The explosion of mobile data traffic has an adverse effect on communication delay and system performance in 5G wireless network. Deploying a number of caches on the base stations(BSs) to cache content has became an essential solution. In this paper, we present a caching structure and propose a CMAC(Cooperative Multicast-Aware Caching) strategy to reduce the average latency of delivering content. The...
The use of packet filters has increased considerably due to the growth of Internet users and network services. A number of header fields must be examined by the filter, causing delay for each packet processed. The problem is compounded when considering multiple filters across a network. To maximize network performance, it would be desirable to minimize the number of packet filters for each path across...
In this work, we propose a bidding policy for cloud users to reduce the instance rental bill by using the spot instance. Our approach is based on the recently developed two-timescale Lyapunov Optimization framework. It is shown that our approach is effective to save the instance rental cost.
