Topic: On Algorithm Designs for Wireless Power Transfer

Speaker: Kazuya Sakai, Associate Professor, Tokyo Metropolitan University, Japan


Wireless power transfer (WPT) is now a hot topic. In this talk, I am particularly interested in algorithm designs for WPT from the computer science standpoints. To be specific, I will address the problem of wireless charger allocation for mobile social networks, where power is wirelessly transferred among users with smart devices at opportunistic contact events. To this end, First, the similarities and differences between WPT and protocol designs for data communications are illuminated. Second, the problem is formulated including assumptions, network model, wireless charge model, the optimal solution, and challenges. Third, I will propose the weighted connectivity metric to define the shortest path as well as the adaptive wireless charger allocation (AWCA) algorithm. Finally, the performance evaluation by simulations using real human contact traces is discussed.
