{"title":"Performance evaluation of TSCH-minimal and orchestra scheduling in IEEE 802.15.4e networks","authors":"Mohamed Mohamadi, Badis Djamaa, Mustapha Réda Senouci","doi":"10.1109/ISPS.2018.8379007","DOIUrl":"https://doi.org/10.1109/ISPS.2018.8379007","url":null,"abstract":"Having been considered as a key enabler for the Internet of Things (IoT), the IEEE 802.15.4 standard is, now, emerging as a main pillar of the evolving Industrial IoT (IIoT), thanks to its Time Slotted Channel Hopping (TSCH) mode. TSCH allows nodes, in an IIoT network, to hop between the 16 channels of the IEEE 802.15.4 standard within specified timeslots in order to meet the reliability and real-time requirements of industrial applications, while saving nodes energy. A TSCH schedule dictates to each node what to do in each timeslot, that is: send, receive or sleep. However, the IEEE 802.15.4-TSCH specification does not provide mechanisms on how to build or maintain such a schedule. To address this issue, many solutions have been recently proposed, including a standard minimal schedule (TSCH-Minimal) by the Internet Engineering Task Force and a promising advanced solution dubbed Orchestra. This paper presents a comprehensive study and a performance evaluation of these state-of-the-art solutions in order to extract their advantages and drawbacks. Obtained results from extensive realistic simulations conducted in dedicated IIoT platforms, show that, overall, Orchestra outperforms TSCH-Minimal in reliability and energy aspects. On the latency and complexity aspects, however, TSCH-Minimal has shown noticeable performance. Based on such results, this study concludes the need for a hybrid TSCH scheduling mechanism that benefits from both worlds.","PeriodicalId":294761,"journal":{"name":"2018 International Symposium on Programming and Systems (ISPS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133723094","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}

Ultimately, everything that we see and don't see will be connected to the Internet. These Web-enabled “things” will be continuously streaming data whose size and volume will dwarf anything we have witnessed so far. This is called Big data. It is here to stay and in a big way. It is coming from all sorts of sensors, including instruments conducting deep space exploration from earth or satellites, highly sensorized high-energy physics, social media, smartphones, genomics machines, etc. The cloud has been instrumental in supporting the storage and processing of the ever increasing amount of data. “Domesticating” IoT data, i.e., making it useful, however, has been a major challenge. Service computing is the next major evolution of computing that aims at transforming massive data into artefacts that are acted upon and made “useful”, i.e., turned into services. In this talk, I will first overview the big data trend produced by human and physical sensors. I will then motivate the need for a uniform service management to service IoT data. I will then describe our latest research that focuses on servicing IoT-based sensor clouds.","PeriodicalId":294761,"journal":{"name":"2018 International Symposium on Programming and Systems (ISPS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126382774","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}

Numerical results on a set of benchmarks showed the efficiency of the developed model to find better results compared with some other literature works.","PeriodicalId":294761,"journal":{"name":"2018 International Symposium on Programming and Systems (ISPS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128563426","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}
