The intermittent connection, together, with the limited resources of mobile nodes, mainly power and memory, created a challenging environment for data networking in DTN. Routing protocols developed for DTN tend to discover and select the minimum end-to-end delay paths to destinations assuming that these paths provide the highest delivery rate. To achieve this goal, they spread many copies of the same packet, ignoring the limitedness of storage space and power sources. In this paper, we study this problem by building a mathematical model for optimal routing in DTN. We compare the results of implementing three objectives for this model: minimizing the end-to-end delay, minimizing the end-to-end number of hops, and maximizing the delivered messages. We study and analyze the impact of varying the buffer space, the traffic load and the packets time-to-live (TTL) on the three objectives. Results show that minimizing the number of hops provides higher delivery ratio than minimizing the delay, which contradicts the previous assumption. In addition, minimizing the number of hops significantly reduces the number of transmissions which results in saving energy.","PeriodicalId":436095,"journal":{"name":"2010 International Computer Engineering Conference (ICENCO)","volume":"16 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":"115413443","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}

Remote sensing images contain huge amount of geographical information that reflects the complexity of geographical features and spatial structures. Image mosaics covering large geographical regions at multiple resolutions are also becoming more prevalent. New techniques are needed to efficiently store and quickly retrieve such large datasets for interactive viewing on computers with physical memory many times smaller than the size of the data to be viewed. The pyramid data structure, known also as hierarchical architecture, provides a means of describing images at different level of details. In this paper, we are presenting a multiresolution tiling technique that uses Bounded Irregular Pyramid structure to represent in a compact form and store/retrieve remote sensing images for interactive viewing on a remote machine. In this study, the proposed representation, its encoding and decoding algorithms were developed and applied to remote sensing images; the fidelity and efficiency of the algorithms and their relationship with the spatial complexity of the images were evaluated.","PeriodicalId":436095,"journal":{"name":"2010 International Computer Engineering Conference (ICENCO)","volume":"66 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":"126259234","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}

At low resolution level, mutual-information (MI) based registration using similarity transformation model is performed. At high resolution level, scale invariant feature transform (SIFT) based registration is applied to accelerate registration convergence and to achieve good computational efficiency using rough parameters extracted from MI. To remove outliers automatically a RANdom Sample And Consensus (RANSAC) algorithm is applied. A comparison between proposed technique with hybrid registration approach using MI and SIFT in the spatial domain and with three wavelet-based registration techniques is achieved: point mapping registration, SIFT-based registration, and MI-based hierarchical registration. The quality of the registration process was measured using the following criteria: normalized cross-correlation coefficient (NCCC), percentage relative root mean square error (PRRMSE), and run time. The application of the selected techniques to dental panoramic X-ray images has shown that proposed wavelet-based approach combining MI, SIFT, and RANSAC algorithm gives the best results and can be used efficiently for registration of X-ray images. It gave 0.7805 NCCC, 0.1040% PRRMSE, and 22 seconds run time.","PeriodicalId":436095,"journal":{"name":"2010 International Computer Engineering Conference (ICENCO)","volume":"17 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":"115248601","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}
