In this article, we highlight the distinctive features of a feasibility study, identify the main objectives and guiding questions of a feasibility study, and illustrate the use of these objectives. We synthesized the research methods literature related to feasibility studies to identify five overarching objectives of feasibility studies that focus on social and behavioral interventions. Feasibi...

Today wireless networks are increasingly used to perform applications with Quality of Service constraints (QoS) such as delay, delivery ratio, and channel reliability. Especially, as demand for real-time transmissions increases, transmitting packets with hard delivery deadlines poses an important network control problem. In this thesis, we propose a framework for characterizing feasibility regi...
