Abstract-Connected devices offer tremendous opportunities. However, their configuration and control remains a major challenge in order to reach widespread adoption by less technically skilled people. Over the past few years, a lot of attention has been given to improve the configuration process of constrained devices with limited resources, such as available memory and absence of a user interface. Still, a major deficiency is the lack of a streamlined, standardized configuration process. In this paper we propose EC-IoT, a novel configuration framework for constrained IoT devices. The proposed framework makes use of open standards, leveraging upon the Constrained Application Protocol (CoAP), an application protocol that enables HTTP-like RESTful interactions with constrained devices. To validate the proposed approach, we present a prototype implementation of the EC-IoT framework and assess its scalability.

Abstract-As the Internet of Things continues to grow rapidly in the coming years, the number of devices with limited resources will continue to grow as well. These so-called constrained devices typically implement specialized protocols and data formats for increased efficiency. While this reduces the load on constrained devices, it also limits the usability of such devices for their users. This paper presents a HTTPCoAP proxy for improving the usability of constrained devices that implement embedded web services. This is accomplished by rendering user interfaces and solving naming and routing issues. As a result, the user experience of highly-optimized embedded web services is similar to that of conventional web services. By means of small-scale experimentation, the presented approach is evaluated functionally and the usability is evaluated in terms of user interface responsiveness.

Because of the recent advances in wireless technologies and, consequently the fast growing number of wireless devices that are being deployed in consumer houses, there is a growing demand from manufacturers to develop and deploy tools able to diagnose problems and evaluate the performance of their products prior to releasing them to the market. Such testing tools are required to be quickly deployable in real-life home environments and should support various wireless technologies and use cases. In order to avoid future product service failures and costly complex troubleshooting, the results should offer a full understanding of the product behavior on the field. Different approaches able to fulfill these objectives have been proposed in literature. In this paper, we propose a new portable and highly flexible testbed tool to evaluate the performance of wireless devices in consumer houses. Furthermore we demonstrate the feasibility and operation of the testbed in two real-life home environments for assessing the impact of range extenders on wireless communication performance.
