Nonetheless, the standard only provides a framework, but it does not mandate a specific scheduling mechanism for time and frequency slot allocation. This paper focuses on a centralized scheme to schedule multiple concurrent periodic real-time flows in TSCH networks with mesh topology. In our scheme, each flow is assigned a dynamic priority based on its deadline and the hops remaining to reach the destination. A maximum matching algorithm is utilized to find conflict-free links, which provides more chances to transfer high-priority flows at each time slot. Frequency allocation is implemented by graph coloring to make finally selected links interference free. Simulation results show that our algorithm clearly outperforms the existing algorithms on the deadline satisfaction ratio with a similar radio duty cycle.<\/jats:p>","DOI":"10.1155\/2019\/4639789","type":"journal-article","created":{"date-parts":[[2019,9,22]],"date-time":"2019-09-22T19:30:58Z","timestamp":1569180658000},"page":"1-12","source":"Crossref","is-referenced-by-count":7,"title":["Transmission Scheduling of Periodic Real-Time Traffic in IEEE 802.15.4e TSCH-Based Industrial Mesh Networks"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4250-6208","authenticated-orcid":true,"given":"Ke","family":"Shi","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}]},{"given":"Lin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}]},{"given":"Zhiying","family":"Qi","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}]},{"given":"Kang","family":"Tong","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}]},{"given":"Hongsheng","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, Hubei University of Science and Technology, Xianning 437005, China"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/tc.2014.2322609"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/5349894"},{"key":"4","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.comcom.2016.05.004","volume":"88","year":"2016","journal-title":"Computer Communications"},{"key":"5","first-page":"111","volume-title":"6TiSCH wireless industrial networks: determinism meets IPv6","volume":"vol. 9","year":"2014"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2017.10.004"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2017.05.014"},{"key":"10","first-page":"3","volume-title":"Adaptive k-cast scheduling for high-reliability and low-latency in IEEE802.15.4-TSCH","volume":"11104","year":"2018"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/jsen.2015.2480886"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/jsen.2013.2266417"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2014.6710073"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1177\/1550147717713629"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.2298\/csis150401005g"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1177\/1550147717726311"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1007\/s11036-017-0887-9"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.4153\/cjm-1965-045-4"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1002\/ett.3494"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/4639789.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/4639789.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/4639789.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,22]],"date-time":"2019-09-22T19:31:01Z","timestamp":1569180661000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2019\/4639789\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9,22]]},"references-count":16,"alternative-id":["4639789","4639789"],"URL":"https:\/\/doi.org\/10.1155\/2019\/4639789","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"type":"print","value":"1530-8669"},{"type":"electronic","value":"1530-8677"}],"subject":[],"published":{"date-parts":[[2019,9,22]]}}}
