An Efficient Scheme for Video Delivery in Wireless Networks

Abstract

This chapter presents a theoretical background for the history of wireless networks. It gives a comprehensive overview and performance evaluation for IEEE 802.11, 802.15 and 802.16 standards focusing on different standards and coverage area. Then, this chapter proposes an efficient scheme for P2P VoD system based on a smart recommender taking into account the analysis of the user’s behavior. The chapter describes the proposed mobility scheme that describes network entry process and channel scanning process. The proposed models are examined using different video resolutions (low and high). Then, a mobility model is presented to study the influence of different scanning schemes (light and dense) on some performance metrics like throughput, data dropped, and particularly handover latency. Finally, simulation results are documented and analyzed. The simulation results show that the proposed scheme can efficiently improve both server’s load and the initial playout latency.
