Towards Pervasive Heterogeneous Wireless Access at the Edge

With over 6 billion cellular mobile devices in use today, the Inter- net is fast approaching an inflection point where the number of mobile devices far exceeds the number of fixed hosts and servers. Wireless access is not only limited to cellular or Wi-Fi connectivity through hand-held smart devices, but also includes a variety of wire- less sensors, Internet-of-Things (IoT), and smart-vehicle to vehicle (V2V) communication. Such ubiquitous wireless access scenarios pose architectural challenges to the existing TCP/IP based Internet framework, which has not undergone any major change since its inception. This work aims to support flexible wireless access to mobile devices in the future Internet, based on the MobilityFirst future Internet architecture, now under development. Mobility- First provides a clean-slate solution to emerging wireless access characteristics such as temporary disconnections, varying link qual- ity, mutlihoming and multicasting and provides a unified network framework that supports a wide range of mobile access scenarios. In our research, we focus on building key MobilityFirst protocol components such as routing support both intra and inter-domain for multihoming, efficient multicasting as well as low overhead and low latency protocols for smart resource-limited devices such as IoTs. These protocol designs are then evaluated for representative wireless/mobile use cases.
