Applications of CoAP

What is CoAP?

CoAP or Constrained Application Protocol, as the name suggests, is an application layer protocol that was introduced by the Internet Engineering Task Force in the year 2014. CoAP is basically designed for the constrained environment....

Methods in CoAP

CoAP is a web-based protocol. This means CoAP resembles the HTTP protocol and is capable to utilize the HTTP methods.These methods are-...

Message Format of CoAP

CoAP messages are encoded in binary-format or 0/1 format. Like other message formats, CoAP message has a header and a payload section along with an optional section....

Applications of CoAP

Real Time Monitoring in Grid – Smart cities can monitor the distribution and generation of power remotely. The CoAP sensors could be embedded inside the transformers and the data could be transferred over GPRS or 6LowPAN. Defense utilities – The armory and tanks are now-a-days fitted with sensors so that information could be communicated remotely without any interference. The CoAP sensors could detect any intrusion. This makes them capable to transfer more data even under low bandwidth network. Aircraft utilities – The Aircraft sensors and actuators could be connected with other sensors and communication can take place using smart CoAP based sensors and actuators....

Conclusion

A lot of modern world tasks could be eased out with the help of CoAP protocols. Due to less overhead and capability to transfer data effectively even under low bandwidth, CoAP has became a primarily choice for IoT and cloud computing system architecture. CoAP messages have a fixed size header which is of 4 bytes. Alongside this, CoAP message format have some optional fields which includes fields like token, options, and payload. This message format of CoAP is binary encoded in 0/1 format. CoAP works on request response model which majorly resembles HTTP methods like GET, POST, PUT, and DELETE along with its own unique method Observe...
