In this paper, we focus on the bitrate adaptation issue of HTTP live video streaming. We first present a systematic approach that enables the client to choose the best video quality when deciding video bitrate for next several segments. After that, based on the concept of JND (Just Noticeable Difference), an adaptation method is proposed to meet the tradeoff between the requirements of buffer stability...
This paper investigates the impact of the hop-count and node density on the network performance of mobile ad-hoc networks (MANETs). The analysis as well as simulation results indicate that the throughput decreases significantly when the packets traverse over a long chain of hops. Especially when the link is beyond 4 hops, the throughput can only get less than 60% of the single hop throughput. In another...
This paper introduces a Bayesian Classifier model to improve the performance for reactive routing protocols in mobile ad-hoc networks (MANETs). The model can help to increase the network throughput and reduce end-to-end delay by controlling the broadcast area. Additional information related to hop-counts and node densities are used to support routing protocol in broadcasting. It is shown that the...
