The Probability Distribution Modeling and Parameter Estimation Method of ROD in Different Packet Loss Pattern for Heterogeneous Network

The packet loss differentiating mechanism of TCP for heterogeneous network has the important influence to the stability of wireless network, relative one-way delay (ROD) of loss pair is adopted as a differentiating parameter to distinguish the loss type in reference [1]. The accuracy of this algorithm depends on ROD membership function. In order to differentiate packet loss pattern more accurately, first the probability distribution of ROD is analysed in different packet loss pattern, then the probability distribution model is built, finally the method of parameter estimation is proposed. From the effect of this method model is results of simulation the effect of this method model is more ideal.
