Research on cooperative caching in mobile P2P network
Ji Meili, Xinhua Wang · Computer Engineering and Applications Journal · 2012
This paper deploys P2P system in mobile campus network and then presents an effective cooperative caching strategy. Access control strategy usesthreshold valueand relationship of location between two nodes to select the data to be cached. Cache replacement strategy chooses the data which will be replaced by theCostfunction that is decided by three factors: data popularity, data size and distance between two regions. Data consistency strategy combines benefits of Plain-Push and Pull-Every-time and then makes improvements. Two sets of simulation experiments show that cooperative caching strategy achieves better performance in terms of reducing latency, decreasing overhead of network communication and improving the hit ratio.
