    Data formats and its research challenges in iot: A survey
    (Springer Science and Business Media Deutschland GmbH, 2021) Mahanthappa, S.; Chandavarkar, B.R.
    In the current context, the increase in data generated by the heterogeneous IoT sensors results in several challenges to the IoT applications’ developers. One of the significant problems is handling nonstandardized zeta bytes of heterogeneous IoT data. Further, there is a lack of understanding of data generated by the sensors and incompatibility in representing the data. The objective of this survey paper is to introduce IoT sensors with their areas of applications, the different data formats, representing the data in an interchangeable format, and handling data as a stream. Further, this paper also presents challenges and research opening in IoT data. © Springer Nature Singapore Pte Ltd 2021.

    Void-aware routing protocols for underwater communication networks: A survey
    (Springer Science and Business Media Deutschland GmbH, 2021) Nazareth, P.; Chandavarkar, B.R.
    Underwater Acoustic Sensor Networks (UASNs) is a technology used in several marine applications like environment prediction, defense applications, and discovering mineral resources. UASNs has several challenges like high bit error rate, high latency, low bandwidth, and void-node problem during routing. In the context of routing protocols for underwater communication networks, the void-node problem is one of the major challenging issues. The void-node problem arises in the underwater communication during the greedy-forwarding technique, due to which packet will not be forwarded further toward the sink. In this review paper, we analyze the void-node problem in underwater networks and issues related to the void-node. Also, we elaborate on the significant classification of void-handling routing protocols. We analyze both location-based and pressure-based void-handling routing protocols. © Springer Nature Singapore Pte Ltd 2021.

    Mitigation of RPL stateless address auto-configuration IPV6 spoofing attack in IOT
    (Apple Academic Press, 2023) Yadav, S.; Gangwar, S.; Kembhavi, P.; Chandavarkar, B.R.; Kamble, S.
    As wireless network usage is expanding, attempts are being made to disrupt the smooth functioning of the network. Due to power and memory constraints inherent in the Internet of Things (IoT) devices, implementing security measures becomes an even more significant challenge. There are many ways in which confidential information can be extracted from networks. IP address spoofing is one such attack. IP address spoofing is an illegal, unauthorized change of IP address. Malicious elements in the network impersonate as a genuine client by copying their IP address. As a result, attackers can intercept network communication between genuine clients. A false IP address makes it possible for the attacker to bypass existing security mechanisms, which creates severe security and confidentiality problems. This chapter proposes a method to resolve the issue by ensuring that an incoming node in a network always gets a unique IP address, thus making it difficult for the attacker to disguise itself as a genuine client and carry out the attack. © 2023 Apple Academic Press, Inc.
