“…The bottom X-axis tic marks represent the centre frequencies of the even numbered Wi-Fi channels, while the top X-axis tic marks show the channel numbers corresponding to those centre frequencies. Microwave Oven: Figure 3(a) shows that the microwave oven affects about half the available channels (6)(7)(8)(9)(10)(11)(12) in the 2.4 GHz band with the highest energy concentrated on channel 9. Note that the microwave oven is operating at high power levels of -80 to -60 dBm.…”

Abstract. This paper presents a measurement study of interference from six common devices that use the same 2.4 GHz ISM band as the IEEE 802.11 protocol. Using both controlled experiments and production environment measurements, we quantify the impact of these devices on the performance of 802.11 Wi-Fi networks. In our controlled experiments, we characterize the interference properties of these devices, as well as measure and discuss implications of interference on data, video, and voice traffic. Finally, we use measurements from a campus network to understand the impact of interference on the operational performance of the network. Overall, we find that the campus network is exposed to a large variety of non-Wi-Fi devices, and that these devices can have a significant impact on the interference level in the network.

“…The QoS information of the three sub-paths is shown in Table 3. As shown in Table 3, according to the sub-path QoS information obtained by monitoring, we used QoE as the evaluation standard to establish the judgment matrix of the QoS index by comparing the impact of different QoS indexes on the service transmission quality [30,31]:…”

Research on the Load Distribution Strategy to Meet the QoE Requirements for Conversational Real-Time HD Video Service

A reliable transmission with QoE (Quality of Experience) guarantee is crucial for internet conversational service applications. However, due to the limited network bandwidth bottleneck effect and the drawback of transmission technology, there exists no mature and open QoE technical solution for this service. In this paper, we focused our attention on a load distribution strategy for multipath relay transmission to meet the QoE requirements of conversational real-time HD video services. It consisted of three stages: First, a series of relay nodes was deployed in the backbone network, and a software defined overlay network was constructed to perform the multipath relay transmission for the service. Second, by an analysis of the QoE feature, a bijection was built for each quantitative QoE and its MOS (Mean Opinion Score) score. Finally, considering the influence of the coupling relation between paths on the service quality in multipath relay transmission, fuzzy cooperative game theory was used to design the service load distribution strategy. Many experiments showed that compared with state-of-the-art methods in the single-path transmission scene, the strategy we designed can dynamically adjust the load distribution of each sub-path according to the change in QoS (Quality of Service) information of the transmission path in real time. While meeting the strict real-time constraints of the service, it can effectively avoid the impact of network random congestion on the service QoE.

With the rapid development of video streaming era, multipath video streaming comes as a promising solution. However, dividing the video into different sub-streams is still considered as an important challenge for researchers. In this paper, we propose an approach for generating multiple complementary descriptions of the video flow, then to couple these descriptions with the path diversity provided by overlay video distribution networks (VDN). We select our overlay paths based on available bandwidth estimation. Furthermore, we use a hybrid assessment tool called PSQA for evaluating the quality of experience (QoE) over the recipient. Results show the automatic adaptability of our method with the load variation on different Internet paths. They also show the advantages of using Multiple Description Coding (MDC) video streaming, against the traditional multi-streams splitting strategies, especially in overloaded environments. Moreover, results show that MDC video streaming is more efficient in term of economizing on bandwidth over Internet paths.
