A Low-Power CoAP for Contiki [PDF]
Internet of Things devices will by and large be battery-operated, but existing application protocols have typically not been designed with power-efficiency in mind. In low-power wireless systems, power-efficiency is determined by the ability to maintain a low radio duty cycle: keeping the radio off as much as possible.

IoT Security: Threats and Possible Solutions [PDF]
Despite IoT being in the spotlight for several years now, Gartner still predicts a five time increase in number of devices from 2018 to 2028 [1], up to 1.9 billion units, which further intensifies the need for security among IoT nodes. Through the years,

A Performance Analysis of Internet of Things Networking Protocols: Evaluating MQTT, CoAP, OPC UA
IoT data exchange is supported today by different communication protocols and different protocolar frameworks, each of which with its own advantages and disadvantages, and often co-existing in a way that is mandated by vendor policies. Although different

A Sleep-Awake Scheme Based on CoAP for Energy-Efficiency in Internet of Things
Internet Engineering Task Force (IETF) have developed Constrained Application Protocol (CoAP) to enable communication between sensor or actuator nodes in constrained environments, such as small amount of memory, and low power. IETF CoAP and HTTP are used

CoAP congestion control for the internet of things [PDF]
CoAP is a lightweight RESTful application layer protocol devised for the IoT. Operating on top of UDP, CoAP must handle congestion control by itself. The core CoAP specification defines a basic congestion control mechanism, but it is not capable of adapting to network conditions.
