【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]:The detection of mobile phone network failure is a new research topic. The failure of mobile phone network often has no obvious characteristic, and the interior is reflected in the lag of message. According to this characteristic, a Chebyshev delay estimation algorithm is proposed and applied to the mobile phone network failure detection. The principle of the algorithm is given. And according to the delay time of the mobile phone network message delivery, the algorithm then estimates the delay time of the next signal message arrival, and according to the time interval of the message arrival in the mobile phone network, The algorithm estimates the delay interval that the next data message may reach, sets the timeout value of the next signal message arrival time timer, and treats the mobile phone network message node corresponding to the lag time interval below the time-out value as a failure node. The experiment and analysis show that the estimation result of the proposed algorithm is more than 85 and has a high robustness to the actual mobile phone operation.
