A region with maximum sum of an attribute value is useful in different decision making problems, for which no efficient solution has yet been found. For selecting a region of such interest, there are lots of unique regions in both 4 and 8-Adjacency region rules. In case of 4-Adjacency rule, for selecting a 10-cell region, more than 288 thousand unique regions can be found among one will be a region with maximum sum value. The scenario suggests that the problem falls in the class of NP-Hard decision problems, so the problem is complex in nature as we deal with the computation terms of the algorithm to be designed in polynomial time. This research contains a new dynamic programming approach for the problem, whose focus is on the efficiency for finding approximate solutions. Experiments have suggested that with the data input of images having higher degree of spatial auto correlation, the algorithm is quite useful and practical in nature, as it was tested with real life data and has extracted maximum value regions with thousands of cells in a sufficient time.","PeriodicalId":166149,"journal":{"name":"2012 10th International Conference on Frontiers of Information Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121696645","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}

Techniques for optimizing power usage in WSNs have been developed in this paper. The goal is achieved by exploiting a decrease in cross-over distance between error correcting coded (ECC) information signals and its un-coded version. A decrease in total energy gain is observed from the practical data acquisitioning. From analysis presented in this paper, the overall 22% energy gain in ECC coded data was observed with the theoretical analysis and results obtained using MATLAB. The modulation schemes under test were MPSK, MFSK and MQAM. Furthermore, the presented idea has opened ways for researchers to exploit other means to bring a decrease in cross-over distance so that further gain of energy in WSNs can be possible.","PeriodicalId":166149,"journal":{"name":"2012 10th International Conference on Frontiers of Information Technology","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124541158","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}

Critics of cyclomatic complexity argue that complexity changes with modularization of code. If the technology is shifted from linear programming to OOP and SOA, the complexity of code will also change. The cyclomatic complexity was for the first time introduced by TJ McCabe as metric for the measurement of complexity of a piece of code. McCabe calculated the complexity of a sample code written in fortran language. Fortran is a linear programming language and there are no functions and classes in this language. Hence at the time of introducing cyclomatic complexity there was no concept of structured languages and object oriented languages. This is ignored in McCabes's cyclomatic complexity due to which it is not enough to measure complexity for advance programming architectures like OOP and SOA. Further work has been done on the complexity of structured, OOP and SOA but still work is required on SOA. This study proposes a new metric for the measurement of complexity of WCF a SOA. The significance of this new metric is that it can help to estimate cost of a new project, maintenance cost of already existing projects, basis path testing, comparison of two projects and many other factors.","PeriodicalId":166149,"journal":{"name":"2012 10th International Conference on Frontiers of Information Technology","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134065328","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}

Circumferences consist of many pixels, what is the relation of radius size and number of pixels on the circumferences with and without redundancy? We mainly discuss the condition about how to make a unique desirable circle with three nonlinear pixels in images and the above-mentioned relation.

Transmission Control Protocol (TCP) is the standard network protocol for communication in the Internet, but its performance drastically degrades over wireless networks, as TCP takes packet drop or collision as a sign of congestion. In this paper, we analyze TCP's performance over wireless networks using NS-2 Simulator. Unlike traditional performance evaluation methods for TCP over wireless networks, we consider different versions of TCP over different routing protocols. Moreover, we also consider the effectiveness of TCP both over infrastructure-based and infrastructure-less wireless networks. Simulation results show that TCP's performance varies from scenario to scenario both in infrastructure-based and ad-hoc wireless networks.","PeriodicalId":166149,"journal":{"name":"2012 10th International Conference on Frontiers of Information Technology","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124535231","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 order for the reader to uniquely identify all tags within certain range, some sort of anti-collision mechanism is required. ALOHA and its variations can be used in such a scenario. EPC Global, a standardizing body for RFID technology, has proposed a Dynamic Framed Slotted ALOHA mechanism for UHF passive tags (Gen 2, Class I), and a 'Q' algorithm is used to dynamically update the size of the frame, where the size changes exponentially. Two parameters that define this Q algorithm are the initial size of the frame and the speed of frame-size estimation. In this paper we present a complete RFID system simulator which can be used to investigate various algorithms in various scenarios, in context of UHF RFID systems, and then present our simulation setup, results and analysis where the throughput for different traffic scenarios is calculated. Based on the results the trend and the optimal values are discussed for the two parameters. These results can be used by an RFID system designer to choose the right initial parameters, based on an order-of-magnitude estimate of the traffic conditions.","PeriodicalId":166149,"journal":{"name":"2012 10th International Conference on Frontiers of Information Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126437978","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}
