In order to overcome this limitation, Bluetooth technology can be employed. Furthermore, Bluetooth technology provides an accurate and low cost solution for short range wireless communication. Most of the digital devices provide the Bluetooth functionality which also makes it a good candidate for indoor positioning. In this paper, we use Bluetooth devices for indoor positioning and use signal based parameters such as received power level for position estimation. The accuracy of indoor positioning system is greatly dependant on the parameters selected for estimation and the measurements obtained from the environment. However, the measurements are corrupted by various environmental conditions such as temperature, reflection, presence of obstacles, human body and other communication signals. Therefore, we need to filter the measurements. This paper presents an experimental relationship between the received power level and distance using the standard radio propagation model. The idea behind this study is to provide an accurate distance estimate for Trilateration approach. Based on the experiments performed, the average error is minimized from 5.87 meters to 2.67 meters using gradient filter. The use of gradient filter improves the accuracy by 45 %.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132410029","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, it is difficult for users to retrieve relevant teaching material in cloud environments by submitting a few keywords. We propose a search mechanism based on social networks. Furthermore, the issues of availability and trustworthiness have to be considered in teaching material retrieval process, in order to improve the retrieval performance. Current P2P file sharing applications focus on exact matching and ignore the dynamic nature inherent in P2P networks, which might degrade the retrieval performance in terms of precision and response time. Our idea is to appropriately set the due time to improve response time of P2P teaching material retrieval without sacrificing much precision. In this study, we formulate the due time setting problem as a bi-objective optimization problem and approximately solve it by an interaction-based heuristic method. The proposed approach consists of two phases: construction phase and sharing phase. In construction phase, peer information is acquired and managed in a decentralized manner. In sharing phase, the due time is interactively determined and the results are retrieved. A prototype of cloud platform has been constructed and experiments have been conducted to evaluate the performance of the approach. The experimental results show that the interactive algorithm performs well in P2P networks with low trust and availability. Also, a survey of satisfaction shows that the proposed method is more user-friendly.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124610687","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}

To move to high-speed serial from Parallel bus architectures has become prevalent and among these Ethernet is the most preferred switched Serial bus, which is forward-looking and backward-compatible. Great stride have been made in promoting Ethernet use for industrial networks and factory automation. The Web based distributed measurement and control is slowly replacing parallel architectures due to its non-crate architecture which reduces complexities of cooling, maintenance etc. for slow speed field processing. A new kind of expandable, distributed large I/O data acquisition system based on low cost microcontroller based web server[1] boards has been investigated and developed in this paper, whose hardware boards use 8-bit RISC processor with Ethernet controller, and software platform use AVR-GCC for firmware and Python for OS independent man machine interface. This system can measure all kinds of electrical and thermal parameters such as voltage, current, thermocouple, RTD, and so on. The measured data can be displayed on web pages at different geographical locations, and at the same time can be transmitted through RJ-45 Ethernet network to remote web based data acquisition and control (DAC) monitoring system by using HTTP protocol. A central embedded single board can act as a central CPU to communicate between web servers automatically. The novelty of this proposed system is a substitute of web PLC for industry application.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121564545","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, this approach may cause a serious contention in transmission between adjacent nodes and a considerable amount of control packets. In addition, most of ad hoc routing protocols establish the route with minimum hop count. Consequently, the performance of ad hoc routing protocol is considerably affected by link (or route) duration since the network comprises the nodes with unrestricted mobility and constrained range in transmission. This paper proposes a novel routing algorithm that aims to i) minimize routing overhead in route discovery procedure, and ii) guarantee a reliable and fast packet delivery between source and destination, especially in providing real-time applications over MANETs. To achieve this objective, we introduce Relay Region within the transmission range of nodes in order to select optimal next relaying nodes for supporting specific application requirements in route discovery procedure. The proposed Relay Region is defined by the limited distance progress in transmission to next relaying node in order to maintain the established route for an arbitrary length of time (i.e., route duration) while meeting packet delivery reliability and delay constraints. The simulation results showed that the proposed scheme can significantly improve the performance of packet delivery ratio and packet delivery latency, reducing transmission redundancy in route discovery procedure.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"52 Pt 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128953319","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}
