Due to the poor scalability of DRAM, the performance of big data analysis and related applications is difficult to improve. DRAM/NVM hybrid storage architecture has the advantages of non-volatile and high storage density, which brings an opportunity to optimize big data analysis. Because the task itself depends on the data and does not modify the data, it is possible to solve the problem of operation delay if the data is deployed well on the storage system under the background of hybrid storage architecture. In order to optimize the problem of high latency, this paper discusses the data migration between disk and NVM and proposes a data deployment algorithm based on data label. The validity of labeling is verified by calculating the total time of reading data by tasks in the experiment and the efficiency of task execution is improved.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123929956","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}

Since the capacity of a single BS is constrained, only a small number of service can be executed simultaneously by each BS. However, when the BSs are densely deployed in the network, the BSs that are close to each other can cooperatively cache the services to improve the performance of the system. Moreover, we should avoid frequent service switching when the users' service requests always change. In this paper, we study the dynamic service caching (DSC) problem in mobile edge networks. Our objective is to minimize the traffic load that needs to be forwarded to the cloud, as well as considering service switching cost of BSs. This DSC problem involves two important issues, which include cooperative service caching of adjacent BSs and service switching in adjacent time slots. To solve the DSC problem, we propose a dynamic service caching algorithm for the BSs to cooperatively cache the services in an online manner. The simulation results show that our algorithm can greatly reduce the forwarded traffic load without frequently changing the service caching of BSs.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124476226","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}

Security detection before system installation is not enough to ensure that IoT devices are always secure, because newly emerging vulnerabilities can still be exploited to launch attacks. To address this issue, retrospective detection is often required to trace the security status of IoT systems. Unfortunately, existing centralized detection mechanisms cannot easily provide a comprehensive security analysis. In particular, consumers cannot automatically receive security notification whenever a new vulnerability is uncovered. In this paper, we propose a novel blockchain-powered incentive platform, called SmartRetro, that can incentivize and attract more distributed detectors to participate in retrospective vulnerability detection and contribute their detection results. Leveraging smart contracts, consumers in SmartRetro receive automatic security feedback about their installed IoT systems. We perform the security and theoretical analysis to demonstrate that SmartRetro achieves our desirable security goals.We further implement SmartRetro prototype on Ethereum to evaluate its performance. Our experimental results show SmartRetro is technically feasible and economically beneficial.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"555 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121130284","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, VLC is only suitable for downlink data transmissions from LED illumination infrastructures to mobile users. Moreover, due to the line-of-sight (LOS) transmission feature of visible light, the VLC downlink can be easily interrupted by blockage of obstacles or rotation of receivers, which leads to unreliable coverage of mobile users. To overcome the above two drawbacks of VLC, an integrated VLC and WiFi system is designed in this paper. In our proposed system, a 2.5 sublayer called link convergence (LC) layer between the IP layer and the data link layer is designed to integrate WiFi radio and VLC radio. The following key mechanisms are designed in the LC layer to support efficient communications of the integrated system: (a) VLC radio access; (b) VLC ARP table; (c) VLC selective ARQ; (d) VLC link maintenance; (e) handover between WiFi and VLC. Since the integration is above date link layer, no MAC driver or protocol modifications are needed for WiFi in our system. A prototype of our designed integrated system is implemented. Experiment results validate the feasibility and effectiveness of our proposed system.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"76 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116564330","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}

Given the GPS infeasibility for a lane-level accuracy, inLaneCom utilizes smartphone's inertial sensors to generate a unique lane signature used as lane ID in the exchanged messages. Lane signature consists of combined features extracted from phone's inertial sensors. Two main features types were exploited: physical features and traffic features. Physical features capture the characteristics of the lane surface such as bumps, potholes, and energy. Traffic features capture traffic characteristics such as speed, number of stops, waiting time per stop, acceleration, and deceleration. inLaneCom was evaluated under various road conditions, on highways and urban roads, using different types of vehicles. To the best of our knowledge, inLaneCom is the first framework to enable communication between vehicles on the same lane. This framework would enable several safety and navigation applications that require data exchange between vehicles on the same lane.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115964222","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}

