Since power harvested form such a system is a function of road roughness, vehicle speed, and the velocity of the vibrating suspension system of the vehicle, we assert that such system may not only be a source of scavenged electrical power, but also the basis of valuable data that can be used in several expedient ways. In this paper, we propose a system architecture that will collect and make use of this valuable data. According to the proposal, the system will deduce information from onboard energy scavenging system, index it with GPS coordinates, endorse it with timestamp, and make a portfolio of consolidated information. This information will then be dispensed to a dedicated server residing in a trusted third party network, where it will be accessed and used for several third party applications such as assessment of road roughness, evaluation of automobile's suspension system, and perceiving the driver behavior, etc. The proposed architecture consists of three key subsystems, named as Energy-scavenging and Data-acquisition Subsystem (EDS), Portfolio Dispatch Subsystem (PDS), and Storage and Analysis Subsystem (SAS). The holistic system presented in this paper is capable of offering plethora of value added services in cost effective way.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125764895","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}

One primary issue among researches is to verify the reliability of FlexRay systems either from protocol aspect or from system design aspect. However, for more precisely addressing the FlexRay system reliability issue, we require a more generic analysis that simultaneously considers the network topology, clock sync between FlexRay ECUs and the ECU fault-tolerance. To fulfill this requirement, in this paper we first apply a well-known reliability model, Dynamic Fault Tree (DFT), to model the reliability of FlexRay systems with various network topologies, and then employ the Markov Chain (MC) to model the reliability of clock sync in terms of the number of sync ECUs. Furthermore, various fault-tolerant techniques for ECUs protection are also modeled by MC. The adopted two reliability models, DFT and MC, are integrated to form a mixed DFT to assess the FlexRay system reliability more accurately. Through a FlexRay steer-by-wire case study, we demonstrate the influence of different topologies, different ECU fault-tolerance and various number of sync ECUs on the reliability of FlexRay steer-by-wire system.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131594164","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 leads to ambiguity about road conditions, which is tolerable during normal conditions but extremely problematic in adverse conditions such as snow blockages, water-logging due to storms, degraded roads and potholes. Without such knowledge, city authorities cannot take effective action against such problems. Also, one only has knowledge about ones immediate surroundings in a car, and not what to expect further down the road. Our approach is to deploy a number of embedded modules capable of sensing, computing and reporting, each of which can simply be plugged into any vehicle. Hence this enables each vehicle's connectivity to the cloud and larger coverage as compared to static sensors. The data reported by each module itself might be prone to errors. Therefore, the cloud crowd sources the data from these modules and merges it to increase confidence in the information. Our work, Panoptes, demonstrates these aspects through crowdsourced pothole detection for city roads.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"259 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123443427","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}

A multicell scenario with universal frequency reuse is considered, when the multicarrier signals are transmitted over frequency-selective Rayleigh fading channels. A decentralized multiuser detection (MUD) scheme, which combines the novel receiver multiuser diversity aided multi-stage minimum mean-square error MUD (RMD/MS-MMSE MUD) with the hard-decision data exchanged among the neighboring base-stations (BSs), is proposed and compared with the conventional MUD schemes without BS cooperation. Additionally, detection of several users per stage is considered in the RMD/MS-MMSE MUD to make a tradeoff among the complexity, performance and delay. The impacts of the number of users detected per stage, system load, intercell interference strength, and the spreading factors of both T-domain and F-domain spreading are explored. Our simulation results demonstrate that the proposed scheme significantly outperforms the conventional MUD schemes without BS cooperation, and may constitute a promising multicell processing (MCP) scheme.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128346488","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}

Our focus is on comparison of the achievable spectral-efficiency, when various base-station (BS) cooperation strategies and detection schemes are employed. Specifically, three BS operational schemes are considered, namely the ideal BS cooperation, data exchange only and no BS cooperation, in conjunction with four multiuser detection (MUD) schemes, including the optimum MUD (OMUD), OMUD with parallel interference cancellation (OMUD-PIC), linear minimum mean-square error MUD (MMSE-MUD) and the MMSE-based successive interference cancellation (MMSE-SIC). The impacts of system load, signal-to-noise ratio (SNR) and intercell interference strength on the achievable spectral-efficiency of the DS-CDMA and SDMA systems employing the above-mentioned BS cooperation and MUD schemes are investigated. Considering the trade-off between complexity and performance, our studies show that the MMSE-SIC aided by data exchange between BSs may constitute a promising multicell processing (MCP) scheme.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129948174","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}
