H.263 Video Transmission in Wireless Local Area Networks using OPNET

Digital video transmission in wireless environment comprises major challenge. Most of the video applications are delay sensitive and have relatively higher bandwidth requirements. Time-varying and asymmetric propagation proOerties of wireless links pose major challenge to low delay and ideally error-free transmission. Studies [1-4] suggest hybrid schemes, optimized control mechanisms or capability of WLANs to adapt to dynamic conditions of wireless link for video transmission. The variable nature of resources in a radio environment requires video clients also to adjust accordingly. Unlike studies [1-4], this work has been carried out to study the effect of mobility and mobility patterns on H.263 coding standard based video streaming in an IEEE802.11b WLAN. Numerous simulations, with different set of parametric settings, were performed using H.263 video traffic. Study results in verification of successful H.263 video traffic import in OPNET and some recommendations to make video clients in WLAN some what more intelligent by adapting to the variations in network resources due to mobility.
