Kamble, S.Chandavarkar, B.R.2026-02-0620212021 12th International Conference on Computing Communication and Networking Technologies, ICCCNT 2021, 2021, Vol., , p. -https://doi.org/10.1109/ICCCNT51525.2021.9579694https://idr.nitk.ac.in/handle/123456789/30221The network types are getting updated from wired to wireless and wireless to Low Power and Lossy Networks (LLNs) based on the applications. Hence there is a need for a routing protocol that supports the latest properties of the network. The paper reviews the criteria defined by ROLL for LLNs. The paper also provides a discussion on how some of the protocols behave in context to these criteria. The paper also mentions the requirement of various categories of loT applications. A protocol that satisfies the criteria is considered to be suitable for LLNs with some necessary features. A protocol should also satisfy the requirements of a wide range of applications so that the protocol designed is reliably used. © 2021 IEEE.Internet of ThingsLow power and lossy network (RPL)RoutingRouting CriteriaRouting protocolWired NetworkWireless Networks
