“…The ESYS (External System) API [20] embedded in Opnet provides a method for external code (known as cosim) to pass values (this may include packets, structures, floats) to and from Opnet simulations via defined interfaces. This can be used to pass information from an external simulation like Matlab/Simulink into an Opnet network simulation.…”

“…When the velocity rises to Normal (50, 1), the MR begins to fluctuate and approximately 50% transactions have been missed. The performance at Normal (60, 1) is unsatisfied (20,1). In summary, our TS-WRR could well organize vehicles' access in usual highway scenarios but also issue worse performance when topology changing is drastic and mobility level is too high.…”

In Vehicular communication networks, a robust access mechanism is essential for the successful information exchange between vehicles and roadside unit, which keeps the vehicles being aware of surroundings thus improving driving safety and reduce traffic jam. In this paper, we first analyze the drawbacks of explicit GTS (Guaranteed Time Slots) allocation suggested by IEEE 802.15.4 draft and show the importance of a wise assignment scheme and efficient scheduler especially for high dynamic vehicular environment. Then, for a given number of vehicles requesting to access the roadside unit, we propose a Time-Sensitive Weighted Round Robin scheduler (TS-WRR) considering different service delay requirements, packets arrival rates and vehicles' mobility levels. We also show the elaborate implementation procedure of TS-WRR by pseudocode. Numerical results show that our TS-WRR scheduler outperforms FCFS and WRR on the performance of transactions delay requirements guarantee and GTS utilization ratio in Vehicular Sensor Networks.

“…For example, by using the external system API in OPNET, Harding designed an interface between MATLAB and OPNET, for constructing a simulation of an NCS based on MANETs (Mobile Ad Hoc Networks) [20]. The interface can be used to pass dynamic system information, from an external simulation performed in MATLAB/Simulink, into an OPNET network simulation.…”

“…It integrates the Open Dynamics Engine, a library used to simulate robot physics, into OMNeT++, a network simulation tool. Another example is a simulation environment for distributed wireless NCSs operating over a MANET based on OPNET [20]. However, it is difficult for these systems to simulate co-design methodologies, which involve close relationships between network and control system behaviours.…”

Abstract-Discrete event-driven simulations of digital communication networks have been used widely. However, it is difficult to use a network simulator to simulate a hybrid system in which some objects are not discrete event-driven but are continuous time-driven. A networked control system (NCS) is such an application, in which physical process dynamics are continuous by nature. We have designed and implemented a hybrid simulation environment which effectively integrates models of continuous-time plant processes and discrete-event communication networks by extending the open source network simulator NS-2. To do this a synchronisation mechanism was developed to connect a continuous plant simulation with a discrete network simulation. Furthermore, for evaluating codesign approaches in an NCS environment, a piggybacking method was adopted to allow the control period to be adjusted during simulations. The effectiveness of the technique is demonstrated through case studies which simulate a networked control scenario in which the communication and control system properties are defined explicitly.

In this paper we present a way to use adaptive antenna arrays in OPNET (Optimized Network Evaluation Tool) simulations. Adaptive antenna patterns, which are not supported by OPNET directly, can be implemented by interfacing OP-NET with MATLAB, which performs the necessary calculations in beamforming. A MAC (Medium Access Control) protocol which is designed from the start to take advantage of an adaptive antenna system is used to demonstrate the setup.
