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 Boots memory, and low power.IETF CoAP and HTTP are used to monitor or control environments in Internet of Things (IoT) and Machine-to-Machine (M2M
