Especially, cooperative communication in wireless sensor networks (WSNs) has gained so much interest due to the limitations of WSNs. This paper proposes a new cooperative communication method for WSNs in port logistics according to the observation of real application in port. In our proposed method, we use some fixed agents to help the sensor nodes to gain more efficient communication in the network. The simulation results and analysis show that our method achieves a good performance in enhancing the transmission and energy efficiency, resulting in improvement of the communication performance of the whole network.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122827464","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}

Orthogonal codes are employed to encrypt the given input images so that multiple encoded images can then be mixed together to save storage space or transmission bandwidth. The multiplexed and encoded image is further encrypted employing multiple reference-based joint transform correlation. The address code is fed into four channels after performing phase shifting on them by different amount. The input image is introduced to the channels to obtain joint power spectra (JPS) signals through Fourier transformation. The resultant signals are phase-shifted and then combined to form a modified JPS signal which is then inverse Fourier transformed to yield the final and highly secure encrypted image. At the receiver, the image is Fourier transformed and multiplied by the address code used in encryption. Inverse Fourier transformation yields the multiplexed and encoded image which is then decoded using orthogonal codes. The proposed technique enhances the security performance by implementing orthogonal coding and nonlinear encryption algorithms so that no unauthorized access to or interception of information is possible. Performance of the technique is evaluated through computer simulation.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125442187","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}

In this paper some important assumptions are made to keep the formulae very simple. The most important assumption is that, the AP is providing service to client nodes with only one type of Access Category (AC) traffic at an instant. Comparing both the theoretically achieved maximum throughput and simulation results, for different access categories (ACs) and for different packet sizes we observed that the formulae is pretty much accurate except for only one test case.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121130518","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}

It is well known that the multipath fading phenomenon is an inherent characteristic of wireless channel. In this paper, it is shown how selection combining diversity scheme enhances reliability in wireless communication by minimizing the channel fluctuations due to fading. The simulation results show that the Signal-to-Noise Ration (SNR) varies between M-PSK and M-QAM but better SNR gain achieved as the number of receiving antenna increases like for two, three and four receiving antennas around 20–27 dB, 22–30 dB, 23–31 dB diversity gains are found respectively.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130030720","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}

It can act as a filter to discard sub-optimal objects. However, a major drawback of skyline is that, in datasets with many dimensions, the number of skyline objects becomes large and no longer offer any interesting insights. To solve the problem, recently k-dominant skyline queries have been introduced, which can reduce the number of skyline objects by relaxing the definition of the dominance. This paper addresses the problem of k-dominant skyline objects for high dimensional dataset. We propose algorithms for k-dominant skyline computation. Through extensive experiments with real and synthetic datasets, we show that our algorithms can efficiently compute k-dominant skyline queries.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"07 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134009736","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}

Digital filters of various kinds can be designed using this particular evolutionary technique. In this paper, we have studied the effect of an important control parameter namely, the Weighting Factor, on the convergence speed of the DE algorithm, associated with the efficient design of low-pass FIR filter being used subsequently as a pulse-shaping filter in a QPSK modulated system.
