Connecting wireless sensor networks (WSN) to the Internet, and subsequently making it part of the Internet of Things (IoT), unleashes its full potential by facilitating remote services. WSN-IoT offers a virtual layer that provides information about the physical world accessible through various computational devices. The study of quality of service (QoS) in the domain of WSN-IoT brings forward potentials and challenges, especially due to cost and scalability limitations in physical testbeds and low credibility of simulation results. In this paper, a system architecture of a testbed with Quality of Service as a service (QoSaaS) is proposed. QoSaaS testbed concept provides an avenue for a flexible experimentation system which is capable of reacting to dynamic changes of network conditions. By employing network simulator tools to derive the network performance information based on historical data of a physical testbed, realistic prediction of network performance can be made, and adjustment to the physical network can be proposed. This paper reports the preliminary experiences of implementing an organization for encouraging QoSaaS. The paper also discusses the ongoing and potential directions of the work.
