Abstract:Recent advances in information and communication technology (ICT) have enabled interaction and cooperation between components of the transportation system, and cooperative eco-driving systems that apply ICT to eco-driving systems are receiving significant attention. A cooperative eco-driving system is a complex system that requires consideration of the electronic control unit (ECU) and vehicle-to-everything (V2X) communication. To evaluate these complex systems, it is needed to integrate simulators with expertise. Therefore, this study presents an integrated driving hardware-in-the-loop (IDHIL) simulator for the testing and evaluation of cooperative eco-driving systems. The IDHIL simulator is implemented by integrating the driving hardware-in-the-loop simulator and a vehicular ad hoc network simulator to develop and evaluate a hybrid control unit and cooperative eco-driving application for the connected hybrid electric vehicle (CHEV). A cooperative eco-driving speed guidance application is utilized to demonstrate the use of our simulator. The results of the evaluation show the improved fuel efficiency of the CHEV through a calculation of the optimal speed profile and the optimal distribution of power based on V2X communication. Finally, this paper concludes with a description of future directions for the testing and evaluation of cooperative eco-driving systems.Keywords: hardware-in-the-loop (HIL); VANET simulator; driving simulator; cooperative eco-driving; integrated simulator; connected hybrid electric vehicle

Castalia: Castalia ,  is a simulator for WSNs (WSN), body area networks (BAN) and generally networks of low-power embedded devices that is based on OMNeT++. It is developed at the National ICT Australia since 2006 and made public as open source under the Academic Public License in 2007.
SENS ,  is an application-oriented simulator for WSNs. It has a modular, layered architecture so that components for applications, network communication and the physical environment can be easily interchanged and extended. Due to different component implementations, which varies in the degree of realism, application-specific environments can be created and simulated. Due to the chosen approach, SENS enables application portability because the same source code can be run with in a simulation or deployed on actual sensor nodes.
SENSE (Sensor Network Simulator and Emulator) ,  is a simulator for WSNs that is based on a novel component-oriented simulation methodology, which promotes extensibility and reusability. At the same time, the simulation efficiency and the scalability was considered. In the component repository of SENSE there are already different components available from the application to the physical layer including IEEE 802.11, AODV, DSR, SSR, SHR as well as Battery Models and a Power Model. At the moment, there does not seem to be any further tools included in SENSE so that, for example, a visualization tool to analyze the network behavior graphically is missing.
Simulation tools are essential for validating any research idea before it is being implemented. This is very essential for all the researchers irrespective of the field of research. Simulators provide a way for analysing the design. There are many simulation tools available for the network researchers. Network Simulators are used to test the performance of existing or new algorithms and protocols.Some of the simulation tools in networking include OPNET (optimized Network Engineering Tool), NS-2 (Network Simulator version 2), OMNET++ (Objective Modular NETwork Testbed in C++), GloMoSim (Global Mobile Information System Simulator), QualNet, NetSim (Network Simulator), JiST/SWANS (Java in Simulation Time/ Scalable Wireless Network Simulator), J-Sim (Java-based simulation) and NS-3 (Network Simulator Version 3). Simulation tools may be open source or commercial. In this paper, both the open source and commercial simulators are discussed. This survey reveals that for simulating large networks, simulators like OPNET, GloMoSim, QualNet, NetSim, JiST/SWANs and NS-3 can be used. For small network simulation NS-2 and J-Sim can be preferred. Open source simulators are poor in documentation. Commercial simulators have good documentation. Based on the requirements of the research, a proper simulation tool can be selected.
Simulators play an important role in research. Network Simulators are used to design and evaluate the network algorithms and routing protocols under varying network conditions (Breslauet al., 2000). Mobile Ad hoc-Network (MANET) is a collection of mobile nodes forming temporary network without any predefined infrastructure. These networks are used in emergency situations such as in battlefields and emergency medical rescue. For routing in Mobile Ad hoc Networks, routing protocol must be deployed. Before implementing the routing protocol its behaviour must be analysed by simulation. So network simulators are used for simulating these routing protocols or other algorithms in wired and wireless networks.
The organization of the rest of the paper is as follows: Next section discuss about the related work in simulator survey. Section 3 deals with different network simulation tools that are available for network research. It also describes the merits and demerits of the simulators. Section 4 presents the comparison of about nine network simulators based on the parameters like license, operating system and language used, year of release, user interface, protocol and mobility support, scalability, extendibility, documentation, network and emulation support etc. Last section concludes with the consolidation of merits and demerits of the simulators and suggests the design of new simulator that satisfies all the requirements of the researcher as future enhancement.
Many researchers have presented the survey on various network simulation tools. Malhotra (2014) explained the MANET Simulators such as NS-2, NS-3, OMNET++, OPNET, GloMoSim, QualNet and SWANS in their work. Some features of these simulators such as the languages involved and the network supported by them were discussed and their limitations were presented. In addition to this, the issues related to documentation, installation were also discussed. But this survey does not deal with the protocols and the mobility models supported by the simulator. Gupta, Ghonge, Thakare, and Jawandhiya (2013) discussed the open source network simulators such as NS-2, NS-3, OMNET++ and J-Sim. The main features of the open source simulators were presented along with their advantages and disadvantages. The architecture of the four simulators was also explained. This survey may not be considered as a complete survey of network simulation tools because they have considered only the open source simulators. Commercial simulators were not taken into account by the authors. They suggested NS-2 as thebest simulator, for GUI interested research OMNET++ can be preferred for simulating large networks, NS-3, OMNET++ and J-Sim were better than NS-2. Jambii, Leñando, Zen, Suhaili, and Tully (2012) made the survey of existing simulation tools for Mobile Adhoc Sensor Networks. Nearly fifteen simulation tools were discussed and a comparative study of selected simulators were made based on certain evaluation metrics like energy model, mobility model, license, bridging of code, scalability, protocol support, technical support and GUI support. Many features of the simulator were presented but it lacks in the types of protocols supported by the simulator in different layers and the mobility models. In this survey, the details of the individual feature of the simulators were not clearly mentioned. According to the authors, integration of different simulators may be useful for getting better results. Mallapur, (2012) described four network simulators such as NS-2,OMNET++, NCTUns (National Chiao Tung University network simulator) and GloMoSim. They discussed the features, advantages and disadvantages of the above mentioned four simulators. Then comparison of these simulators was done based on certain mainstreams like emulation support, license, GUI, interface, available modules, documentation and user support, scalability, extendable and simulation technique. Several network simulators are available but only four simulators were described by the authors in this survey. They conclude that NS-2 and OMNET++ were the best simulators for ad hoc network because NS-2 supports wide range of protocols in all layers and OMNET++ provides powerful GUI. They added that GloMoSim can be used for large network simulation. In the survey on telecommunication network simulators (Sarkar & Halim, 2011), a comparison of network simulators was done based on the type, deployment mode, network impairments and protocol support. Only limited features of simulators were highlighted in this survey. In their survey they found that most of the papers published in IEEE conference and proceedings use NS-2 for network modelling and simulation task. Three specific recommendations were provided by the authors for the network researchers such as to choose a credible simulator, to build credible simulation models and to use statistical methods to improve the credibility of results. 2b1af7f3a8
