Node centrality metric based caching mechanism in content-centric network by Yue-ping CAI, Jun LIU, Xin-wei FAN

“…In order to reduce the cache redundancy as well as increase the cache hit ratios in content-centric networks,the node centrality metric based caching mechanism (CMC) was proposed.CMC utilized controllers to obtain the topology of the whole network and the idle rate of cache space.According to the connection relation of the topology,the degree centrality,closeness centrality and betweenness centrality of nodes were calculated.When CMC choose the caching nodes,it took the three metrics and the idle rate of cache space into account.Simulation results show that CMC can effectively increase the cache hit ratios and reduce the content fetching hops and average request delay compared with the traditional routing algorithms in CCN.…”

Cache allocation policy of service contents along delivery paths for the smart collaborative network by Bo-hao FENG, Hua-chun ZHOU, Hong-ke ZHANG, Ming-chuan ZHANG

“…A cache allocation policy(CA)of service contents along delivery paths was proposed for the smart collabora-tive network.CA allocates on-path caches to service contents based on their popularity,expecting to fully and efficiently utilize the cache resource along the delivery path and further improving the network performance.The performance of proposed policy CA was evaluated under a 5-layer tree topology and a 279-node real network topology.The results show that CA outperforms others in terms of tested performance indexes.Compared with LCE(leave copy everywhere)used by named data networking(NDN),CA reduces the distance that users fetch service contents over 20%.…”

Improving community structure strategy for efficiently enhancing Internet transmission performance by Jun CAI, Shun-zheng YU

“…An efficient weakening community structure strategy (WCS) by adding links to the existing networks was propose,which could enhance Internet transmission performance.Internet topology reconstruction could be realized by WCS strategy,because lightpaths that represent logical links between nodes could achieve the same high performance as physical links by means of optically bypassing intermediate nodes.The performance of the proposed strategy was investigated in pseudo random networks with community structure scale-free network with community structure and Internet,topology respectively,for both local routing strategy and global shortest-path routing strategy.The experimental results show that the traffic capacity of networks and the average shortest path are considerably improved by adding a few links among communities.…”

The Intertemporal Evolution Model of Enterprise R&D Cooperative Network by Rongguo Qiu, Yutong Wang, Tingqiang Chen

“…Results show that (1) when the R&D network evolution reaches a stable state, the joint distribution of stock knowledge and the number of cooperative enterprises do not affect the initial R&D network topology. However, the evolution path of the enterprise R&D network is complicated by the initial R&D network topology. (2) Among the three factors through which enterprises make decisions, if the enterprise values previous history highly, then the stock knowledge in a steady state will dissipate; if the enterprise values reputation highly, then the stock knowledge in a steady state will decrease but always above a threshold; if the enterprise values attractiveness highly, then the stock knowledge in a steady state can rise to a high level. …”
