Summary

My research lies in the interdisciplinary area among networking, communications, and economics. My past works include the studies of (1) cellular and Wi-Fi integration and (2) public Wi-Fi economics. The details of these studies are as follows.

1. Cellular and Wi-Fi Integration

alt text 

As the two major wireless communication technologies, cellular and Wi-Fi technologies have several complimentary features: cellular networks could provide good coverage and achieve high spectral efficiency, while Wi-Fi networks have low deployment and operational costs. With the unique characteristics of cellular and Wi-Fi networks, the mobile network operators can switch users' traffic between these two types of networks based on the real-time system conditions to optimize the system performance. In particular, we study the following two problems: (a) the mobile network operators offload the cellular traffic to Wi-Fi networks to reduce the system power consumption, and (b) the mobile network operators onload the Wi-Fi traffic to cellular networks (e.g., LTE unlicensed networks) to increase the system spectral efficiency.

2. Public Wi-Fi Economics

alt text 

There have been an increasing number of Wi-Fi networks in the public areas worldwide, such as shopping malls, restaurants, and stadiums. The public Wi-Fi networks have moved beyond their traditional roles of alleviating the mobile traffic congestion and providing the high-quality mobile services. For example, the venue owners can provide various location-based services and the advertisers can broadcast their advertisements in the public Wi-Fi networks. We design efficient economic mechanisms to motivate the cooperations among different entities on the public Wi-Fi deployment and operation. In particular, we study the following two problems: (a) the mobile network operators cooperate with the venue owners to deploy the public Wi-Fi networks, and (b) the venue owners cooperate with the advertisers to monetize the public Wi-Fi networks.
