ABSTRACT: With the advent of the
wide-spread use of smart phones, video streaming over mobile wireless networks
has suddenly taken a huge surge in recent years. Considering its enormous
potential, mobile WiMAX is emerging as a viable technology for mobile TV which
is expected to become of key importance in the future of mobile industry. In
this paper, a simulation performance study of Mobile TV over mobile WiMAX is
conducted with different types of adaptive modulation and coding taking into
account key system and environment parameters which include the variation in
the speed of the mobile, path-loss, scheduling service classes with the fixed
type of modulations. Our simulation has been conducted using OPNET simulation.
Simulation results show that dynamic adaptation of modulation and coding
schemes based on channel conditions can offer considerably more enhanced QoS
and at the same time reduce the overall bandwidth of the system.
