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 […]

A feasible method to combat against DDoS attack in SDN network

In Software Defined Network, the controller is so vulnerable to flooding attack. By injecting spoofed request packets continuously, attackers make a burdensome process to the controller, cause bandwidth occupation in the controller-switch channel, and overload the flow table in switch. The final target of attackers is to downgrade or even shutdown the stability and quality of service […]

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 […]
