For example, in industrial sites with large metal constructions (such as petrochemical plants), highly localized and time-varying changes in wireless link quality are quite common. Oddly enough, much of the capabilities needed to deal with such effects are already present at the physical layer (PHY), but remain largely unexploited by higher protocol layers. In fact, little Industrial Internet of Things (IoT) (IIoT) research has considered harnessing the full multi-modal capabilities of modern multi-PHY\/multi-band IoT hardware in general. As such, in this vision paper, we: (1) analyze recent advances towards enabling multi-modal IIoT through link- and routing layer operations; and (2) describe challenges and opportunities for future IIoT deployments, based on the design choices that emerged from said analysis. In summary, we identify a combination of a modified\/extended Time-Slotted Channel Hopping (TSCH) link layer, using either fixed or variable duration timeslots, together with a Parent-Oriented (PO) Routing Protocol for Low-Power and Lossy Networks (LLNs) (RPL) approach to be the most promising way forward.<\/jats:p>","DOI":"10.1007\/s11277-023-10213-w","type":"journal-article","created":{"date-parts":[[2023,3,22]],"date-time":"2023-03-22T18:02:28Z","timestamp":1679508148000},"page":"1-24","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Multi-Modal Industrial IoT Networks: Recent Advances and Future Challenges"],"prefix":"10.1007","volume":"140","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4427-6987","authenticated-orcid":false,"given":"Robbe","family":"Elsas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dries","family":"Van Leemput","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeroen","family":"Hoebeke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eli","family":"De Poorter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,3,22]]},"reference":[{"key":"10213_CR1","unstructured":"IEEE Standard for Low-Rate Wireless Networks, IEEE Std 802.15.4-2020 (Revision of IEEE Std 802.15.4-2015), July (2020)."},{"key":"10213_CR2","doi-asserted-by":"crossref","unstructured":"Chen, Y., Lu, S., Kim, H.-S., Blaauw, D., Dreslinski, R.