At present, one of the problems that the technology needs to solve is that the recognition speed needs to be improved. The fast determinant recursion method is originally used for adaptive and fast processing of radar signals. In this paper, FDR (Fast Determinant Recursion) is used to speed up identifying characters. The advantage of this method is that it does not need to construct the estimation of the covariance matrix of the sample, and does not need to inverse the matrix. In the case of ensuring the constant accuracy of the recognition, the algorithm can improve the recognition speed of the characters.

One critical challenge of today's VANET is how to provide high quality network services with lower packet loss rate and delay in the scenario of frequent movement and handover. Previous work most either focused the mobile management on selecting a fixed point or dynamically select different forwarding points. Unfortunately, most of these solutions cause triangle routing problems or generate a lot of signaling overhead. They overlooked the balance of dynamic routing and signaling overhead. In this paper, we propose a scheme that uses a dynamic repeat point selection algorithm in the VANET architecture, reusing part of the switch's flow tables as much as possible to save signaling cost and reducing handover delay. Extensive experimental results show that this scheme saves signaling overhead during handover, reduces handover delay and the loss rate of data packets.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134211411","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}

It allows users to exchange large chunks of data without relying on stationary network infrastructures. This paper proposes a scalability and privacy preserving routing algorithm. The core of a multi-hop routing scheme is the prediction of the next relay router, which ideally is the next hop on the shortest path to the destination of the message. The proposed routing algorithm contains a machine learning based prediction model that is trained on a trace of nodes connection events collected during a warm up period in a network where the mobility is assumed to exhibit a certain degree of regularity as in general human social networks. The algorithm is scalable since the prediction model, i.e. the control plane of the algorithm, only needs to maintain and broadcast the trained model that implicitly encodes the possible mobility locations and patterns within the mobility area, which is a constant to the number of nodes in the network. The algorithm is privacy preserving because that it does not require the nodes to disclose to other nodes any explicit information about its previous mobility or its personal preferences. Privacy preserving is achieved by using distributed node representations that jointly encode the mobility pattern of the node together with the prediction model, instead of using explicit statistical information to represent previous connectivity patterns as in prior work. This on one hand make attacker hard to find out any exact information about any particular node, and on the other hand enables the routing algorithm to extrapolate to the prediction of nodes of unseen mobility pattern, which is difficult if hand designed statistical mobility information is used. To perform large scale experiments, we collect very large synthetic mobility trace from university course registration information, this trace contain a total of about 35,000 nodes and 300 million message forwarding links. Experiments are conduct to examine several prediction accuracies of our algorithm.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"32 22","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132938585","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 focuses on a robust state prediction problem in collaborative sensing where the goal is to provide an accurate prediction on the dynamic status of the physical environment (e.g., air quality index, temperature, traffic) based on the incomplete and noisy data contributed by collaborative sensors. While significant progress has been made to study the state prediction problem, we identify two fundamental challenges that have not been well addressed by the current literature. The first challenge is \"latent spatial dynamics\": the spatial correlations among measured variables are highly dynamic and the features that affect such dynamics may not be directly observable from the sensing data. The second challenge is \"incomplete and noisy data\": a significant amount of measurements are missing in collaborative sensing due to the prohibitively high cost of deploying sensors for full spatial-temporal coverage. The collaborative sensors are also known to be unreliable in many applications and can easily contribute to noisy measurements. To address these challenges, this paper develops a Context-Aware Collaborative Sensing Prediction (CACSP) scheme inspired by techniques from latent semantic analysis and statistics. We evaluate our scheme through two real-world collaborative sensing applications and the results show that CACSP significantly outperforms the state-of-the-art baselines.","PeriodicalId":146214,"journal":{"name":"2018 IEEE 15th International Conference on Mobile Ad Hoc and Sensor Systems (MASS)","volume":"542 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116254253","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}
