  Quality of Service (QoS) is now regarded as a requirement for all networks in
managing resources like bandwidth and avoidance of network impairments like
packet loss, jitter, and delay. Media transfer or streaming would be virtually
impossible if QoS parameters were not used even if the streaming protocols were
perfectly designed. QoS Scheduling classes help in network traffic optimization
and the priority management of packets. This paper presents an analysis of QoS
scheduling classes using video traffic in a MANET. The main objective was to
identify a scheduling class that provides better QoS for video streaming. A
simulation was conducted using NetSim and results were analyzed according to
throughput, jitter, and delay. The overall results showed that extended
real-time Polling Service (ertPS) outperformed the other classes. ertPS has
hybrid features of both real-time Polling Service (rtPS) and Unsolicited Grant
Service(UGS) hence the enhanced performance. It is recommended that ertPS
scheduling class should be used in MANET where QoS consideration is utmost
particularly in multimedia streaming applications.
