Abstract: Wireless energy charging using mobile vehicles has been a viable research topic recently in the area of wireless networks and mobile computing. This paper gives a short survey of recent research conducted in our research group in the area of collaborative mobile charging. In collaborative mobile charging, multiple mobile chargers work together to accomplish a given set of objectives. These objectives include charging sensors at different frequencies with a minimum number of mobile chargers and reaching the farthest sensor for a given set of mobile chargers, subject to various constraints, including speed and energy limits of mobile chargers. Through the process of problem formulation, solution construction, and future work extension for problems related to collaborative mobile charging and coverage, we present three principles for good practice in conducting research, that is, select a simple problem, find an elegant solution, and use imagination for extension.

Abstract: As the largest Chinese language search engine, Baidu operates hundreds of thousands servers and network elements. Besides the Search offering, Baidu maintains an eco-system including thousands of products and services developed by Baidu and its partners. The scale of the computing, storage and networking needs always outpaces the resources that can be provisioned in timely manners. Therefore, there are strong driving needs for Baidu to develop the Quality of Service solutions with a systematic approach, leveraging the most advanced technologies from the industry and adopting the best current practice from the Internet operators. In this talk, I will give an introduction of our needs, our methodologies and some of the engineering solutions implemented or being implemented. I will also share some of our observations about how to operate network QoS of an infrastructure at the Internet scale.
