack these desirable properties. IEEE’s standard 1516 for simulation and modeling fulfill the need for a standard of the kin...
