Sensor Observation Service (SOS)/Constrained Application Protocol (CoAP) proxy design

2016 18th Mediterranean Electrotechnical Conference (MELECON), 2016
Sensor networks have expanded their scope and capabilities, becoming a fundamental part of the Internet of Things (IoT). To be able to affront the interoperability needs that this rise brings, it is necessary to have a repository with standard interfaces and messages. This has been addressed through the creation of the Sensor Observation Service (SOS).

Energy Saving in Constrained Application Protocol of Internet of Things

International Journal on Communications Antenna and Propagation (IRECAP), 2016
The centralized resource discovery approach in the Constrained Application Protocol (CoAP) is based on the resource directory (RD) model, this directory contains a description for resources held in the servers (sensors and actuators), in which the servers register their resources in the RD while the clients are allowed to perform a lookup operation on ...

A Short Delay Degree-Constrained Hierarchical Application Layer Multicast Protocol

2009 International Conference on Web Information Systems and Mining, 2009
Scalability and efficiency are important for designing application-layer multicast protocol. In this paper, a short delay degree-constrained hierarchical protocol-SDDM is proposed for application-layer multicast. It adopts the idea of layer and cluster to construct multicast group members into a hierarchical architecture.

Deterministische und interoperable Kommunikation mit dem Constrained Application Protocol

2019
In dieser Arbeit wird untersucht, inwieweit sich Echtzeitanforderungen in der Kommunikation mit einer rein Software-basierten Lösung auf Basis etablierter IoT-Standards unter Verwendung von Standardhardware erfüllen lassen. Hierzu wird schrittweise gezeigt, wie sich eine zeitlich deterministische Kommunikation allein auf Basis des Constrained ...

"Too Many Requests" Response Code for the Constrained Application Protocol

2019
A Constrained Application Protocol (CoAP) server can experience temporary overload because one or more clients are sending requests to the server at a higher rate than the server is capable or willing to handle. This document defines a new CoAP Response Code for a server to indicate that a client should reduce the rate of requests.
