Item Expectation-Based Multi-Attribute Multi-Hop Routing (EM2R) in Underwater Acoustic Sensor Networks(Institute of Electrical and Electronics Engineers Inc., 2020) Chandavarkar, B.R.; Gadagkar, A.V.Underwater acoustic sensor networks (UASNs) have been a recommended technology for acquiring details from underwater. These networks has underwater sensors that have energy constraints and use acoustic communication medium. Routing in UASN is one of the primary issues, as the data need to be forwarded utilizing minimum energy and higher packet delivery rate. Deciding the next forwarding node play a significant role in routing algorithms for UASN and directly impact packet delivery and energy consumed by the nodes. This paper proposes an expectation-based multi-attribute multi-hop routing (EM2 R) in underwater acoustic sensor networks. EM2 R uses node's residual energy and distance as a multi-attribute criterion in selecting next-hop for routing. Further, the detailed implementation of EM2 R in industry-standard underwater network simulator referred to as UnetStack is presented. Additionally, the performance of EM2 R is presented with reference to the selection of the forwarding node and their energy depletion, delay, and throughput. © 2020 IEEE.Item Routing Criteria for Low Power and Lossy Networks(Institute of Electrical and Electronics Engineers Inc., 2021) Kamble, S.; Chandavarkar, B.R.The 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.
