M2M Protocols for Constrained Environments in the Context of IoT: A Compariso...Edielson P. Frigieri
The Internet of Things movement opens new possibilities for services and business along with new technological challenges, such as power efficiency, operation in constrained environments, security, and privacy. With the expectation of a high amount of devices connected in this Future Internet, scalability is also assumed to be a challenge. To address these limitations, several protocols are being proposed. In this paper, two of them, MQTT and COAP, are presented and qualitatively compared, summarizing their main features and limitations, highlighting the best scenarios where each approach is more suitable.

Frame counting: achieve accurate and real-time link estimation for low power ...Daibo Liu
Link estimation is a fundamental component of forward- ing protocols in wireless sensor networks. In low power forwarding, however, the asynchronous nature of widely adopted duty-cycled radio control brings new challenges to achieve accurate and real-time estimation. First, the repeat- edly transmitted frames (called wake-up frame) increase the complexity of accurate statistic, especially with bursty chan- nel contention and coexistent interference. Second, frequent update of every link status exhausts the limited energy sup- ply due to long duration of beacon broadcast.
