    Optimization and Security Analysis of Interconnected Security Control Based on Semantic of Process Communication by Bo LU, Yueming LU

    Published 2021-09-01
    “…Facing the demand of multi-domain security control in the integrated network of air and ground, to solve the problem that singleprocess regular matching restricts the performance of interconnected security gateway, the method of high-performance optimization of interconnected security control based on semantic security analysis of process communication was proposed.The interaction model of master-slave processes was described in a parallel programming language in the method.The state transition system semantics were given to accurately express the combined semantics of the master-slave processes.The security of master-slave processes in combinatorial semantics was analyzed, which ensured that the parallel running of processes had no deadlock and starvation, and was equivalent to the original regular matching.Experimental results showed that the proposed method could give full play to the advantages of multi-core hardware and reduced the context switching overhead of the scheduler.In the case of complex regular expressions, the method was an order of magnitude better than single-core running.…”

    Performance analysis of the network communication based on AMR speech coding by using NS by JIA Long-tao, BAO Chang-chun

    Published 2006-01-01
    “…Most of the VoIP systems were based on the speech codec with a fixed rate,which maked packet-loss serious,especially for continuous packet-loss.The degradation for the speech quality would be caused by the kind of packet-loss.A network communication system for preventing packet-loss was given.The performance of the system was analyzed by using advanced NS.The simulation results show that the proposed system outperforms traditional IP system over the packet-loss,average delay and subjective listening quality.…”

    Instruction flow mining algorithm based on the temporal sequence of node communication actions by Yingzhuo XIANG, Zhengguo XU, Ling YOU

    Published 2019-09-01
    “…With the situation that the content of the communication between the nodes in the network is unknown,an instruction flow mining algorithm based on the communication sequence was proposed.Firstly,by modelling the relativity of the communication actions and proposing the node communication actions model,the background communication and instruction communication actions was modelled.Moreover,FlowMine algorithm was proposed to solve such models and the convergence of the algorithm was analyzed.The algorithm estimated parameters by sampling and iteration which obtained a near optimal solution.Finally,the validity of the approach was verified by synthetic data and empirical data analysis.Experiment results show the convergence and reliable performance of FlowMine algorithm.…”

    An Empirical Study on Ad Hoc Performance of DSRC and Wi-Fi Vehicular Communications by Seungbae Lee, Alvin Lim

    Published 2013-11-01
    “…Also, it identifies important effects of messages size, message frequency, weather condition, and vehicle mobility on vehicular communications. For example, rainy weather significantly diminishes the communication range and vehicle mobility causes temporal variations in communication throughput. …”
