Abstract: | : | Ubiquitous connectivity and sensing are among the grand challenge
problems for next generation wireless systems, 5G and beyond. However,
limitations exist in terms of resource management or infrastructure
deployment (e.g., cell towers, IoT sensors etc) that hinders the
realization of true ubiquity in various contexts. Often these
deployments need to be on-demand, quick and temporary in order to
avoid over-provisioning and maintenance costs. Recent advances in
unmanned aerial vehicle (UAVs) technology or drones have the potential
to change the landscape of wide-area wireless connectivity and sensing
by bringing a new dimension – “mobility†to the network infrastructure
itself. I will demonstrate how drones can add a great value to
state-of-the-art communication and sensing systems, particularly when
such infrastructure are compromised (natural disasters), in-accessible
(security threats), sparingly present or non-existent (rural areas).
Our aim is to design a robust networked system that helps in effective
communication and coordination among people (e.g., emergency
responders) in such scenarios. In the first part of the talk, I will discuss how drones can be used as “flying†cellular base stations providing connectivity to clients on the ground. We will see how the position of the drone in 3D aerial space is critical in determining the overall connectivity to the clients located on the ground. Given the drone’s limited flight time, we explore how to quickly search for a near-optimal spot for the drone to operate at, optimizing the capacity of the wireless radio access network (RAN). In the second part, we will learn how the drones can also be used to localize such mobile clients in GPS-denied environments without access to any pre-deployed localization infrastructure. Overall, our contributions enhance the 5G’s vision for ubiquitous connectivity by providing on-demand support for connectivity and sensing in challenged environments.

He is broadly interested in designing mobile systems that interact with and interpret the physical world, spanning both algorithm design as well as system prototyping. He has held several internship positions at Bell Laboratories, Hewlett Packard Laboratories and Huawei Technologies leading to longer term collaborative efforts. He has regularly published in reputed venues for systems and networking including Infocom, NSDI, Mobicom, CoNext, etc. and was nominated for the best paper award at ACM Sigcomm IMC 2014. In 2011, Ayon finished his B.E. in Computer Science and Engineering from Jadavpur University, Kolkata where he was awarded the department gold medal/best project award. He is also a recipient of the DAAD WISE fellowship in 2010. |
