During a cell outage, users serviced by a base station disconnect from the network without warning because of a lack of signal coverage. Cell outages affect consumer interests and results in substantial losses for the telecommunications operator. In this study, cell outages in base stations are examined by constructing system models. Wireless interference and base station load were key considerations in the proposed outage users first cell outage compensation (OUF-COC) algorithm. The algorithm restores signal coverage and connections to users in the outage area without affecting users outside of the outage area. Simulations showed that OUF-COC could restore connections for over 90% of outage users. Approximately 50% of these users and 70% of users outside of the outage area experienced data rates of 250Kbps or higher (i.e., a typical data rate for a 3G network). These results indicated that the OUF-COC algorithm could effectively maintain quality of service among regular users while restoring connections to outage users and enhancing their data rates.","PeriodicalId":383937,"journal":{"name":"Proceedings of the International Conference on High Performance Compilation, Computing and Communications","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134339665","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 paper presents a RF energy harvester for ultra-low power semi-active UHF radio frequency identification tag applications. The main objective is to solve the semi-active UHF RFID tag limited lifespan issues due to the need for batteries to power its circuitries.In this design, the energy from the radiated RF signals is converted to electrical power by a module known as RF-DC rectifier. The circuit is based on a cross-connected differential-drive CMOS rectifier topology which is implemented in 0.13 μm CMOS standard technology with the input RF power range from -20 dBm to -10 dBm operating in 915 MHz frequency band. To ensure a maximum output voltage is achieved, several simulations based on the optimized matching network components, the variation of transistor sizes and load resistance, and increases the number of rectifier stages are investigated. All the circuit designs and simulations are performed using Orcad Cadance software. The simulated results shown that the optimized impedance matching network and a six-stage cross-connected differential-drive CMOS rectifier circuit able to produces a 1.13 V DC output voltage with an input power of -10 dBm (100 μW) and 1 MΩ load resistance.The results obtained shows that the proposed design can extend the lifetime of semi-active UHF RFID tag, able to eliminate its dependency on battery and make it possible to achieve a batteryless tag. Therefore, can be used to supply electrical power continuously for RFID tag applications.","PeriodicalId":383937,"journal":{"name":"Proceedings of the International Conference on High Performance Compilation, Computing and Communications","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125164542","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}

Yet it brings forth a new dimension of complexity in terms of many potential challenges specifically in areas of data security comprising data confidentiality and integrity aspects during data transfer phases in IoT. In order to promote secure data transfer in smart IoT environment, a security scheme is advocated in this paper which addresses both the aforesaid issues, employing a combined approach of lightweight Cryptography and Variable LSB Substitution Steganography technique. Further a comparative study is conducted between Simple LSB & Variable LSB Substitution algorithm where it can be concluded that the Variable LSB Substitution scheme offers better security than its Simple LSB Substitution counterpart.","PeriodicalId":383937,"journal":{"name":"Proceedings of the International Conference on High Performance Compilation, Computing and Communications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116475895","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}
