Due to the dynamic vehicular traffic characteristics, the load at roadside access points varies with time. IEEE 802.11 DCF based MAC protocol shows substantial unfairness in this situation because of dynamic traffic load and multi-hop relay. The APs act as the relay nodes that needs to forward the relayed traffic as well as its own towards the gateway. In this paper an IEEE 802.11 DCF based MAC protocol is proposed that provides proportional fairness among the vehicular clients and roadside access points. Simulation result shows that the proposed scheme performs better than standard IEEE 802.11 DCF based MAC protocol in terms of fairness without loss in throughput.","PeriodicalId":285986,"journal":{"name":"2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128134945","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 paper presents a novel approach for offline signature verification. The proposed technique is based on the grid features extraction. For verification, the extracted features of test signature are compared with the already trained features of the reference signature. This technique is suitable for various applications such as bank transactions, passports etc. The threshold used in the proposed technique can be dynamically changed according to the target application. Basically, the threshold here is the security level which the user can input as per his requirement. The proposed technique deals with skilled forgeries and has been tested on two databases: Database A and a standard Database B (Set 1 and Set 2). The proposed technique gives FAR of 9.7% and FRR of 17.9% for Database A, FAR of 12.6% and FRR of 10.2% for Database B (Set 1) and FAR of 13.5% and FRR of 10.8% for Database B (Set 2) which is better than many existing verification techniques.","PeriodicalId":285986,"journal":{"name":"2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114415652","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 is a very popular tree based classification algorithm, used to generate decision tree from a set of training examples. The heuristic function used in this algorithm is based on the concept of information entropy. We are proposing two new heuristic functions which are better than the one used by C4.5 Algorithm by some way or the other. First heuristic function is better in terms of execution time. Second heuristic function is more realistic, gives importance to realistic attributes and thus gives more accurate and reasonable results. So in this way we are proposing two new improvements over J48/C4.5 Algorithm.

ElGamal encryption/decryption algorithm is based on the difficulty of discrete logarithm problem where it is straight forward to raise numbers to large powers but it is much harder to do the inverse computation of the discrete logarithm. Now, there are so many algorithms available which can solve the discrete logarithm problem of small size numbers in a reasonable time. So to improve security, we proposed a Modified ElGamal Cryptosystem Algorithm (MECA) to enhance the security for encrypting long messages and also secure against mathematical and brute-force attack as well as Low-Modulus and Known-Plaintext attack on Elgamal. The security of this algorithm is based on the difficulty of solving the discrete logarithm problem and Integer factorization problem.

There exist various schemes like digital watermarking algorithm etc. In this paper we have proposed a new algorithm to enhance the security in visual cryptography. To achieve this level of security, we have proposed a Cover Image Share Embedded security algorithm (CISEA) to produce the meaningful shares from the secret image. In this algorithm we have applied a new concept for generation of compliment images of a cover image over which the shares of secret image are to be embedded. CISEA provides one more layer of security for the images in communication channel. It is shown that CISEA provides better security compared to security provided by visual cryptography using digital watermarking system and the results are tested using MS visual studio dot net platform.","PeriodicalId":285986,"journal":{"name":"2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011)","volume":"60 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120921029","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}

To address this problem, we have presented a framework for effective image retrieval by proposing a novel idea of cumulative learning using Support Vector Machines (SVM). It creates a knowledge base model to increase the training samples by simply accumulating the samples based on user interactions. As we know relevance feedback (RF) is online process, so we have optimized the learning process by considering the most positive image selection on each feedback iteration. To learn the system we have used SVM. The main significances of our system are to address the small training sample and to reduce retrieval time.

It is a very successful clustering method whose subtle variations are involved in various clustering related applications. Despite its success, it shares a disadvantage with almost all of its contemporary pattern discovery algorithms — computational complexity. With the explosion in multimedia data over the internet and growing storage systems, there is a lot of research done in content based data retrieval. Fuzzy C-means is an integral part of this goal but its innate complexity makes it a strictly offline algorithm. Online pattern discovery is the need of the hour and our paper aims to address this issue without the use of powerful servers for implementing Fuzzy C-Means (FCM). We aim at accelerating the algorithm using Graphical Processing Units (GPUs), which are basically graphic cards common in desktop computers. We aim at restructuring the algorithm in a manner in which maximum data parallelism could be extracted thus utilizing the resources of the GPU to the fullest extent.
