BDP-CoAP: Leveraging Bandwidth-Delay Product for Congestion Control in CoAP
2019 IEEE 5th World Forum on Internet of Things (WF-IoT), 2019CoAP is one of the most popular protocols for data transfer in IoT networks. Since COAP uses an unreliable transport protocol (UDP) to deliver application data, loss-based congestion control algorithms are introduced in CoAP to mitigate network congestion.

2016 International Conference on Information Networking (ICOIN), 2016
IoT has emerged to realize the notion of ubiquitous interaction of everything. With the help of IoT, various types of objects including human, machine, and almost all things can communicate with each other via the Internet. However, the current state of the art in IoT technology focuses on the limited application such as signalling and exchange of ...

Observing CoAP groups efficiently
Ad Hoc Networks, 2016It is envisioned that by the year 2020 the Internet will contain more than 50 billion devices, among which the majority of them will have constraints in terms of memory, processing power or energy. As a consequence, they are often unable to run current standard Internet protocols, requiring special, optimized protocols.

Proceedings of the Seventh International Conference on the Internet of Things, 2017
Smart Grids are one of the main consequences of the digitalization of electrical grid infrastructures that aim to improve energy saving and efficiency. Within Smart Grids, different devices and electrical substations communicate with each other and need to be accessible from the outside.

REST-ful CoAP Message Authentication
2015 International Workshop on Secure Internet of Things (SIoT), 2015One core technology for implementing and integrating the architectural principles of REST into the Internet of Things (IoT) is CoAP, a REST-ful application protocol for constrained networks and devices. Since CoAP defaults to UDP as transport protocol, the protection of CoAP-based systems is realised by the adoption of DTLS, a transport-oriented ...

NodeMCU Choreography Automation by CoAP
2019 International Conference on Information Networking (ICOIN), 2019The internet of things (IoT) plays an important role in our lives and this role is significantly increasing. The combination operation of a device or a NodeMCU is used to reduce cost, gather information, and command and control devices. The most beneficial use of the IoT is to help smart farms, home automation, smart factories, smart cities and big ...

IoT Protocols – MQTT versus CoAP
Proceedings of the 4th International Conference on Networking, Information Systems & Security, 2021The usage of Internet of Things has increased in the recent years allowing a new way of connecting devices together. Many transactions happen over the IoT calling for protocols to ensure the efficiency and management of the communication traffic. This paper examines 2 particular protocols, Message Queuing Telemetry Transport (MQTT) and Constrained ...

Analysis of QUIC Transported CoAP
SN Computer Science, 2021Many IoT deployments rely on an access network that is characterized by densely distributed power constrained devices. Power restrictions, in turns, lead to transmission rate limitations and increased bit errors responsible of network packet loss. Among the many technologies available to deal with these issues, the Constrained Application Protocol ...

6LoWPAN Compressed DTLS for CoAP
2012 IEEE 8th International Conference on Distributed Computing in Sensor Systems, 2012Real deployments of the IoT require security. CoAP is being standardized as an application layer protocol for the Internet of Things (IoT). CoAP proposes to use DTLS to provide end-to-end security to protect the IoT. DTLS is a heavyweight protocol and its headers are too long to fit in a single IEEE802.15.4 MTU.
