proposed an optimal frame size adaptation algorithm with A-MSDU under error-prone channels.
To this implemented module, we added the A-MSDU scheme.
A-MSDU scheme is used for voice being more adequate for applications that have small frame size [19].
Moreover, APS will aggregate several MSDUs to form an A-MSDU with the optimized packet length and well regardless of traffic load.
