Application Layer Delay-centric Handover of Streamed Video in a 4G Network
نویسندگان
چکیده
In the currently proposed schemes for performing a vertical handover between wireless networks, it is common for a substantial break in connectivity to occur that would be unacceptable for streamed video. This paper proposes a scheme that ensures packets are not lost, through the use of soft handover. It is shown that the client can decide when to perform a soft handover by using the difference in packet delay between the two streams. The scheme is implemented and results are presented that show the successful handover of an RTP stream using this scheme in a test bed that emulates network conditions.

Analysis of Packet Loss and Latency Control for Robust IPTV over Mobile WiMAX and LTE Assessment (RESEARCH NOTE)
Abstract The streamed audio video (AV) content for IPTV across mobile WiMAX channel, the different schemes were discussed to reduce the noise, packet loss and latency. The objective of this paper is to verify the effectiveness of forward error correction (FEC) techniques and to suggest the techniques for robustness problems and to analysis the issues either due to AV coding encoding or due to...
متن کاملUsing cross-layer metrics to improve the performance of end-to-end handover mechanisms
Network centric handover solutions for all IP wireless networks usually require modifications to network infrastructure which can stifle any potential rollout. This has led researchers to begin looking at alternative approaches. Endpoint centric handover solutions do not require network infrastructure modification, thereby alleviating a large barrier to deployment. Current endpoint centric solu...
متن کاملSoft, Vertical Handover of Streamed Video
The delay and jitter of an RTP stream transported by TCP over WLAN are examined as candidates for assisting handover between networks. Jitter was found to be a good indicator of when a mobile is close to the edge of a WLAN cell and was used to spawn a vertical handover mechanism. The implemented handover scheme used an averaged delay difference to complete the handover of the video stream.
متن کاملQuality of Service and Security as Frameworks toward Next-Generation Wireless Networks
This article aims to analyze quality of service (QoS) and security as frameworks toward next-generation wireless networks. QoS, security and mobility can be viewed as three different indispensable aspects in 4G networks. However all are related to networks nodes involving the controlling or the processing if IP packets for end-to-end flows between a mobile node (MN) and its corresponding node (...
متن کاملOptimized handover and resource management: an 802.21-based scheme to optimize handover and resource management in hybrid satellite-terrestrial networks
Satellite communications can provide fourth generation (4G) networks with large-scale coverage. However, their integration to 4G is challenging because satellite networks have not been designed with handover in mind. The setup of satellite links takes time, and so, handovers must be anticipated long before. This paper proposes a generic scheme based on the Institute of Electrical and Electronic...
