IoT Protocols – MQTT versus CoAP
International Conferences 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.

CoAP Proxy Virtualization for the Web of Things
2014 IEEE 6th International Conference on Cloud Computing Technology and Science, 2014The future Web of Things (WoT) foresees a web in which applications can seamlessly access physical objects through the same REST interface used today to access web services. A key enabler of this shift is the Constrained Application Protocol (CoAP), a redesign of the popular HTTP protocol that aims at supporting resource-constrained devices for Machine-

‘COAPE-ing’ with pet behaviour problems
Veterinary Nursing Journal, 1995Dear COAPE,—One of our clients is desperate to enjoy cuddling her cat, Pinta, and to have him curl up asleep on her knee, but he seems afraid of her. She is confined to a wheelchair and I can understand that this could frighten him, but even when she sits very still and tries to call him, he either runs away or will only come and rub around her feet ...

Managing 6LoWPAN sensors with CoAP on internet
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015In this paper, we focus on accessing issue to IPv6 over Low Power Wireless Personal Area Networks (6LoWPAN) sensors. Constrained Application Protocol (CoAP) standard defined by IETF and standardisation works are still going on, is used to access and control 6LoWPAN sensors on internet.

CoAP for content-centric networks
2017 14th IEEE Annual Consumer Communications & Networking Conference (CCNC), 2017We analyze the design space for implementing the Constrained Application Protocol (CoAP) within Content-Centric Networks (CCN), identifying several CoAP specific scenarios and seeing how they map to CCNs. We present an evaluation, recommendations for implementations and extensions, and directions for future work.

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.

Time Synchronization for CoAP using NS2 [PDF]
2019 5th International Conference On Computing, Communication, Control And Automation (ICCUBEA), 2019 Wireless Sensor Networks (WSNs) is made up of a network of many compact and constrained sensors. Constrained Application Protocol (CoAP) was designed particularly for the constrained nodes and networks in WSNs as a unique web transfer protocol by the Internet engineering task force (IETF) developed.

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 ...
