Apart from allowing users to simulate different DTN scenarios rapidly and in a versatile manner, it also offers an easy way to generate results from the simulations performed. Although the ONE simulator is widely accepted among the DTN research community as a standard DTN simulator, it supports only some limited features of DTN. The current release of the ONE simulator (version 1.6.0) only supports dissemination of messages with textual content over unicast mode of communication. The propagation of messages containing multimedia content and support for multicasting and broadcasting mode of communication are still not included in it. In this paper, we propose to implement the multicast and broadcast modes of communication and dissemination of multimedia content in the ONE simulator. We augment the ONE simulator version 1.5.1 RC-2 to incorporate the proposed features. Two sets of experiments are conducted to validate the implementation of the proposed features. The experimental results demonstrate successful implementation of both the features in ONE simulator.","PeriodicalId":313480,"journal":{"name":"Proceedings of the 10th EAI International Conference on Simulation Tools and Techniques","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125347344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Real-time simulation can also run in parallel for largescale network scenarios, in which case network traffic is represented as simulation events passed as messages to remote simulation instances running on different machines. We note that substantial overhead exists in parallel real-time simulation to support synchronization and communication among distributed instances, which can significantly limit the performance and scalability of the hybrid approach. To overcome these challenges, we propose several techniques for improving the performance of parallel real-time simulation, by eliminating parallel synchronization and reducing communication overhead. Our experiments show that the proposed techniques can indeed improve the overall performance. In a use case, we demonstrate that our hybrid technique can be readily integrated for studies of software-defined networks.","PeriodicalId":313480,"journal":{"name":"Proceedings of the 10th EAI International Conference on Simulation Tools and Techniques","volume":"2010 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114702569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Before the simulation system is running, all the entities are distributed to each logical process. The parallelism of the simulation system depends on the parallelism between logical processes. The performance of this parallel approach is greatly affected by the entity distribution scheme. For example, when the computing hotspots are assigned to one LP, the performance of the parallel simulation is almost the same as that of the serial simulation. And it is difficult to find a suitable entity distribution scheme when it comes to simulation with hotspots which migrate between LPs dynamically. Besides, we always use as many LPs as possible to improve parallelism, but this also brings greater communication and synchronization overhead. Focusing on these drawbacks of current simulation engines, we propose an approach which supports fine grain parallelism in one LP. Based on the traditional time management algorithms, our approach can process events of different entities in one LP in parallel with multi threads.","PeriodicalId":313480,"journal":{"name":"Proceedings of the 10th EAI International Conference on Simulation Tools and Techniques","volume":"48 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132795368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the increase in internationalization in education, the development and implementation of such technologies is now required. However, as yet, the particular challenges and future opportunities associated with the use of such technologies has not been fully investigated. We have conducted interviews with teachers in Ireland and China, to establish their perspectives on the use of of emerging technologies, their current practice, and their future needs and hopes. We found that both teachers had experience with the use of emerging technologies, but only the teacher in China was based in a school which implemented such technologies formally, and this was only in recent years. Novelty was identified as a major reason why students would be expected to embrace emerging technologies in the future. The teacher in China also pointed out potential challenges relating to the availability of high-speed internet in parts of China. We suggest that future research should investigate the perspectives of teachers in Ireland, China, and other countries, on the use of emerging technologies for cross-cultural collaboration, in order to develop a more detailed understanding of the specific needs and challenges such international digital collaboration will bring about.","PeriodicalId":313480,"journal":{"name":"Proceedings of the 10th EAI International Conference on Simulation Tools and Techniques","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125586098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
