Abstract

Nowadays Internet and bandwidth is an extremely valuable and scarce resource in remote networks. Consequently, efficient bandwidth management is necessary to support service stability, good Quality of service and ensure steady quality of experience for users of handheld multimedia streaming services. certainly, the support of uniform streaming rate during the entire course of a streaming videos, where the user is in mobility is one of the demanding issue and may not have high resolution or video quality due to the limited 3G/3.5G/4G bandwidth to the Internet as well as changing of bandwidth . Popular iOS and Android based handheld devices, accessing more Internet video services typically involves about 10%-80% redundant traffic and low battery life. This work proposes the Service transition protocol and Session transition protocol using H.264/SCV over the wireless network. This paper enables dynamic voltage and frequency Scaling Power control mechanism for better battery life. Simulation results shows that the proposed approach outperforms existing bandwidth management schemes in better supporting mobile multimedia services with better life time of battery.

Abstract

Background/Objective: The main objective of this work is to reduce the load balancing problems and problems like frozen play in the HTTP live streaming. Methods/Statistical Analysis: Cloud based http live streaming system used in the previous researches provides improved client satisfaction level but the main issue is the load balancing where the multiple clients' requests need to be processed in the single HLS server. The burden of HLS server would be increased in case of presence of multiple user requests. To overcome this problem multi server based HTTP live streaming approach is proposed. Findings: The multiple clients' requests would be handled by providing the appropriate services to them based on PSO approach which is used to calculate the weight function. An efficient particle swarm optimization is used for access the multimedia content from appropriate severs when client send the request to multiple servers. The multi-server concept can eliminate the high load variation problem by changing the load request based on user requirements dynamically. Applications/Improvements: Experimental results prove that the proposed methodology provides better result than the existing approach in terms bandwidth utilization and Peak signal-to-noise ratio.

Abstract

Telemedicine is one of the effective applications of the technological advancements coupled with the developments in the field of medicine and plays a vital role in today's world. A survey has been conducted on various types of coding techniques, video compression standards for real-time transmission of video over wireless network and also on the cross layer design framework which makes the telemedicine not only possible but efficient. In this paper we address and analyze the relevant challenges of cross layer design for real time rate adaptation of video streaming with reference to the various video coding techniques. A comparative performance analysis of such approach is validated and the advantages are analyzed. This survey is conducted in order to improve the performance of telemedicine considering the bandwidth constraints and quality of service. We review the existing Cross Layer Design (CLD) approaches and provide the solution to use the appropriate layers for CLD framework from the stack protocol.
