Abstract

Out of total mobile data traffic, mobile video traffic accounts for 55%. Massive increase in mobile video traffic trend and simultaneous proliferation in smart devices strains the expanding cellular network that triggers the demand to retain the quality of video. To fortify this challenge, proximity-based video delivery architectures are put forward. Four novel architectures are proposed depending on the location of the users, which tends to reduce load on video servers and core network elements. Through realistic simulation results, it is proved that the present system procures up to 69.15% increase in throughput, 40.81% decrease in end-to-end delay and 92% reduction in jitter as compared with the traditional 4G long term evolution (LTE)/LTE-A system. The proposed video dispatching architecture outperforms the existing strategy by 53% and increases the cell capacity up to four times compared with the current 4G LTE/LTE-A networks.
