Internet - Draft Conditional observe in CoAP March 2012
نویسنده
چکیده
CoAP is a RESTful application protocol for constrained nodes and networks. Through the Observe option, clients can observe changes in the state of resources. This document defines a new mechanism in CoAP Observe so that a CoAP client can conditionally observe a resource on a CoAP server, only being informed about state changes meeting a specific condition.

Internet - Draft Conditional observe in CoAP
CoAP is a RESTful application protocol for constrained nodes and networks. Through the Observe option, clients can observe changes in the state of resources and obtain a current representation of the last resource state. This document defines a new mechanism in CoAP Observe so that a CoAP client can conditionally observe a resource on a CoAP server, only being informed about state changes meeti...
متن کاملEnsuring Interoperability for the Internet of Things: Experience with CoAP Protocol Testing
Constrained Application Protocol (CoAP) is a specialized web transfer protocol, designed for realizing interoperation with constrained networks and nodes for machine to machine applications like smart energy, building automation, etc. As an important ubiquitous application protocol for the future Internet of Things, CoAP will be potentially implemented by a wide range of smart devices to achiev...
متن کاملCoap Utilization for Building Control Draft-vanderstok-core-bc-05
This draft describes an example use of the RESTful CoAP protocol for building automation and control (BAC) applications such as HVAC and lighting. A few basic design assumptions are stated first, then URI structure is utilized to define group as well as unicast scope for RESTful operations. This proposal supports the view that 1) service discovery is complementary to resource discovery and faci...
متن کاملCoCoA+: An advanced congestion control mechanism for CoAP
The Constrained Application Protocol (CoAP) has been designed by the Internet Engineering Task Force (IETF) for Internet of Things (IoT) devices. Due to the limited radio channel capacities and hardware resources of such devices, congestion can be a serious problem. CoAP addresses this important issue with a basic congestion control mechanism. CoCoA, an Internet-Draft proposal, introduced alter...
متن کاملCoAP (Constrained Application Protocol) implementation in M2M Environmental Monitoring System
In order to enable M2M devices to communicate over the existing Internet, Constrained RESTful Environments (CoRE) working group at the Internet Engineering Task Force (IETF) proposed Constrained Application Protocol (CoAP) as application layer protocol for IP based solutions. This paper presents a survey of the CoAP (Constrained Application Protocol), along with its implementation and evaluatio...
