Differential Game for Distributed Power Control in Device-to-Device Communications Underlaying Cellular Networks
In the formulating of power control for wireless networks, the radio channel is commonly formulated using static models of optimization or game theory. In these models, the optimization programming or static g...

Simultaneous mobility of data sources and content requesters in content-centric networking
Content-Centric Networking (CCN) is proposed as a new communication paradigm in which the content is accessed by the name instead of IP address with the benefit of mobility support. Although the mobility of th...

Base station association schemes to reduce unnecessary handovers using location awareness in femtocell networks
In this paper, we propose a predictive scheme to generate reduced neighbor lists. In addition, we formulate a predictive association game. The game is designed to determine an optimal base station for maximum ...
