Click the blue text to follow us with one click “ Dream Thinker NetworkSecurity Guardian ” Security researchers indicate that RFC 7252, also known as the Constrained Application Protocol (CoAP), is about to become one of the most abused protocols in DDoS attacks. What is CoAP? CoAP was officially approved in 2014 and has only … Read more
Introduction The Internet of Things (IoT) refers to the “internet of everything connected,” which is an extension and expansion of the internet, forming a huge network by combining various information sensing devices with the network, enabling connectivity among people, machines, and objects anytime and anywhere. However, many IoT terminals are resource-constrained, with limited storage space … Read more
With the advancement of 5G network technology, the Internet of Things (IoT) is rapidly developing. Today, countless IoT devices are shining in every corner of the world. However, unlike traditional internet, end-to-end communication has always been a challenge for IoT businesses. The different IoT communication protocols used create a huge gap in communication between these … Read more
Labs Guide CoAP, short for Constrained Application Protocol, is a communication protocol based on UDP designed to meet the M2M (Machine-to-Machine) needs in constrained environments. Currently, in the field of IoT protocols, the Matter Protocol 1.0 launched by Google, Amazon, and Apple in collaboration with the CSA Alliance, as well as the OLA Alliance Interoperability … Read more

Recently at Exadel, we encountered an interesting challenge for IoT developers. As IoT applications gain so much momentum, there are more and more options on how to develop them. For device communication, two specialized competing protocols stand out: Message Queue Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP). Both are designed to be lightweight and … Read more
IoT Communication Protocols Communication protocols can be considered a language, allowing two or more devices to communicate with each other. Just like there are rules for any system, communication protocols also follow a set of rules to pass meaningful information between devices. Communication protocols are crucial in distributed systems, where different parts of the same … Read more
Currently, most IoT modules on the market support protocols such as TCP, UDP, CoAP, LwM2M, and MQTT. Among these, there are both transport layer protocols and application layer protocols, with many protocols available for different scenarios. However, when designing a product, usually only one protocol is needed, so how to choose a protocol that fits … Read more
