Abstract: Mobile networking research has historical not benefited much from input from the academic research community. There are a number of reasons for this state of affairs. First, the mobile networking domain is inherently complicated and has historically been primarily driven by extended standardization efforts by telecom vendors and providers. Second the relative scarcity of practical research work in this space is the direct result of a lack of access to realistic experimental platforms to enable research and experimentation. Third, historically there has been a lack of open source mobile networking stacks, which effectively constrained research in this space to well funded industrial labs. We argue that mobile networking research is poised to break out of this traditional model: First, the impact on networking of the various “soft” technologies (software-defined-networking, cloud computing, software-defined-radio, network function virtualization) is likely to extend into the mobile networking space. Second, initiatives by funding and regulatory agencies, e.g., by the FCC ![3] and the NSF ![1], are attempting to enable more experimentation and innovation and the realization of new business models in the mobile networking space. Third, over the last couple of years, viable open source mobile networking stacks have emerged which enable experimental work in this space [4, 5]. Finally, experimental testbeds focused on enabling research in the area of mobile networking are available [1, 2]. To help foster this breakout, in this Webinar we will introduce attendees to the !PhantomNet testbed ![2]. !PhantomNet is a remotely accessible mobile networking testbed with a range of hardware and software components to enable a broad range of mobile networking research. We will describe the capabilities of !PhantomNet and walk attendees through the realization of a basic 4G network in the testbed. Attendees will be pointed to material that would allow them to perform this on their own. We will also briefly cover our future plans as well as other !PhantomNet features.
