It is intended for remote control and sensor applications. ZigBee is designed to use low power digital radio signals for personal area networks which require secure networking. The use of the ZigBee protocol accommodates and facilitates for carrying out secure communications, ciphering frames and controlling devices, protecting establishment and transport of cryptographic keys. This paper presents a security enhancement technique for ZigBee by modifying the MAC layer. This work also serves enhanced security processing in Network and Application layer of ZigBee protocol. The improved security mechanism of Network and Application layer has been developed using Radio Frequency Identification (RFID) and proxy firewall techniques respectively. Riverbed v17.5 is used to simulate and scrutinize different ZigBee layers to enrich security. The result of this study provides reliable and stable ZigBee protocol scheme to end users. Furthermore, the paper shows security adoption in MAC, Network, and Application layers of ineligible nodes, packets, and data blocks. The benefits of the work include end-to-end security with confidentiality, data packet integrity, message and device authentication.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123553589","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}

Photovoltaic dark current, current-voltage responses at 15nm, 28nm, 59.5nm and 70nm thick Titanium Di-oxide layer indicate the ratio of power output from the solar cell to input power from the sun on thin silicon solar cell has been augmented by AR coating along with Indium nanoparticles. For bare silicon cell and Indium particle deposited, 59.5 nm thick spacer layer coated Si cell short circuit currents were 2.64mA and 3.81 mA respectively. The maximum short circuit current enhancement was observed as 44.32%while conversion efficiency was increased by 40.42% in comparison to simple silicon solar cell. The efficiency depends on the spectrum, the temperature and parasitic resistances of the solar cell. Therefore, conditions under which efficiency is measured must be sensibly controlled to evaluate the performance of the device. The temperature effect and non-ideality effect on cell performance was monitored.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122724145","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}

The analysis is carried out to find the expression of the signal current and multi access interference (MAI) current at the output of the SIK receiver considering the effect of atmospheric turbulence of the channel. The conditional BER conditioned on a given atmospheric turbulence is evaluated and the average BER is obtained by averaging the conditional BER over the probability density function (pdf) of atmospheric turbulence. The results are evaluated for different code length, number of simultaneous users, turbulence variances and other system parameters. The performance of an OCDMA link is found to be highly degraded due to atmospheric scintillation and the power penalty due to turbulence effect is of the order of 2 to 10 dB depending on the turbulence variance. For example, power penalty is 3 dB to 10 dB at a BER of 10-9 for 12 numbers of users at 1 Gbps corresponding to turbulence variance 0.01 to 0.3 respectively. However, the penalty can be reduced significantly by increasing the processing gain.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126990932","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}
