“…For instance, VoIP scheduling for WiMAX networks was studied [23,24]. Haghani et al [25] considered MPEG video scheduling in WiMAX networks. In that study, the authors used MPEG characteristics to differentiate among MPEG frames such as I, P, and B frames.…”

“…There is work on the video traffic modeling in a wireless environment with emphasis on the streaming video over WiMAX networks [27]. The I, P and B frames have been modeled separately according to their types, and a fixed pattern is used to combine these frames together to form the GOP (Group of Picture) [27][28][29]. A video traffic model was obtained using a trace generated with a fixed frame inter-arrival time [30].…”

This paper reports on the design of an OPNET simulation platform to test the performance of sending real-time safety video over VANET (Vehicular Adhoc NETwork) using the WiMAX technology. To provide a more realistic environment for streaming real-time video, a video model was created based on the study of video traffic traces captured from a realistic vehicular camera, and different design considerations were taken into account. A practical controller over real-time streaming protocol is implemented to control data traffic congestion for future road safety development. Our driving video model was then integrated with the WiMAX OPNET model along with a mobility model based on real road maps. Using this simulation platform, different mobility cases have been studied and the performance evaluated in terms of end-to-end delay, jitter and visual experience.

“…It should be noted that decoding of a P frame within a GoP is dependent upon an I frame within the same GoP and decoding of a B frame within a GoP is dependent upon an I and P frames within the same GoP. The loss of a higher priority frame within a GoP results in the loss of other dependent frames within the same GoP [5]. Even when the video stream is compressed, it still requires large bandwidth.…”
