To improve the robustness of video transmission over heterogeneous wireless network various error resilient tools are deployed. The impact of bit errors on the perceived video quality depends on several factors, such as error resilience of the data format, error concealment mechanism used and characteristics of the bit error pattern. In this paper the(More)
Digital video transmission using wireless technology is an important functionality in multimedia communication. Such wireless transmission considers various parameters of channel like reliability, quality of service (QoS), transmission rate, transmission delay etc. User datagram protocol (UDP) is a fast transmission protocol used by most of the real-time(More)
Amendments in 802.11n have opened doors to variety of methods to stretch data rates up to 600Mbps. These include spatial diversity, spatial multiplexing both feasible due to MIMO channels, frame aggregation, block acknowledgements, smaller guard interval, channel bonding etc. This paper discusses adaptive framework using of these techniques for efficient(More)
Quality of Service (QoS) optimization is an important design goal in wireless video transmission. The application (APP) layer 802.11e medium access control (MAC) layer, and physical (PHY) layer of the wireless protocol stack can be jointly designed for the exchange of information. This will optimize the performance of wireless network for real-time digital(More)
For real time digital video transmission, an innovative multi-layer design of wireless systems is needed, where information among layers is exchanged and parameters are jointly optimized for richer interfaces among the layers of the protocol stack. The growing prevalence of wireless calls for such design of wireless network to support Quality of Service(More)
