However, the backhaul of these deployments will face several challenges where point-to-point (PTP) and point-to-multipoint (PMP) wireless technologies will be combined forming multipoint-to-multipoint (MP2MP) wireless mesh backhauls. In this context, routing and load balancing solutions will be of key importance to maximize the use of wireless backhaul resources. This paper presents Backpressure for Multi-Radio (BP-MR), a distributed routing and load balancing protocol specifically designed for heterogeneous MP2MP wireless mesh backhauls. The backhaul is heterogeneous in the sense that each node may embed a different number of diverse wireless interfaces. BP-MR introduces a two-stage routing process to appropriately handle Head-of-Line blocking issues that appear in such multi-radio environments. We validate these improvements with ns-3 simulations under different network conditions. As a consequence of an improved wireless link usage efficiency, results show improvements in throughput of up to 34% and in latency of up to one order of magnitude with respect to state-of-the-art approaches.","PeriodicalId":240086,"journal":{"name":"2015 8th IFIP Wireless and Mobile Networking Conference (WMNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129020653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimizing Quality of Experience - smooth, quick, and high quality playback - is more difficult in this setting, due to the highly dynamic nature of wireless links. A key requirement for achieving this goal is estimating the available bandwidth of mobile devices. Ideally, this should be done quickly and with low overhead. One challenge is that the majority of connections on mobiles are short-lived TCP connections, where a significant portion of data exchange is within the slow start phase. In this paper, we propose a novel method that passively estimates the currently available bandwidth by monitoring the minimal traffic generated by such connections. To the best of our knowledge, no other solution can operate with such constrained input. Our estimation method is able to achieve good precision despite artifacts introduced by the slow start behavior of TCP, mobile scheduler and phone hardware. We evaluate our solution against traces collected in 4 European countries. Furthermore, the small footprint of our algorithm allows its deployment on resource limited devices.","PeriodicalId":240086,"journal":{"name":"2015 8th IFIP Wireless and Mobile Networking Conference (WMNC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116585823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Video is one of the most demanding services in terms of network efficiency, reliability, and quality. In this work, we present a comparative performance evaluation of three different video streaming protocols, namely MPEG-DASH, RTSP, and RTMP for both on-demand and live video streaming over 4G and Wi-Fi (under different network conditions) in terms of Quality of user Experience (QoE). QoE measurements have been done (i) applying the recently standardized ITU-T Rec P-1201.1, which specifies the model algorithm for non-intrusive monitoring of video quality of IP-based video services based on packet header information for the lower resolution application area, and (ii) an extended non-standardized parametric model for comparative purposes. Results suggest that RTSP is more efficient than MPEG DASH for starting the video playback, but at the expense of decreasing QoE due to packet losses. We have also detected that PLR has a bigger influence over re-buffering events than end-to-end delay both in 4G/LTE and Wi-Fi, and that a slightly best quality is achieved by using QPSK at 20 MHz in 4G/LTE. QoE is noticeably higher with MPEG DASH than that attained by using RTSP, but slightly worse than that obtained with RTMP. Finally, our findings suggest that the use of parametric models for video QoE evaluation should be carefully review in terms of the weight that packet losses should have when streaming protocols based on reliable transport protocols (e.g., TCP) are used.","PeriodicalId":240086,"journal":{"name":"2015 8th IFIP Wireless and Mobile Networking Conference (WMNC)","volume":"26 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123454289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true in critical-time applications, where ensuring an adequate report latency allows a proper reaction from the network to the occurring phenomena. Despite a QoS analysis based on mean report latency is clearly insufficient for critical-time applications, it is oftentimes presented as the main performance indicator. For instance, high percentiles or the whole distribution of the report latency are much better suited. Furthermore, several applications, such as target positioning, require the transmission of a certain number of event packets to accurately characterize occurring events. Building on this, we present a hybrid method for obtaining the report latency distribution of random access (RA) WSN protocols. Here, the distribution of detecting nodes is obtained by simulation and then we perform the mathematical analysis of QoS parameters. Since the proposed method comprises a general structure, it can be easily adapted for analyzing the QoS of a wide range of RA WSN protocols. We use this method for evaluating the report latency, along with the energy consumption of RA protocols in applications that require the transmission of, at least, k event messages. Results show that the combination of higher detection ranges with low congested wireless environments leads to a clear reduction in report latency and event overlooking probability. This leads to an overall performance increase.","PeriodicalId":240086,"journal":{"name":"2015 8th IFIP Wireless and Mobile Networking Conference (WMNC)","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122317235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
