A Distributed Caching based on Neighbor Cooperation in CCN

Abstract

Content Centric Network is a clean-slate future Internet architecture, which is centered around content distribution. The In-network caching is the main feature of the new network paradigm. However, the default strategy which leaves cache everywhere in CCN results in serious cache redundancy among neighbor nodes. In this paper, we pro pose a Neighbor Cooperation Caching Strategy to tackle the redundancy problem. Our strategy includes a real time strategy called Cooperative Redundancy A voidance and a non-real time strategy called Cooperative Redundancy Elimination to reduce neighborhood redundancy. Our si mulation results show that our approach can effectively reduce reduplicate caches between neighbor nodes to im prove neighborhood cache utilization, as it achieves good performance in improving cache hit and reducing access delay.

Distributed Caching in Wireless Cellular Networks Incorporating Parallel Processing

“…Consider the deployment of cache devices with the installation of new network facilities such as cellular base stations, the optimal selection of locations becomes essential. Cooperative caching techniques have been discussed in [15]. However, huge challenges emerge with the increasingly complicated network topology.…”
