Wireless Cooperative Caching System 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 firstcomefirstserved (FCFS) to choose the winning bids and allocate rewards to UTs. In this demo, we present displays on PC and mobile phones.

Cooperative and Distributive Caching System for Video Streaming Services over the Information Centric Networking This work presents a cooperative and distributive caching system over the informationcentric networking (ICN) tree. The goal of the proposed caching system is to provide seamless video streaming services with high network utilization over the ICN tree. The proposed system employs a metafile made by a scalable caching scheme for simple but effective Content Store (CS) management, and the caching information among ICN nodes is delivered by modified ICN interestdata packet headers with no additional control overhead. Based on the delivered caching information and the metafile, each ICN node determines its own caching chunks in a distributive way to minimize the required peak bandwidth for seamless streaming. The proposed caching system is fully implemented using the NDNSim for large scale simulation. Moreover, a smallscale real cellular wireless network testbed is realized by using CCNx and Raspberry PIs.
