James Pope receives Phd in Information Technology


Doctor of Philosophy candidate James Pope presents dissertation paper “A CONTROL PLANE FOR LOW POWER LOSSY NETWORKS” on Monday, August 29th, 2016. Dr. Pope’s research is in the area of low power, lossy wireless networks (LLNs). LLNs are becoming a critical infrastructure for future applications that are ad-hoc and untethered for periods of years.

The applications enabled by LLNs include Smart Grid, data center power control, industrial networks and building and home automation systems. LLNs intersect a number of research areas to include the Internet of Things (IoT), Cyber Physical Systems (CPSs) and Wireless Sensor Networks (WSNs). A number of LLN applications require quality of service guarantees, such as industrial sensor networks. These applications are not currently supported by standardized LLN routing protocols that allow dynamic changes in the network structure, specifically IPv6 based Routing Protocol for Low-Power and Lossy Networks (RPL).

Pope developed the CREST: Coordinated Routing for Epoch-based Stable Tree (CREST) control plane infrastructure to address this problem using an epoch-based framework, allowing better quality of service guarantees by providing a stable routing tree. The framework assumes efficient and reliable information collection and dissemination mechanisms. Using a medium sized LLN, I showed that the control plane was successful in allowing an example application that requires a stable routing tree to maximize the application’s goal.
