OFDM has many advantages over other modulation techniques such as a high resistance to inter-symbol interference (ISI) and it is robust against fading caused by multipath propagation. Optical fiber cable (OFC) as a transmission media is used for distortion less transmission of data at a very higher data speed. OFC cable has a lot of advantages over other media. And OFDM over OFC cable will provide data speeds at a very high speed and with very less losses. In this work optical transmitter and receiver for OFDM based optical network has designed for high speed data transmission over optical fiber. While modeling the system we have also used post, pre and symmetric compensation technique to reconfigure the bandwidth along with add drop multiplexer, tunable filters and optical amplifiers to achieve high performance with minimum distortion and low bit error rate (BER).","PeriodicalId":101532,"journal":{"name":"2014 International Conference on Advances in Communication and Computing Technologies (ICACACT 2014)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126318754","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}

Recently the emergence of intelligent, sophisticated attacks like DOS (Denial of Service) makes web services more vulnerable than ever. To handle the DOS attacks, CAPTCHAs are used as one of the standard security technology. CAPTCHAs generate grade tests that most humans can pass but current computer programs can't. Human users and automated scripts can be classified and CAPTCHA is one of the possible ways to classify them. Text based CAPTCHAs are used in many applications but they face a challenge due to language dependency. Dynamic image based CAPTCHAs can strength the robustness of CAPTCHAs. It improves the human success rate. The probability of a BOT hacking the system is considerably low as compared to existing text based CAPTCHA. In this paper, an image-based Avatar CAPTCHA for mobile devices has been proposed as a potential solution. The solution of CAPTCHA is that users must correctly identify visually distorted human faces embedded in a complex background without selecting any non-human Avatar face. With this proposed work, CAPTCHA service is hosted on cloud that will generate CAPTCHA on cloud, so it improves efficiency of CAPTCHA generation also reduces response time for the use to authenticate as human. The need for usability and presentation that is required for a mobile device is considered during implementation. The proposed algorithm generates a CAPTCHA that offers better accuracy and lower machine attack rates compared to existing approaches.","PeriodicalId":101532,"journal":{"name":"2014 International Conference on Advances in Communication and Computing Technologies (ICACACT 2014)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132044573","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}

Thereby, giving rise to the query whether this escalating load can be managed by this cloud model or not. Cloud workload management is one of the primary challenges which must be addressed in the cloud computing paradigm. Instantaneous and concurrent requests from various clients to access the cloud application over the internet can generate bottlenecks moreover delay in response. This Paper presents an efficient dynamic technique along with the system architecture to solve this issue and also utilization function is given to measure the cloud server utilization. It allocates the client requests systematically and uniformly with the help of Host Controller by checking certain parameters such as request rate and server utilization. An even distribution criterion is defined in order to check whether any server is overloaded or underloaded. Thus, the utilization and performance of the system will improve and response will be given quicker.","PeriodicalId":101532,"journal":{"name":"2014 International Conference on Advances in Communication and Computing Technologies (ICACACT 2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122807604","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}
