He has won the Best Poster award at Intel Labs Open House in 2014 for his poster on LTE using unlicensed spectrum. His survey paper on “Cooperative Spectrum Sensing” with Prof. Akyildiz is the Most Cited Physical Communications (Elsevier) Articles since 2010. He serves as a reviewer for several IEEE journals including IEEE Transactions on Wireless Communications, IEEE JSAC and IEEE Transactions on Vehicular Technology and has also served on the TPC of several IEEE conferences. His research interests are in 5G cellular systems, Heterogeneous Networks and Internet of Things. He is a member of the IEEE. .
Tutorial: Supporting Internet of Things for 5G and beyond: Requirements, Use Cases and Research Challenges
It is estimated by 2020, over 50 billion machine-type devices will be connecting to mobile networks. These devices, also referred to Internet of Things (IoT) devices, unlike human handheld smartphones, can be used in a myriad of use cases such as in transportation, eHealth, infrastructure monitoring, industrial automation and so on. Cellular networks have never faced a requirement of supporting such unprecedented number of devices. Not only the massive number of devices is a major challenges but in addition, these devices pose unique requirements from a system and network design perspective. For example, a number of these devices will be deployed in harsh environments with very limited access and therefore are highly energy constrained. Typically, they need to survive on batteries for an extended amount of time (in the order of years). In addition, some of these devices used in applications such as earthquake monitoring, vehicular communication may need to deliver time-sensitive information in a reliable manner to avoid disasters/accidents. Such diverse requirements also lead to major research challenges in preparing 5G networks to support IoT devices. This involves designing extremely narrowband channels to accommodate billions of the devices, energy harvesting techniques as well as intelligent traffic handling at the mobile edge among other approaches. In this talk, the requirements and use cases for IoT over 5G will be introduced and the limitations faced by current systems to support such devices highlighted. Then, the research challenges that need to be address to overcome these limitations and prepare the 5G networks for IoT will be presented.
