In a crowdsourcing system, it is important for the crowdsourcer to engineer extrinsic rewards to incentivize the participants. With mobile social networking, a user enjoys an intrinsic benefit when she aligns her behavior with the behavior of others. ...
Betweenness Centrality Based Software Defined Routing: Observation from Practical Internet Datasets
Software-defined networking (SDN) enables routing control to program in the logically centralized controllers. It is expected to improve the routing efficiency even in highly dynamic situations. In this article, we make an in-depth observation of ...
A Pure Visual Approach for Automatically Extracting and Aligning Structured Web Data
