In this paper, we propose CFMTC (Cascade Forest for Mobile Traces Classification), a mobile network trace-based traffic classification system, which exploits flow statistical features extracted from mobile traces. Compared to other classification approaches, our system is based upon the key insight that deep learning techniques and the statistical features of bidirectional flows of mobile traces can be combined together for accurate mobile application classification. In CFMTC, we first filter UDP and TCP flows from mobile traces according to the flow attributes (Source IP, Destination IP, Source port, Destination port, Protocol), and then train Cascade Forest to classify raw mobile traces. We use a feature selection method to find the optimal feature set and determine the influence of different features. Our approach involves the following key features: 1) suitable for mobile traces classification; 2) adapted Cascade Forest algorithm for mobile traffic classification; 3) applicable to both connection-oriented protocols and connection-less protocols; 4) effective for both encrypted and non-encrypted flows. We implement CFMTC and conduct extensive evaluations on mobile network traces containing text, audio and video flows generated by Kuwo Music, WeChat, PPTV Live traces. Our experimental results show that CFMTC has the ability to accurately classify the mobile traces of the target mobile applications with an average accuracy of about 88.71%. Our experimental results prove that CFMTC is a robust system, and meanwhile displays competitive performance in practice.","PeriodicalId":360054,"journal":{"name":"2018 IEEE Wireless Communications and Networking Conference (WCNC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115370745","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}

We analyze the wastage of transmission power for different types of placement of the APs with touching and intersecting circles for the full coverage of the rectangular region. We show that the minimum wastages in the inner bulk region with touching and intersecting circles are 81.4% and 20.77%, respectively. We then propose a systematic scheme to place the intersecting circles and show that for moderate size of the rectangle, the wastage due to the spill over of the circles at the boundary can be much higher that 20.77%, but when the side(s) of the rectangle is(are) very large compared to the radius r of the circles, the wastage asymptotically tends to around 20.86%. Also, we show that use of a few circles of smaller radius r' = 0.62r would significantly reduce the wastage even for a rectangle of small size and that would not require any additional bandwidth compared to the scheme for using all circles of the same radius r. The proposed placement scheme is very simple, elegant and effective in minimizing wastage of transmission power of APs as well as optimizing the bandwidth requirement through reuse of channels avoiding co-channel and adjacent channel interferences.","PeriodicalId":360054,"journal":{"name":"2018 IEEE Wireless Communications and Networking Conference (WCNC)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114573695","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}

Existing works concentrate only on the allocation of transmission resources (i.e., antenna time blocks) in time windows and may result in transmission conflicts hard to efficiently resolve, especially when multiple missions are activated simultaneously. To this end, we propose to further integrate computation with transmission resource allocation, to enable data compression so as to alleviate conflicts. Specifically, aiming to maximize the number of completed missions and minimize data loss, we first formulate the joint transmission and computation resource allocation problem as a mixed integer linear programming (MILP) one. Then, for the complexity reduction, we transform the MILP into an integer linear programming (ILP) one by fixing maximal data compression. Meanwhile, by constructing a conflict graph to characterize resource allocation conflicts, a time window scheduling algorithm is proposed to solve the ILP problem efficiently. Next, we further develop a data compression control algorithm to reduce data loss on the prerequisite of invariant mission number. Finally, simulation results show that the space network can benefit from the combination of transmission and computation resources in terms of both mission number and data loss.","PeriodicalId":360054,"journal":{"name":"2018 IEEE Wireless Communications and Networking Conference (WCNC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115014436","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}

Wake-up radio, a new technology being developed by IEEE, describes a broad solution to this challenge. In this paper, we address the issue of optimal sensor nodes selection to maximize the energy-efficiency of a WSN for IoT applications. A wake-up protocol is then applied on the optimally selected-sensor nodes. The node selection is formulated as an optimization problem with spatio-temporal correlation constraints thus minimizing redundant data transfer. Subsequently, a MLE method is used to solve the problem. Additional novelty of this work is the development of a wake-up protocol over hexagonal grids when a mobile sink is used for data aggregation leading to improved energy-efficiency. The impact of the proposed method on decision errors in IoT applications is also discussed. Extensive experiments are performed to analyse the energy-efficiency, estimation error, modelling accuracy, network lifetime of WSN in the context of IoT applications. Results indicate an improvement in energy-efficiency when compared to conventional methods.","PeriodicalId":360054,"journal":{"name":"2018 IEEE Wireless Communications and Networking Conference (WCNC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123662391","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}

The studies are based on simulations with 3GPP-specified radio channel models including path loss, shadowing and fast fading effects. The considered positioning approach exploits measurement of Time-Of-Arrival (TOA) and Angle-Of-Departure (AOD), which are estimated from beamformed NR synchronization signals. Based on the given measurements and the assumed train movement model, the train position is tracked by using an Extended Kalman Filter (EKF), which is able to handle the non-linear relationship between the TOA and AOD measurements, and the estimated train position parameters. It is shown that in the considered scenario the TOA measurements are able to achieve better accuracy compared to the AOD measurements. However, as shown by the results, the best tracking performance is achieved, when both of the measurements are considered. In this case, a very high, sub-meter, tracking accuracy can be achieved for most (>75%) of the tracking time, thus achieving the positioning accuracy requirements envisioned for the 5G NR. The pursued high-accuracy and high-availability positioning technology is considered to be in a key role in several envisioned HST use cases, such as mission-critical autonomous train systems.","PeriodicalId":360054,"journal":{"name":"2018 IEEE Wireless Communications and Networking Conference (WCNC)","volume":"439 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125762904","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}
