With the growth of each technology, the related security issues become of particular importance. Being IP-based and playing a signaling role in VOIP networks, SIP protocol lets the invaders use weaknesses of the protocol to disable VOIP service. One of the most important threats is denial of service attacks, a branch of which in this article we have discussed about is flooding attack. These attacks make server resources wasted and deprive it from delivering service to authorized users. Distributed denial of service attacks and low rate attacks can mislead many attack detection mechanisms. In this paper, we have presented an anomaly based method in order to detect and prevent flooding attacks by using Entropy. In this method we examined the VOIP network traffic with the help of entropy. Entropy makes it possible for us to accurately detect the changes in the network traffic and identify the attacker or attackers with the help of the Compressed summarized table of packet data (Sketch). The proposed method is fully implemented and has been tested using the Spirent server. The results of our implementation show the proposed method was able to detect distributed and low rate flooding attacks accurately, without causing significant delay and overhead on the SIP server.","PeriodicalId":152540,"journal":{"name":"2014 4th International Conference on Computer and Knowledge Engineering (ICCKE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125967414","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}

This article presents a simple method that has lower calculations for center process unit to achieve results as well as faster reaction time and high accuracy. Many method exist in speech signal classification which have their own advantages and disadvantages with regard to their application. In this paper, we propose a new method in speech classification based on human auditory system mixed to spectrogram features. The basilar membrane filters or auditory filters are often modeled by a gammatone function which provides a good approximation to experimentally determined responses. The filter bank derived from these filters is referred as a gammatone filterbank and since STFT can also be likened to a filterbank analysis, these will be an interesting link between standard STFT and gammatone filterbank. A popular tool in time-frequency analysis is spectrogram. Using gammatone filterbank in spectrogram, the method interchanges the fixed filters in all bands and approaches a new diagram called Gammatonegram.","PeriodicalId":152540,"journal":{"name":"2014 4th International Conference on Computer and Knowledge Engineering (ICCKE)","volume":"666 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122966727","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}

Owing to these two facts, the concept of vehicular cloud computing has been shaped up in the recent years in which cloud services are offered through underutilized resources of vehicles that construct a dynamic groups of autonomous vehicles and therefore create a cloud. The difference between this set-up and conventional structures of cloud computing lies in the mobility of nodes which leads to change in the dynamics of resource availability over time. The goal of this study is to offer an application scheduling model for determining the optimum response needed for management of dynamic vehicular cloud resources in a way that tasks are completed with minimum cost; before their deadlines and within the lifetime of the cloud. To solve the aforementioned problem, a binary integer program model is formulated here, and the impact of changes in various parameters such as different tasks costs, application deadlines, types and lifetime of created clouds are analyzed and evaluated. The presented results, specify and highlight the factors that should be taken into consideration in the process of application scheduling and demonstrate how our proposed optimization model could result in reliable solutions for the vehicular computing optimization problems.","PeriodicalId":152540,"journal":{"name":"2014 4th International Conference on Computer and Knowledge Engineering (ICCKE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127585735","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}

Due to the appealing features of skin segmentation algorithms, they are widely used in different biometric applications such as face detection, face recognition, face tracking, hand gesture recognition, etc. However, several challenges such as nonlinear illumination, equipment effects, personal interferences, ethnicity variations, etc are involved which have been yielded to the inefficiency of many color based methods. Even though several interesting ideas have already been proposed, the problem has not been satisfactorily solved yet. This paper introduces a skin segmentation technique that addresses limitations of the earlier works. The proposed system consists of some steps including initial seed generation of skin map, Otsu segmentation in color images and a super two stage diffusion method. The initial seed of skin pixels is provided based on the idea of ternary image as there are certain pixels in images which are associated to human complexion with very high probability. The Otsu segmentation is performed on Cb and Cr of YCbCr color space, I of YIQ, H of HSV, a of Lab, u of Luv and c of Lch and the result accompanying with the edge map of the image is utilized in diffusion stage in order to annex initially unidentified skin pixels to the seed. Both quantitative and qualitative results demonstrate the effectiveness of the proposed system in compare with the state-of-the-art works.","PeriodicalId":152540,"journal":{"name":"2014 4th International Conference on Computer and Knowledge Engineering (ICCKE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131434947","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}
