Recently, there is an increase interest in positioning techniques based on Global Navigation Satellite Systems so we focus on the performance evaluation of a positioning algorithm. The current method of solving for GPS user's position is to linearize the pseudorange equations and calculate the user position iteratively, starting with a user provided initial position guess. We implement an Iterative Least Squares (ILS) algorithm by means of data structures and show that five iterations are required to obtain a convergent solution. The algorithm automatically combines all available GPS pseudorange measurements when more than four satellites are observed. Experimental results show that reliable absolute positioning is achieved by using the algorithm. By weighting each satellite's contribution in user position evaluation process by means of Carrier-to-noise-density ratio (C/No) is achieved an improvement on the position estimation mostly in the vertical component.","PeriodicalId":227978,"journal":{"name":"2013 Eighth International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130567854","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}

Chu","doi":"10.1109/BWCCA.2013.70","DOIUrl":"https://doi.org/10.1109/BWCCA.2013.70","url":null,"abstract":"With the rising popularity of mobile devices, the requirements of accessing wireless networks through mobile devices have been significantly higher than before. Many researches try their best to develop different communication functions and services to serve users. On the other hand, up to present from 2008 Long Term Evolution (LTE for short) has still stayed in its spotlight. Also, the population of mobile users increases significantly in recent years. When a user equipment (UE for short) moves from an evolved Node B (eNB for short) to another, the LTE needs to perform handover to help the serving and target eNBs to manage the provided resources so as to maintain the connections connecting the UE and the eNBs. If handover incompletely performed, users will experience a longer transmission delay, or even the connections are disconnected. Currently, the factor that affects the time consumed by the handover procedure is still considered as the radio issue. However, it is insufficient if we only measure the strength of the radio that the UE receives from its serving eNB to determine whether UE needs to hand over or not since the UE's location, moving speed and moving direction are also the important factors that may affect the handover quality. In this study, we employs a GPS system to help the determination of handover of the LTE system so as to more accurately choose the most suitable target eNB and improve the performance of handover.","PeriodicalId":227978,"journal":{"name":"2013 Eighth International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133509942","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}

Unfortunately, most of closed-network SCADA systems have been considered as very secure against cyber-attacks. Because they use their own operating systems and communication/ network protocols, and their private networks are physically isolated from the public networks and the Internet. However, in case the closed SCADA system has m-connected status due to its maintenance, updates, and patches, it is no longer perfectly secure against cyber-attacks. This paper analyzes vulnerabilities of m-connected SCADA networks and proposes a novel security model for detecting network anomalies. The proposed model is based on an intrusion detection system using the network-based pattern reference method, which has two kinds of rule sets - one is the base rule set, and the other is dynamically produced rule set. The basic rule set can be set with pre-known intrusion patterns, and a dynamically produced new rule set can be set by detecting network anomalies under specific threshold values. Such new rule set would be adapted to the pattern reference model in its next execution time. Therefore, the proposed security model can identify abnormal command execution more effectively and efficiently.","PeriodicalId":227978,"journal":{"name":"2013 Eighth International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"12 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114000765","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}
