The IEEE 1609.4 MAC is designed for VANETs to support multi-channel operations, but it is neither reliable enough for the safety message broadcast nor efficient enough in the service channel (SCH) resources utilization. In this paper, we propose a Cooperative - Efficient - Reliable multi-channel MAC for VANETs, named CER-MAC, which supports both TDMA and CSMA schemes in accessing the control channel (CCH) and provides cooperation in broadcasting the safety messages. The CER-MAC allows vehicle nodes to send safety messages without collision on the CCH within their reserved time slots or the time slots permitted by the neighbors. Moreover, the CER-MAC utilizes the SCH resources during the control channel interval (CCHI) for the non-safety message transmissions. Compared to the current IEEE 1609.4, the proposed CER-MAC protocol outperforms in the reliability for the safety message broadcast and the efficiency for the service channel utilization.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127191739","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}

Firstly, a voltage bandgap is designed using only MOSFET instead of BJT in conventional architecture to reduce significantly the chip size. Secondly, to increase the stability of LDO we proposed a controlled circuit to vary output resistance according to output-load current. The latter technique also allows removing the feedback capacitor normally used in a conventional LDO architecture. The proposed LDO has a stable output voltage at 1.8V with input voltage varying from 2.1V to 3.3 V, a maximum current of 10 mA, and only 0.0058 mm2 chip area.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132148059","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}

Hence, introduction of failure detection and recovery is mandatory. Until now, various failure detection and recovery methods such as route switch and multiple routes detection have been proposed based on an assumption with stop failure model. However, the assumption that failed wireless nodes never transmit any messages too restricts the area where the proposed methods can be applied. In order to solve this problem, we propose a novel failure detection and notification method that supports not only stop failure but also Byzantine failure. That is, it is possible for failed wireless nodes to transmit malicious messages not according to the data message transmission and the failure detection and notification protocols unconsciously due to failure or even intentionally. Here, the design of failure detection and notification protocols is critical. In this paper, Byzantine failures in an intermediate node are detected by its multiple neighbor wireless nodes cooperatively since the neighbor wireless nodes are also vulnerable and might transmit erroneous failure notifications. From the performance viewpoint, no additional control messages are required to be transmitted while no failure wireless node is detected, i.e., in usual data message transmissions.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122859179","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 approach based on the Verdu's theorem [2], the concept of the spatial constellation (SC) codewords and maximum likelihood (ML) decoder in [1] results in the new upper bound which is tighter than the union bound due to eliminating a number of redundant pairwise error probabilities (PEPs). Therefore, by using the new upper bound rather than the union bound, we can evaluate the bit-error performance of HR-SM systems more exactly, especially when the signal-to-noise power ratio (SNR) is sufficiently high.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133918686","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 system can be used to link farmers and agricultural experts, thus, it can be considered as an online “farmer-expert bridge”. To build the system, at first, we need to build modules for sending and receiving SMS/MMS messages. These modules are important for farmers to send questions or images, e.g., about their rice status, that need to be consulted by the agricultural experts. Next, a message classification module is built using a combination of machine learning method (e.g., SVM) with image and text processing technologies. Finally, a whole web-based system is conducted to integrate these modules. Initial results show that construction of this system is feasible. This is also the foundation for building an online automatic agricultural extension support system through mobile communication networks.","PeriodicalId":142783,"journal":{"name":"2015 International Conference on Advanced Technologies for Communications (ATC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116113904","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}

Also, four other techniques, namely Mean Background, Gaussian Mixture Model, Mean Shift Tracking and Particle Filter are also investigated. In this study, we use the self-built database with some typical tracking situations such as appearance of illusions, different swimming velocities of the fish and qualities of water. Mean square error and Variance are used to assess the performance of each technique for different scenarios.
