Evaluation of CoAP Implementations for Live Streaming using CoAP-Observe
2019 IEEE 5th World Forum on Internet of Things (WF-IoT), 2019CoAP (Constrained Application Protocol) enables embedded devices to offer RESTful Web Services and exchange small binary message headers. Next to the transmission of sensor data and control information between smart home devices, there is an application field of streaming data using CoAP.

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 ...

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 ...

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.

A CoAP-gateway for smart homes
2012 International Conference on Computing, Networking and Communications (ICNC), 2012The ”Internet of Things” has led to a number of standardization efforts that can make proprietary protocols for home automation obsolete. One of the latest developments is the Constrained Application Protocol (CoAP) that is intended to be used as the HTTP-replacement for smart objects that are connected to the Internet.

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 ...

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.

Enabling CoAP into the swarm: A transparent interception CoAP-HTTP proxy for the Internet of Things
2017 Global Internet of Things Summit (GIoTS), 2017A major challenge in interconnecting billions of computing devices in the Internet of Things (IoT) is interoperability. One approach that is gaining momentum is the Web of Things, that uses web architecture and web standards as a framework for creating IoT applications. Two main protocols are used in the application layer of the Web of Things: HTTP and

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-
