New low- power wide area (LPWA) wireless network technologies have been proposed to support this large number of asynchronous, low-bandwidth devices. Among them, the Cooperative UltraNarrowband (C-UNB) is a clean-slate cellular network technology to connect these devices to a remote site or data collection server. C-UNB employs small bandwidth channels, and a lightweight random access protocol. In this paper, a new application is investigated - the use of C-UNB wireless networks to support the Advanced Metering Infrastructure (AMI), in order to facilitate the communication between smart meters and utilities. To this end, we adapted a mathematical model for C-UNB, and implemented a network simulation module in NS-3 to represent C-UNB's physical and medium access control layer. For the application layer, we implemented the DLMS-COSEM protocol, or Device Language Message Specification - Companion Specification for Energy Metering. Details of the simulation module are presented and we conclude that it supports the results of the mathematical model.","PeriodicalId":101731,"journal":{"name":"2019 IEEE ComSoc International Communications Quality and Reliability Workshop (CQR)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115661544","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}

Smartphones can run a wide variety of applications, each generating distinctive traffic. From the perspective of network operation, classification of these types of traffic in order to prioritize quality-sensitive traffic over best-effort traffic has the potential to improve network performance. Network operators generally treat web browsing, Voice over Internet Protocol (VoIP), video streaming, and other interactive traffic as quality-sensitive traffic. This quality-sensitive traffic is generally generated by user interactions on the current foreground application, hence its communication quality is likely to affect user’s quality of experience (QoE) directly. On the other hand, traffic generated when the smartphone is inactive has a low potential for affecting user’s QoE. As a traffic classification technique, machine learning is popular and demonstrates high accuracy; however, it is disadvantageous in that it involves gathering enough training data sets for supervised training. We propose a framework for online smartphone traffic classification that classifies traffic according to whether it is generated when the smartphone is active or inactive. A key feature of the proposed framework is automation of training data collection for machine learning. An application on the smartphone periodically estimates whether that smartphone is active or not, then it uploads the estimation results with timestamps as a source of training data sets. We also implemented a prototype of the proposed framework and assessed the feasibility of the proposal.","PeriodicalId":101731,"journal":{"name":"2019 IEEE ComSoc International Communications Quality and Reliability Workshop (CQR)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130185208","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}

Moore, Peixiang Liu","doi":"10.1109/CQR.2019.8880073","DOIUrl":"https://doi.org/10.1109/CQR.2019.8880073","url":null,"abstract":"Clustering serves a vital role in the operation of Vehicular Ad hoc Networks (VANETs) by continually grouping highly mobile vehicles into logical hierarchical structures. These moving clusters help stabilize a global topology for message routing, and enable multi-channel operations: utilizing a long- range control channel for control data, and a short-range service channel for intra-cluster communications. Clustering techniques are partitioned in research into two categories: active and passive. Active techniques rely on periodic beacon messages from all vehicles containing location, velocity, and direction information. However, in areas of high vehicle density, congestion may occur on the long-range channel used for beacon messages limiting the scale of the VANET. Passive techniques use embedded information in the packet headers of existing traffic to handle clustering. In passive clustering, vehicles not transmitting traffic may cause cluster heads to contain stale and malformed clusters. This paper proposes a hybrid (active-passive) clustering technique, where the passive technique is used as a congestion control strategy when congestion is detected in the network. In this case, cluster members halt their periodic beacon messages on the control channel and embed position information in the packet header of traffic over the service channel to update the cluster head of their position. This multi-channel technique dynamically reduces the channel load of the control channel in urban VANET scenarios, increasing the scalability of the VANET. Simulation results show that the hybrid technique is effective at controlling congestion and reducing message delay in an urban VANET environment when compared to active clustering techniques.","PeriodicalId":101731,"journal":{"name":"2019 IEEE ComSoc International Communications Quality and Reliability Workshop (CQR)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121271426","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}
