This problem is challenging when the number of true user ratings is relatively small and unfair ratings plays majority in rated values. In this paper, we propose a new method to find malicious users in online reputation systems using Mean Bisector Analysis and Cosine Similarity (MBACS). Here the effort is mainly concentrated on abnormals in both rating-values domain and the malicious users domain. MBACS is very efficient to detect malicious user ratings and aggregate trustful ratings. The proposed reputation system is evaluated through simulations, MBACS system can significantly reduce the impact of unfair ratings.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124999392","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}

However, under the expected co-channel deployment of femto and macro-cells, a significant number of calls originating from femtocell users get dropped or blocked. This blocking rate problem must be controlled so that the femto users get quality of services. In this paper, the analytical system model is designed introducing a novel approach for solving Markov chain for increased number of femtocells. A channel selection algorithm along with power control is also being proposed in this paper to reduce the call dropping and blocking rates for femto users. Results demonstrate the effectiveness of the proposed method in reducing the blocking and dropping rates.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121510584","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}

High spectral efficiency is also achieved due to the orthogonality among all sub-carriers which overlap in the frequency domain. Two-dimensional (2-D) signal mapper and one-dimensional (1-D) inverse fast fourier transform (IFFT) are the major elements of the conventional OFDM communication system. In this paper, we use the concept of three-dimensional (3-D) signal mapper and 2-D IFFT which is called as 3-D OFDM communication system. The performance of 40 Gb/s 2-D OFDM-PON and 3-D OFDM-PON using multi-level modulation scheme under various system impairments is analytically analyzed for coherent optical orthogonal frequency division multiplexing (CO-OFDM) without using any optical dispersion compensation. As bit error rate (BER) depends on minimum Euclidean distance (MED) which is 15.46 % more in case of 3-D OFDM as compared to 2-D OFDM. Analytical result show that at BER of 10-3 which is the limit of forward error correction (FEC), there is about 2.5 dB signal-to-noise ratio (SNR) gain. An optical budget (downstream) of 47.1 dB is obtained for 40 Gb/s optical access networks using 2-D OFDM and about 48.4 dB for 3-D OFDM with 16-QAM and corresponding values are 45.3 dB and 46.5 dB respectively for 64-QAM.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"250 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113989807","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 detailed analysis of different voltages induced and currents flowing inside Zig-Zag transformer shows that Zig-Zag transformer provides low impedance path to zero sequence currents. In addition to that, the potential of the floating neutral of the Zig-Zag transformer connected to a three-phase source measured with respect to the neutral of that three-phase source equals the zero sequence voltage component of that source. This property can be used to get neutral current compensation in three-phase four-wire power distribution system even in presence of unbalanced and distorted voltages. As the neutral current (total zero sequence current) is being taken care by Zig-Zag transformer, a reduced rating DSTATCOM can be used for load balancing and unity power factor operation using instantaneous symmetrical components theory.
