Application of Chebyshev Delay Estimation Algorithm In Mobile Phone Network Failure Detection

摘要:

对手机网络失效检测是一个新的研究课题。手机网络的失效往往没有明显特征,内部体现为消息的滞后性；根据这一特性,提出一种契比雪夫滞后估计算法并应用到手机网络失效检测中,给出了算法的原理,并根据手机网络传递消息滞后时间,带入算法进而估计下一次信号消息到达的滞后时间估计值,根据手机网络中消息到达的时间间隔,代入算法估计下一个数据消息可能到达的滞后间隔；设置下一个信号消息到达时刻计时器的超时值,将低于该超时值的滞后时间间隔所对应的手机网络消息节点看成失效节点,实现了对手机网络失效的准确检测；实验及分析说明该算法的估计结果同实际手机运行情况匹配度超过85%,具有较高的鲁棒性。

Abstract:

Failure detection for mobile network is a new research subject. The failure of the mobile phone networks tend to have not more sexual characteristics, internal embodied in news of hysteresis. According to this characteristic, a message delay estimation algorithm is proposed and applied to the mobile phone network failure detection, the principle of the algorithm is presented, and according to the mobile phone network message delay time, into the algorithm to estimate the next message signal to estimate of the time lag, according to the news in the mobile phone network to reach the time interval, substitution algorithm to estimate the next data message may reach the lag intervals. Settings of a signal message arrives at the moment the timer timeout value, the lag time interval will be lower than the timeout value as the failure of the mobile phone network message node, realizes the accurate detection of the mobile phone network failure. Experiment and analysis show that the algorithm estimates the results with the actual phone operation matching degree is more than 85%, has high robustness.
