What is MOS Value

Introduction to MOS Value:

MOS value indicates the overall quality of the voice line and in general this value ranges from 0 to 5, where 0 indicates poor quality and 5 indicates excellent quality of voice. This particular value is calculated for the three scenarios and the corresponding comparison graph is as shown below

From the above graph it is clear that, the average MOS value is more when the routing protocol is AODV. The average MOS value is more at the beginning of the simulation and later it was reduced for all the three scenarios due to the wireless LAN server behavior.

But when the average values are considered the quality of the voice line is more with the case of AODV and it is reduced with the case of DSR. From the overall analysis it is clear that, to enhance the MOS value of the voice application AODV is best suited routing protocol.
