Abstract:
Offloading mobile data traffic away from cellular networks has
become a main concern for mobile operators to guarantee the 
quality of service of various applications offered to end-users. 
Given the explosive growth of smartphone users and mobile data 
traffic, it is crucial to develop efficient and scalable mechanisms 
to meet the increasing demand of network capacity. To address 
the challenge, we propose the Network-Assisted Offloading (NAO), 
a framework that utilizes network assistance to promote offloading 
performance and energy saving on mobile hosts. We advocate that an 
efficient, simple to deploy, and with absolutely minimal or no changes 
to an end host solution is the key to achieving effective
offloading in current and future mobile networks. Compared to solely 
host-based solutions, our approach explores a new angle to address 
the offloading challenge through network assistance.
