Networking of several CPSs, the internal networking of CPSs components as well as the interconnection with other systems, is of major importance with respect to scientific, engineering and technical considerations; yet, it is also very challenging. In this paper we describe an architecture and methods which can be used for various networked CPSs. To base the system design and approaches on realistic requirements and devise suitable methods, we use tightly cooperating, mobile robots as application area. This is an example of challenging CPSs which put high demands on the networking methods. Nevertheless, the considerations are applicable to other CPSs as well. In order to enable networked mobile robots to perform individual and cooperative tasks, real-time support and network operations such as merge, split, and synchronize among clusters of such robots are needed. Further, management functions have to be provided which enable independent, but concurrent clusters to allocate and share scarce network resources. In the context of this paper, network resources are considered in a broad sense (e.g., time slots, frequency channels, codes) and assigned by a novel scheduling algorithm. Thus, a schedule means not only a sequence of time slots, but it takes all mentioned dimensions into account.","PeriodicalId":285899,"journal":{"name":"2019 16th IEEE Annual Consumer Communications & Networking Conference (CCNC)","volume":"277 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134312646","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 paper studies these two important issues. First, we introduce a new model for content requests in stationary environments. The common approach to model the requests is through the Poisson stochastic process. However, the Poisson stochastic process is not a very flexible model since it cannot capture the correlations between contents. To resolve this limitation, we instead introduce the Poisson Factor Analysis (PFA) model for this purpose. In PFA, the correlations are modeled through additional random variables embedded in a low dimensional latent space. The correlations provide rich information about the underlying statistical properties of content requests which can be used for advanced cache-placement algorithms. Secondly, to learn the model, we use Bayesian Learning, an efficient framework which does not overfit. This is crucial in edge-caching systems since only partial view of the entire request set is available at the local cache and the learning method should be able to estimate the content popularities without overfitting. In the simulation results, we compare the performance of our approach with the existing popularity estimation method.","PeriodicalId":285899,"journal":{"name":"2019 16th IEEE Annual Consumer Communications & Networking Conference (CCNC)","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134525822","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}

However, packet collision caused by the hidden node problem becomes serious particularly in large-scale multi-hop WSNs. Moreover, focusing on periodic data flows, continuous packet collisions among periodic data flows are caused once periodic packet transmission phases are synchronized. In this paper, we tackle the compounded negative effect of the hidden node problem and the continuous collision problem among periodic data flows. To realize this objective, we propose a new MAC layer mechanism. The proposed method predicts risky durations during which collision can be caused by hidden nodes by taking into account periodic characteristics of data packet generation. In the risky duration, each sensor node stops the transmission of packets in order to avoid collisions. To the best of our knowledge, this is the first paper that considers the compounded effect of hidden nodes and continuous collisions among periodic data flows. Other advantages of the proposed method include that any new control packets are not required and it can be implemented in widelydiffused IEEE 802.11 and IEEE 802.15.4 devices.","PeriodicalId":285899,"journal":{"name":"2019 16th IEEE Annual Consumer Communications & Networking Conference (CCNC)","volume":"7 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115237144","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}

In IEEE 802.15.4 networks, sensors can also request GTSs for purpose of reliable communication. In existing GTS scheduling studies, however, a sensor wishing to use GTSs has to send a GTS request to a network coordinator. The sending of the GTS request by using carrier sense multiple access with collision avoidance (CSMA/CA) algorithm in fact creates more traffic in the networks. This results in more collisions and packets blocking probability. In addition, if the transmission of GTS request is failed, bandwidth utilization can be low because all GTSs are not allocated. This paper therefore proposes an advanced GTS scheduling (AGS) algorithm, applied in homogeneous networks, to solve those problems. The proposed algorithm eliminates the sending GTS request and allocates GTSs to sensors based on their time order of discovery and the observation of actual allocated GTS usage. Simulation results show that AGS algorithm improves the performance of IEEE 802.15.4 networks in term of bandwidth utilization, packet blocking probability and number of collision per transmission request. In some scenarios, packet blocking probability is reduced about 30 %.","PeriodicalId":285899,"journal":{"name":"2019 16th IEEE Annual Consumer Communications & Networking Conference (CCNC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114577389","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}

In this paper we study the joint design of high level dynamic video Quantization Parameter (QP) and the low level power control in QoE-driven downlink wireless multimedia services. Furthermore, we study QoE performance with new Non-Orthogonal Multiple Access (NOMA) schemes in the Base Station (BS) – UE multimedia downlink, and discuss the performance in comparison with conventional Orthogonal Multiple Access (OMA). We mathematically model UE’s QoE gain (also known as utility) by considering UE’s perceived data quality and the corresponding data cost. Then we show that there exists an optimal data consumption option for UE to achieve utility maximization based on different cost coefficients. In addition, the power allocation strategies and their associated constraints are investigated in both OMA and NOMA transmission schemes. Finally, through numerical simulations, we quantitatively analyze the impact of low level power allocation and high level QP control on UEs’ utility gain and the system throughput performance.","PeriodicalId":285899,"journal":{"name":"2019 16th IEEE Annual Consumer Communications & Networking Conference (CCNC)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123544234","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 current solution deployed by leading MNOs uses Dual IP 464XLAT to achieve address translation. There has been significant research on the dual IP system. However, an important area of study which is not investigated in detail is the correlation of 464XLAT in the multi-core architecture. We investigate the effects of this architecture on bandwidth utilization of mobile Smartphones with emphasis on multi-core scheduling algorithm. In this paper, we propose a novel networking packet scheduling scheme called CAA - CLAT Aware Affinity Scheduler for Next Generation Mobile Networks. CAA classifies the packets according to the characteristics and efficiently schedules among the CPU cores at its best effort for improved throughput in Dual Stack Smartphones. We also propose CAA-LITE, a lightweight version where the affinity scheduling is static with minimal steps. To illustrate the effectiveness of our proposed method, we conducted simulations in our lab at Samsung R&D India Bangalore and live air experiments in Samsung Electronics, South Korea. Our live air experiments show that the CAA outperforms the legacy by improving the throughput of around 90% under various operational conditions consistently. Moreover, our power consumption test shows that the CAA improves the power by 22% compared to original approaches.","PeriodicalId":285899,"journal":{"name":"2019 16th IEEE Annual Consumer Communications & Networking Conference (CCNC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125364413","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}
