In response to the challenges posed by performance scalability and the convergence of multiple ledgers stemming from an expanding network, this study introduces the concept of\n            <jats:italic>Co-Sharding<\/jats:italic>\n            . Within this framework, the ledger maintained by sub-chains overseeing IoT operations in distinct geographic regions is conceptualized as a shard within the Large-scale Internet of Things (LIoT) ledger. Meanwhile, elected nodes within each region assume responsibility for maintaining a coordinating shard, facilitating cross-regional communication and data interaction. Furthermore, our work presents a multi-objective optimization algorithm grounded in the multi-shard paradigm to enact a scheduling strategy that spans various regions. We undertake a series of pertinent experiments and conduct a comparative analysis of scheduling algorithms within the context of a real-world cross-regional agricultural IoT system, utilizing actual operational data. The comparative results demonstrate that, in comparison to intra-sub-region scheduling, the Co-Sharding approach enhances machine utilization rates by approximately 30% and reduces scheduling time by around 18% when confronted with a task count of 12. In terms of performance, Co-Sharding also exhibits the capability to reduce the storage requirements of lightweight nodes within each region by approximately 39% while concurrently improving throughput by approximately 1.5 times when contrasted with a single-chain architecture.\n          <\/jats:p>","DOI":"10.1145\/3641290","type":"journal-article","created":{"date-parts":[[2024,1,19]],"date-time":"2024-01-19T12:11:04Z","timestamp":1705666264000},"page":"1-16","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Co-Sharding: A Sharding Scheme for Large-Scale Internet of Things Application"],"prefix":"10.1145","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-0980-2345","authenticated-orcid":false,"given":"Haotian","family":"Yang","sequence":"first","affiliation":[{"name":"Jiangsu University, Zhenjiang, China and Institute of Food Safety and Nutrition, Jiangsu Academy of Agricultural Sciences, Nanjing , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5698-7938","authenticated-orcid":false,"given":"Xiaoyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Southeast University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2961-4615","authenticated-orcid":false,"given":"Zihan","family":"Wu","sequence":"additional","affiliation":[{"name":"Southeast University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8905-3456","authenticated-orcid":false,"given":"Liangmin","family":"Wang","sequence":"additional","affiliation":[{"name":"Southeast University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3290-507X","authenticated-orcid":false,"given":"Xiao","family":"Chen","sequence":"additional","affiliation":[{"name":"University of Leicester, Leicester, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1013-4507","authenticated-orcid":false,"given":"Lu","family":"Liu","sequence":"additional","affiliation":[{"name":"University of Leicester, Leicester, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2024,3,18]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2019.11.030"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/3448016.3452807"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2020.3020655"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2020.3029221"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1145\/3471140"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","unstructured":"Dan Boneh Joseph Bonneau Benedikt B\u00fcnz and Ben Fisch. 2018.
