The technology however imposes a challenge that is the increased complexity of channel equalization. Wireless channels are multipath fading channels, causing deformation in the signal. To remove the effect (imposed by channel) from received signal, the receiver needs to have knowledge of CIR (Channel impulse response) that is usually provided by a separate channel estimator. This paper is aimed at exploring the use of Neural Network (NN) as a tool for MIMO-OFDM channel estimation and compensation. The research attempts to gauges the usefulness of proposed system by analyzing different algorithms to train NN. Further to ascertain the performance of the proposed technique; length of the known training sequence has been varied over a reasonable range and observations are made. Finally, the results obtained by using different algorithms for training NN have been compared with each-other and against the traditional least squares channel estimator, which along with observations/comments form part of the paper.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117232035","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 this paper, we propose an Elliptic Curve Digital Signature Algorithm (ECDSA) based message authentication in a VANET. The operation sequence of the proposed scheme is as follows: 1) Source vehicle generates private key and public key. 2) Public key is made available to all the vehicles in the VANET. 3) Source vehicle creates a hash of the message using secured hash algorithm. 4) Secured has his encrypted using private key in the source vehicle ands ends it to the destination vehicle. 5) At the destination vehicle, the received encrypted message is decrypted using the public key. The result of the decryption will be the hash of the message. 6) Destination vehicle can then hash the message in the same way as source vehicle did and compare the two hashes. Using this proposed scheme, strong authentication policy is provided for the destination vehicle.Because hashing is relatively unique, any changes in the message would change the message hash.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123465872","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}

Work that we present in this paper has primarily as an objective of presented the adaptation and the implementation of one of advanced metaheuristic which is the Electromagnetism Metaheuristic (EM) applied to the systems of production of the type Hybrid Flow Shop (FSHs) for the scheduling and the assignment problem. Electromagnetism Metaheuristic is a recent method of optimization which takes its inspiration in the electromagnetic law (attraction and repulsion) of Coulomb on the charged particles. For this metaheuristic, we will start by presenting his general principle, its principle algorithm, its most important main features and parameters like its scopes of application. We will propose then an adaptation of this method to the discrete case on the scheduling problems of the production systems of the type Hybrid Flow Shop (FSHs). We present then the comparison between the metaheuristics (Genetic Algorithms (GA) and Particle Swarm Optimization method (PSO)), and the hybrid metaheuristic (Electromagnetism Metaheuristic EM) applied to the same FSHs problem. Finally we will present the results obtained by this method (EM) applied to FSHs for the two problems: scheduling and assignment.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124515314","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}
