Adoption of Constrained Application Protocol

International Journal of Innovation in the Digital Economy, 2016
Among billions of Internet enabled devices that are expected to surround us in the near future, many will be resource constrained, i.e., will have limited power supply, processing power and memory. To cope with these limitations, the Constrained Application Protocol (CoAP) has been recently introduced as a lightweight alternative to HTTP for connecting

An optimization‐based congestion control for constrained application protocol

International Journal of Network Management, 2021
SummaryThe Constrained Application Protocol (CoAP) is a lightweight web transfer protocol designed based on the REST architecture standardized by the Internet Engineering Task Force (IETF) to meet and accommodate the requirements of the constrained Internet of Things (IoT) environments.

Constrained Application Protocol (CoAP) Hop-Limit Option

2020
The presence of Constrained Application Protocol (CoAP) proxies may lead to infinite forwarding loops, which is undesirable. To prevent and detect such loops, this document specifies the Hop-Limit CoAP option.

Evaluation of constrained application protocol for wireless sensor networks

2011 18th IEEE Workshop on Local & Metropolitan Area Networks (LANMAN), 2011
IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) and IPv6 Routing Protocol for Low-power and Lossy networks (RPL) have accelerated the integration of Wireless Sensor Networks (WSNs) and smart objects with the Internet. At the same time, the development of the Constrained Application Protocol (CoAP) has made it possible to provide resource ...

Performance study of the constrained application protocol in lossy networks

2019 IFIP Networking Conference (IFIP Networking), 2019
The Constrained Application Protocol (CoAP) is a lightweight core protocol used for communication between devices in the Internet-of-Things. The CoAP standard defines a simple congestion control mechanism based mainly on retransmissions after timeouts and a binary exponential back-off procedure with randomization.

Multipart Content-Format for the Constrained Application Protocol (CoAP)

2020
This memo defines application/multipart-core, an application- independent media-type that can be used to combine representations of zero or more different media types into a single message, such as a CoAP request or response body, with minimal framing overhead, each along with a CoAP Content-Format identifier.

CoAP (Constrained Application Protocol) over TCP, TLS, and WebSockets

2018
The Constrained Application Protocol (CoAP), although inspired by HTTP, was designed to use UDP instead of TCP. The message layer of CoAP over UDP includes support for reliable delivery, simple congestion control, and flow control. Some environments benefit from the availability of CoAP carried over reliable transports such as TCP or Transport Layer ...

The Constrained Application Protocol for pervasive machine-to-machine communications

2012 IEEE International Conference on Pervasive Computing and Communications Workshops, 2012
In the Constrained RESTful Environments (CoRE) working group at the Internet Engineering Task Force (IETF) a Representational State Transfer (REST) architecture is being defined for constrained nodes and networks, e.g. Wireless Sensor Networks (WSN). The CoRE working group has already proposed a standard called Constrained Application Protocol (CoAP ...

Constrained Application Protocol for Low Power Embedded Networks: A Survey

2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing, 2012
IPv6 will make it possible to provide Internet connectivity to any object embedding a communication device. In the same line, Web technologies will make managing, communicating and visualizing any information provided by these devices attractive to the end users and application developers.
