The Cellular Saving System in Networks Smartphone on Data offloading Energy

Abstract

In cellular networks, due to practical deployment issues, some areas have good wireless coverage while others may not. This results in significant throughput (service quality) difference between wireless carriers at some locations. Through extensive measurements, we have validated the existence of such service quality difference. Then, through peer to peer interfaces such as Wi-Fi direct, a mobile device (node) with low service quality can offload its data traffic to nodes with better service quality, to save energy and reduce delay. Through trace-driven simulations, we also show that all users can benefit from data offloading in the long run.
