6LoWPAN Compressed DTLS for CoAP

2012 IEEE 8th International Conference on Distributed Computing in Sensor Systems, 2012
Real 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), 2012
The ”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), 2019
The 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), 2017
We 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), 2017
A 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, 2014
The 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-

Managing 6LoWPAN sensors with CoAP on internet

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
In 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.

Computing the Retransmission Timeout in CoAP

2013
The most prominent IT trend nowadays is connection of Wireless Sensor Networks (WSNs) with Internet service infrastructure. Interconnection of the millions of sensor and processing devices will create a tremendous traffic increase that can lead to congestion.

CoAP-CTX: A Context-Aware CoAP Extension for Smart Objects Discovery in Internet of Things

2017 IEEE 41st Annual Computer Software and Applications Conference (COMPSAC), 2017
In the Internet of Things paradigm, the total number of interconnected smart objects tends to increase in elevate rates in the next years, creating an overload of objects to be controlled and configured by the users themselves. Alternatively, context-aware discovery services have potential to minimize this problem by applying rules to determine which ...

$$\lambda $$ -CoAP: An Internet of Things and Cloud Computing Integration Based on the Lambda Architecture and CoAP

2016
The Internet of Things (IoT) is an emerging technology that is growing continuously thanks to the number of devices deployed and data generated. Nevertheless, an upper layer to abstract the limitations of storing, processing, battery and networking is becoming a mandatory need in this field. Cloud Computing is an especially suitable technology that can
