Social Networking Reduces Peak Power Consumption in Smart Grid

Minimizing the peak power consumption of electrical appliances under delay requirements is shown to be NP-hard. To address this, we propose a “family plan” approach that partitions users into groups and schedules users’ appliances to minimize the peak power consumption of each group. Our scheme leverages the social network topology and statistical energy usage patterns of users. To partition […]

State abstraction and management in software-defined networks

SDN-enabled networks offer a great degree of flexibility, programmability and support for multiple applications. Applications running on top of a SDN controller could further benefit if network state information were made available to them as part of the SDN framework. Our work investigates the requirements for abstracting network state on the control plane. We intend to show […]

An extended SDN architecture for network function virtualization with a case study on intrusion prevention

In conventional software-defined networking (SDN), a controller classifies the traffic redirected from a switch to determine the path to network function virtualization (NFV) modules. The redirection generates a large volume of control-plane traffic. We propose an extended SDN architecture to reduce the traffic overhead to the controller for providing NFV. The extension includes two-layer traffic classification […]

Understanding social effects in online networks

Understanding the motives behind people’s interactions online can offer sound bases to predict how a social network may evolve and also support a host of applications. We hypothesize that three offline social factors, namely, stature, relationship strength, and egocentricity may also play an important role in driving users’ interactions online. Therefore, we study the influence […]
