Wireless Cooperative Caching System

Abstract

In this paper, we introduce a wireless cooperative caching system (WCCS) to reduce the cost of both operators and users and also improve the quality of experience (QoE) of users. In this system, an intelligent routing relay (IRR) assigns a list of popular services and user terminals (UTs) can cache these services with their own cellular network traffic. When UTs upload these cached services to the IRR, they can obtain rewards. The other users can then access the IRR to get the cached services at a faster rate and get better QoE. The cellular network operators can save spectrum resource while they just deliver one copy of services. In order to encourage users to upload, we use reverse auction and first-come-first-served (FCFS) to choose the winning bids and allocate rewards to UTs. In this demo, we present displays on PC and mobile phones.
