Therefore, this paper proposes GPS Anti-spoofing Algorithm Based on Improved Particle Filter. By the introduction of positioning error correction and M-estimation theory, simulation results and analyses verify that proposed algorithm achieves the purpose of eliminating spoofing jamming by modifying pseudo range error.","PeriodicalId":203781,"journal":{"name":"2018 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115570375","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}

Sensor networks consist of limited battery-powered nodes and recharging or replacing is not practical being deployed in harsh environments like underground mines. So designing of WSNs should be concentrated on energy efficiency. Clustering technique is used very effectively to achieve scaling up and power saving in WSNs. It allows hierarchical structures to be built on the nodes and enables the more efficient use of scares resources. In this work, we have proposed a hybrid clustering scheme which able to meet energy constraints of WSNs. It allows data transmission from sensor nodes to the sink with reasonable consumption of energy.","PeriodicalId":203781,"journal":{"name":"2018 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114211382","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}

Blister refers to LDPE-Aluminum composite prevalently employed as high grade package material in food and pharmaceutical industry, whose disposal has significant negative environmental impact. Blister pack particles employed as package materials for tablets and capsules in pharmaceutical industry is proposed as the conductive filler. Cement mortar formed with Ordinary Portland Cement (OPC), sand and water forms the base. Blister composition attempted was 6.5% with a particle aspect ratio less than 1mm, Shielding Effectiveness measurements as per ASTM 4935 two antenna standard, in J band is determined. Enhanced shielding effectiveness around 6dB is observed. No degradation in mechanical strength unlike the conventional mortar. The proposed filler provides dual purpose: the aluminum provides the EMI shielding, and the LDPE component provides mechanical strength. Further research on determining composition levels for achieving specified SE level, automating blister machining process and expanding the frequency range of analysis is underway. This paper aims to propose a Cement-Blister composite at a low cost, field deployable EMI mitigation scheme at structural level.","PeriodicalId":203781,"journal":{"name":"2018 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115163452","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}
