    An Error Tolerated Congestion Control Algorithm Based on Packet Loss Rate Measurement in Deep Space Communication Network by Junrong Yan, Yulong Lu, Peng Pan

    Published 2015-11-01
    “…Congestion control algorithms of TCP protocol previously used in space communications are mostly based on TCP Vegas algorithm.They always require accurately measurement of RTT,but it's very difficult to achieve in deep space communication networks which have very long and variable delay channel characteristics.An errors tolerated congestion control algorithm is proposed based on packet loss rate measurement.The algorithm sends data in the form of data blocks and gives an errors tolerated degree based on the history data.It measures the congestion state based on the current packet loss rate measurement,so it can achieve a smaller overhead and higher transmission efficiency.In addition,the usage of mathematical modeling methods simplifies the networks and simulates the real network traffic.The mentioned algorithm is compared with the classical congestion control algorithm.Analysis and simulation prove that thethroughput of improved algorithm is 34 percent better than Tahoe and 22 percent better than Reno,so it gets a better performance.…”

    Analysis of time delay jitter of communication system on fault location of power line based on traveling wave method by Mingzhen LI, Jianming LIU, Hang WANG, Wenjun ZHOU

    Published 2018-03-01
    “…In order to study the time delay jitter of communication system on fault location of power line,a mathematical model of the delay jitter based on Poisson distribution was presented.The characteristic of the random delay jitter for single and multiple node cases were analyzed.Results show the delay jitter is remarkable when the communication load is high,and is insensitive when the communication load is low in the single node case.The total delay jitter is lower than the sum of the jitter in the queues on a path,and the position of the heavy load node in the path has a large influence on the total path jitter.The delay jitter with its influencing factors should be taken into account to perform optimal network design.…”
