Study of remote routing strategy in parallel network simulation by Yu CUI, Zhao-xin ZHANG, Hong-li ZHANG, Zhi-hong TIAN

“…The advantages and disadvantages of several remote routing strategies for parallel network simulation were studied，and a new method based on optimize-edge routers was presented.Through converting the original forwarding style of routing IP to routing ID of edge router,the mechanism increased the speed of routing lookup.Also the exploitations of the tree contraction,edge router reduction and assnode reduction in the proposed mechanism effectively decreased the memory cost.Experimental results show 85% reduction in memory use and 75% decrease in time cost for the new routing strategy,comparing with the border-based remote routing strategy in PDNS.…”

Topology restoration algorithm for heterogeneous sensor networks based on connected dominating tree by Ting-jun SHI, Xu-ming FANG, Yun YANG

“…For currently lacking the study of the topology restoration algorithm for heterogeneous sensor networks,a topology restoration algorithm for heterogeneous sensor networks based on connected dominating tree (HSNTR) was proposed.Firstly the algorithm constructed a virtual backbone forwarding data at very low cost,and secondly when a node fails,the algorithm would dynamically locally restore the backbone to make it still connect and cover all nodes.Theoretical analysis proved the maximum number of nodes the algorithm uses during constructing and restoring the backbone.Simulation analysis showed that the algorithm is better than other algorithms in terms of energy efficiency,scalability and reliability.…”

Verification on policies for network functions in SDN/NFV-based environment by Haoyu CHEN, Deqing ZOU, Hai JIN

“…Although the newly introduced SDN and NFV technologies bring flexibility and convenience in network management, the dynamic forwarding policies introduced by SDN may cause invalidation in the network function policies, and the policies in different network functions may also cause conflicts due to their own behaviors.In order to verify the policies in SDN/NFV-based cloud network, the verification on policies between the network function and the SDN device, as well as across the network functions were considered.A unified policy expression for analysis was summarized, and policy verification scheme, framework and prototype implementation were proposed to verify the correctness of polices in different scenarios, then experiments were conducted to justify the effectiveness and performance…”

Geographical information based false report filtering scheme in wireless sensor networks by Zhi-xiong LIU, Jian-xin WANG

“…A geographical information based false reports filtering scheme(GFFS)in sensor networks was presented.In GFFS,each node distributes its location information to some other nodes after deployment.When a report was generated for an observed event,it must carry not only MACs from t detecting nodes with distinct key partitions,but also locations of these nodes.Each forwarding node checks not only the correctness of the MAC and the locations carried in the report,but also the legitimacy of the locations.Analysis and simulation results demonstrate that GFFS can resist collaborative false data injection attacks and thus can tolerate much more compromised nodes than existing schemes.…”
