Most existing RF fingerprinting techniques have used high received SNR signals for generating the profile RF fingerprint of the transmitters and promising classification results has been reported in the literature. However, receiver SNR changes due to mobility of the transmitter/receiver and environment. Therefore, the RF fingerprints changes with the received SNR of the signals, which affect the classification results of the RF fingerprinting. This paper analyzes the effect of the receiver SNR on the overall RF fingerprinting classification. Three scenarios are considered, where profile RF fingerprint is generated by training the classifier with low, high and low/high SNR signals. These three scenarios correspond to the situation, when either transmitter or receiver is mobile and SNR changes from low to high or vice versa. The testing results show that accurate classification largely depends on the received SNR signal. Whereas high receiver SNR yields accurate results but high SNR is not typical in a wireless environment.","PeriodicalId":396084,"journal":{"name":"2012 15th International Multitopic Conference (INMIC)","volume":"925 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133321877","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}

One of the main reasons is insecure routing protocol. Generally ad-hoc network operations utilize reactive routing protocol such as AODV, to complete their routing needs. The route construction phase of this protocol is vulnerable; the malicious node easily disrupts the communication. In one case malicious node sends bulk route request (RREQ) packets to void addresses that occupy the network resources. This type of attack is called RREQ Flooding Attack (RFA). There are various schemes to mitigate the RFA but they are inadequate towards mitigating the attack. One of the main issues present in majority of proposed solutions is not to recover malicious node after punishment. This paper introduces RFAP, a scheme for mitigating the RREQ flooding attack in MANET by utilizing AODV protocol. The RFAP is an amended form of AODV. The scheme is specially design for MANET that has higher node mobility. Recovery of malicious nodes after reasonable punishment is the main objective of the scheme. Simulations are performed using NS-2 simulator and results are presented. These results illustrate that RFAP has ability to separate the flooder node from the network with more reliable as compare to simple AODV.","PeriodicalId":396084,"journal":{"name":"2012 15th International Multitopic Conference (INMIC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132539914","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}

Theoretically, various security solutions are designed to protect the valuable information of mobile users. But, its power, memory and processing constraints, high response time and authentication latencies are the main challenges for the researcher to develop and integrate standard security mechanisms in it. It is observed that, most of mobile users are not technical enough to configure security parameters and even already developed libraries do not support extended security features like transparent handling of certificates, verification of identities, and distribution of certificates. In this paper, an innovative and comparatively efficient protocol is designed and implemented. It does not only overcome the shortcoming of the certificate handling in mobile devices but also provides some extended certificate related features like registration, authentication and trust delegation. The designed GLCMP is lightweight because all complex and computation-intensive operations, involved in creation of certificate request in PKCS#10 standard format, are offloaded to a proxy server. It also provides domain based secure registration and verification of the identities without exchanging any confidential information to the proxy servers and even no user's credential is exchanged on network for authentication. After analyzing its performance, we noticed that authentication latency of GLCMP is 0.394 sec which is less than previously proposed protocols like NSI (4.7), PKI (5.01), and PKASSO (5.19 delegation time + 0.082 authentication times). We also formally verified our designed by using Z-Notation Modeling techniques and found that it is protected against man-in-the-middle, replay and impersonation and non-repudiation attacks.","PeriodicalId":396084,"journal":{"name":"2012 15th International Multitopic Conference (INMIC)","volume":"113 Pt A 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129694721","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 sheer variety of dialects that exist in any sign language makes it only harder to come up with a generalized sign language classification system. Though a lot of work has been done in this area previously but most of the approaches rely on intrusive hardware in the form of wired or colored gloves or are specific language/dialect dependent for accurate sign language interpretation. We propose a cost-effective, non-intrusive webcam based solution in which a person from any part of the world can train our system to make it learn the sign language in their own specific dialect, so that our software can then correctly translate the hand signs into a commonly spoken language, such as English. Image based hand gesture recognition carries sheer importance in this task. The heart of hand gesture recognition systems is the detection and extraction of the sign (hand gesture) from the input image stream. Our work uses functions like skin color based thresholding, contour detection and convexity defect for detection of hands and identification of important points on the hand respectively. The distance of these important contour points from the centroid of the hand becomes our feature vector against which we train our neural network. The system works in two phases. In the training phase the correspondence between users hand gestures against each sign language symbol is learnt using a feed forward neural network with back propagation learning algorithm. Once the training is complete, user is free to use our system for translation or communication with other people. Experimental results based on training and testing the system with numerous users show that the proposed method can work well for dialect-free sign language translation (numerals and alphabets) and gives us average recognition accuracies of around 65% and 55% with the maximum recognition accuracies rising upto 77% and 62% respectively.","PeriodicalId":396084,"journal":{"name":"2012 15th International Multitopic Conference (INMIC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128836755","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 Internet Archive is the largest organization based on a crawling approach in order to maintain an archive of the entire Web. The most important requirement of a Web crawler, specially when they are used for Web archiving, is to be aware of the date (and time) of last modification of a Web page. This strategy has various advantages, most important of them include i) presentation of an up-to-date version of a Web page to the end user ii) ease of adjusting the crawl rate that allows future retrieval of a Web page's version at a given date, or to compute its refresh rate. The typical way for this modification information of a Web page, that is, to use the Last-Modified: HTTP header, unfortunately does not provide correct information every time. In this work, we discuss various techniques that can be used to determine the date of last modification of a Web page with the help of experiments. This will help in adjusting the crawl rate for a specific page and also helps in presenting users with up to date information and thus allowing future versioning of a Web page more meticulous.","PeriodicalId":396084,"journal":{"name":"2012 15th International Multitopic Conference (INMIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128946675","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}
