In other words, business organizations need to be proficient in advertising their products to attract the potential consumers. To achieve the goal, organizations have to keep track of the consumers' buying habit to figure out the priority products. Thus the consumers' priority product management is a candidate for high degree of attention. In this paper, we have developed and analyzed the algorithm for consumers' priority product management with minimum time and space complexity. We use the concept of balanced binary search tree in this case to attain efficient time complexity. For reducing space requirement, we have proposed merging algorithm that incorporates with the balanced binary search tree, to achieve the optimal performances. We have simulated for 1 million test cases and our results show that the algorithm achieves a high memory saving index with logarithmic time complexity in each working round.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115785078","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 emergence of various radio access technologies and wireless data communication networks has revolutionized the entire telecommunications industry. By and large, 3G UMTS has become a major wireless cellular technology and IEEE 802.16 WiMAX has been widely accepted as a convenient alternative to the conventional mobile communication networks. In mobile communication systems, handoff/handover controls are critical to ensure a seamless migration as devices move from place-to-place. This paper analyzes the performance of the existing types of handover applied in the third generation mobile networks and compares them with handover used in WiMAX.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116165220","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}

TCP ensures that transfer of data and packets will be delivered in the same order as they were sent. The network topology is designed in a wireless network environment which is IEEE 802.11. TCP is a connection-oriented, end-to-end reliable protocol which is existing in our network topology. In this simulation the total number of nodes is 10. Reno, New Reno are generally used in a network topologies to control congestion. But in these cases Packet Delivery Fraction (PDF) is not sufficient, delay is high, packet loss is also high as it takes longer time to detect and recover packet loss. In order to improve retransmission scheme we propose an updated version of New Reno. It does not have to wait for 3 duplicate acknowledgements, thus it can retransmit faster and doesn't reduce the window size too much prematurely. For evaluating this performance we use NS-2.34 which is the most suitable network simulator in wired and wireless network environment.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124506507","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}

Gender characteristic plays an important role on the performance of ASR. If there is a suppression process that represses the decrease of differences in acoustic-likelihood among categories resulted from gender factors, a robust ASR system can be realized. In the proposed method, we have designed a new ASR incorporating the Local Features (LFs) instead of standard mel frequency cepstral coefficients (MFCCs) as an acoustic feature for Bangla by suppressing the gender effects, which embeds three HMM-based classifiers for corresponding male, female and geneder-independent (GI) characteristics. In the experiments on Bangla speech database prepared by us, the proposed system has achieved a significant improvement of word correct rates (WCRs), word accuracies (WAs) and sentence correct rates (SCRs) in comparison with the method that incorporates Standard MFCCs.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124055726","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 aim of those antennas is to produce some directive and switched beams rather than producing Omni-directional pattern since these beam patterns are considered to be wastage in some non-used or low traffic areas. Hence, the antenna systems producing the directive and switched beams should be highly preferred for the WLAN application. A smart antenna array system performs the adaptive beam forming by focusing the beam in the desired direction and creating nulls in other directions to avoid the interference and the wasting of the beams. This is performed by the operating the phase shifting in its feed network and different ports. This paper investigates the performance of the different array patterns with different phase shifting for the optimum performance of the WLAN applications in a high congested indoor environment.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115965917","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}

We model the fading channel using Jakes Doppler power spectrum and AJakes Doppler power spectrum. The performance of these different modulation techniques is analyzed in terms of bit error rate (BER) for single and multipath Rayleigh fading channel in outdoor environment by MATLAB simulation. For the simulation of fading channel the different property values e.g. path delays, average path gains, maximum Doppler shifts, Doppler spectrum parameters etc are chosen properly to a reflect realistic fading channels. In all the cases, our analysis shows that MQAM performs better and the system performance increases with the use of maximum likelihood sequence estimation (MLSE) equalizer over Rayleigh and Ricean Fading channels.","PeriodicalId":127060,"journal":{"name":"2012 15th International Conference on Computer and Information Technology (ICCIT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128154024","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}

Driven by these key thinking, we have thought of a home appliance controlling system — touch based smart home which augments the users real life experience. In this paper we describe the development of a prototype that uses the augmented reality based on touch controlling system to control the daily home appliances in a smart home.
