Computationally efficient E-model improvement of MOS estimate including jitter and buffer losses

Traffic Management by Admission Control in IMS Networks

“…In comparison with the measured sum method, the number of accepted connections is 46, which is half of the accepted connections by the measured sum method. PRA method is basically the opposite of the measured sum method [14]. It is caused by the fact that the PRA method allocates the capacity at the level of peak bit rate for every source.…”

“…An interval, which is too small can cause a nonobjective decision-making. If we include all samples, computational difficulty would be very high [14,15]. Dynamical sliding of the measured interval solved this problem.…”

Multihoming aware optimization mechanism

“…In addition, due to its non intrusive nature, it is employed in several works assessing VoIP quality [Li, 2010;Gong, Qipeng and Kabal, Peter, 2011;Halas et al, 2012]. The E-model has been adapted to IP networks [Cole and Rosenbluth, 2001], where the R factor is based on I d -delay and where H(x) is a unity or step function, as such H is 0 if x ≤ 0 otherwise H is 1.…”

“…Equation 4.27, where besides packet loss, jitter buffer size and network jitter are included [Halas et al, 2012;Voznak et al, 2012].…”

A new mobile audio quality assessment using Jitter Distortion Measure approach

“…In 2011, Adrian et al [16] proposed a jitter buffer stochastic model which is incorporated into E-model in an additive manner accounting for network jitter effects. In 2012, Halas et al [17] also improve ITU-T E-model MOS estimate of VoIP call quality including jitter buffer size, codec packetization and network jitter.…”
