OSU's networking group is engaged in multiple ground-breaking projects based on innovative ideas at the juncture of the physical and cyber worlds. The projects span a wide range of applications that include sensor networks, vehicular networks and the smart-grid. We are exploring how RFIDs and sensors attached to physical objects such as key-chains and household appliances, and equipped inside buildings, can change the way we interact with our physical world. For deeply embedded battery-powered sensor networks, we are developing machine learning techniques that support detection, classification, and tracking of humans and animals in complex urban and forest settings. In the vehicular networks area, we are investigating how vehicles can intelligently navigate by leveraging capabilities to communicate and collaborate. We are designing solutions for improved positioning of vehicles, developing mechanisms for accurate vehicle identification and designing systems for supporting safety-critical applications. The Smart-grid is the next generation of the power-grid that allows the integration of increasing intelligence into the operation of the power grid, both at the supply and demand ends. At the supply-end, renewable energy generation allows end-customers to also act as suppliers. At the demand-side, smart appliances provide new means of controlling the load exerted on the power grid within suitable range of flexibilities. Our overarching objective is to develop the analytical foundations and design tools required to build an efficient, reliable, and resilient future electric grid. Hence, we are designing breakthrough control, market, and incentive regulation mechanisms to manage the unique dynamics and incentives of the smart grid. We are also investigating how networking elements of the smart-grid can be used to redistribute energy such that the end-user is lowered while maintaining a healthy competition among all suppliers.
