The U.S. electrical power grid is going through a major transformation from the traditional centralized, failure prone system to an intelligent, resilient, and less-centralized grid that facilitates two-way flow of energy and information. The smart grid is conceived to have the ability to adopt technologies covering the areas of sensing, wireless connectivity, pervasive computing and adaptive control to significantly improve the efficiency. Tremendous amount of data is being used by different utilities today in the U.S. This led us to explore new spectrum bands and better spectrum management beyond what is available today. In this paper, we analyze various schemes that use the IEEE 802.11af TV white space (TVWS) spectrum to employ power saving channel access mechanism. We also propose a smart real-time power update algorithm with minimal power overhead using the TVWS. Next, we implement a MAC layer scheduling algorithm for wireless Community Area Network (CAN) system to reduce collision rate and transmission delay of smart meters to a utility base station in a neighborhood. Through detailed simulations, we show that the proposed scheme offers intelligent real-time power updates to power facilities with minimal power overhead.

Wireless technologies are nowadays being considered for implementation in industrial automation. However due to strict reliability and timeliness requirements of time-critical applications, there are many open research challenges for the merger of wireless technologies with the industrial systems. Although many medium access and control (MAC) protocols are proposed in recent years, a coherent effort on both the physical (PHY) and MAC layers is needed. In this paper, we propose a protocol termed as multiple equi-priority MAC (MEP-MAC) which combines the functions of MAC and PHY layers: the MAC layer ensures a deterministic behavior of the system by assigning priorities to the nodes, while non-orthogonal multiple access (NOMA) at PHY layer enables multiple nodes of equal priorities to simultaneously gain the channel access and transmit data to the gateway. We adapt a discrete-time Markov chain (DTMC) model to handle multiple nodes of equal priorities and perform the analytical analysis of the proposed protocol. The results show that the proposed protocol can provide up to 70% and 40% improvement in terms of system throughput and latency respectively as compared to a system that does not leverage NOMA at PHY layer.

The amalgamation of information and communication technologies in power industry has led to a revolution known as smart grid (SG). The energy consumers interact with the power utility using a bidirectional communication channel for energy trading in SG ecosystem. However, the traditional energy trading mechanisms strongly rely on trusted third parties which act as a single point of failure. Therefore, it is important to equip SG with a decentralized and secure energy trading system which can execute contracts and handle negotiations among various trading parties. Hence, in this paper, EnergyChain, a blockchain model for storing and accessing the data generated by smart homes in a secure manner is proposed. EnergyChain works in following phases: 1) a miner node is selected on the basis of power capacity of various smart homes, 2) a block creation and validation scheme is presented, and 3) a transaction handling mechanism is designed for secure energy trading. After evaluation, the superiority of EnergyChain is validated. The results obtained show that EnergyChain outperforms the traditional scheme in terms of communication costs and computation time.

Cities have been incorporating new technologies for several years, but lately the rate of technology adoption has increased and cities around the world are becoming connected and smarter. Furthermore, plethora of networking technologies and connectable devices made it more convenient to build smart ecosystems and connected commodities that can help us predict the Smart Cities to become reality very soon. The key applications could be ranging from Smart Campuses for education, connected Hospitals for better treatment and medical information sharing among doctors & patients, Smart Watering & Gardening systems at the city level to reserve natural resources, smart fishing, Smart & connected transportation systems, and many more to name. Moreover, Internet of Things (IoT) can bring noticeable efforts to connect various entities yet those efforts are prone to cyber-attacks. Likewise, every new technology and innovation brings new challenges and problems. In this workshop, we are focusing on networking and cybersecurity-related problems that currently affect or will affect cities in general around the world, whether considered smart or not. These problems would impact the city government, residents, and the businesses and other organizations that conduct business there. Keeping in mind the new technologies and life in a smarter city, let’s consider what could happen if one or more technology-reliant services don’t work. What would be commuting look like with non-functioning traffic control systems, no street lights, and no public transportation? How would citizens respond to an inadequate supply of electricity or water, dark streets, and no cameras? What if garbage collection is interrupted in summertime and stinks up the streets? We believe, it would be unpleasant and cause a lot of chaos in any city.
