Cognitive Networks are an emerging new type of networking technology that can utilize both Radio Spectrum and Wireless Station. Based on the Knowledge of the availability of such resources gathered from past experience the resources can be utilized efficiently. Signaling is the major issue in Cognitive Network. Multiple Input Multiple Output (MIMO) technique is used for the transmission of signals in Cognitive Network. In this paper, the performance of MIMO in a scattered environment is analyzed and water filling algorithm is used to maximize the capacity of MIMO channels. We also propose an optimum beamforming algorithm to design beamforming vectors such that, interference caused by the primary transmitter to the cognitive receiver and the interference caused by the cognitive transmitter to the primary receiver is completely nullified while maximizing the rate of both primary and secondary links. The proposed technique does not require any changes in the existing environment between the primary and secondary user. The secondary user will be allowed to transmit concurrently to the primary user. Since the primary user is a licensed one it need not to have any knowledge about the resources utilized and performance of the secondary user and it transmits independently. Further it is also proved that the rate of Cognitive Multiple Input Multiple Output (MIMO) link implemented by the proposed beamforming algorithms is equal to interference free Multiple Input Single Output (MISO) link.","PeriodicalId":119498,"journal":{"name":"2013 International Conference on Green High Performance Computing (ICGHPC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114259245","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}

As this model depicts the electricity billing it is often termed as utility computing. It offers various services to the client based on the need. The need of the resources can be scaled up or down on the basis of the requirement. The IT sectors started using cloud service models. As the use of cloud increases day by day the concerns of cloud also gets increased. There are number of data breaches that are happening day by day that affect the cloud growth. The major concern in adapting cloud is its security. The companies have lot of data that gets increased each day enlarges the complication of data privacy and security. The data that we talk can be classified as either stagnant data i.e., for simple storage as offered by Amazon's Simple Storage Service (S3) or it can be vibrant that changes often. The solution available to protect the stagnant data will be to simply encrypt the data before it gets stored in the server. In order to solve the issues of vibrant data the techniques are being proposed to work out on the encrypted. This paper is a survey of different security issues that affects the cloud environment and related work that are carried out in the area of integrity. The technique proposed combines the encrypting mechanism along with the data integrity check mechanism. The data are double wrapped to ensure no data leakage happens at the server side. The data are also shared with users with proper access mechanism.","PeriodicalId":119498,"journal":{"name":"2013 International Conference on Green High Performance Computing (ICGHPC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117116352","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}

Apart from the security, there is another requirement in transmission is effective and efficient delivery of data. USOR uses ordinary distance calculations to get the knowledge about neighbour nodes. At the same time we can't incorporate the entire information about the network into single node or every node. We know that nodes in ad-hoc network have limited storage and battery power. Already half of the power vested in security, remaining power has to be used for calculating routes and data transmission. For that we are merging the above USOR with Better Approach To Mobile Ad-hoc Networking, or B.A.T.M.A.N. which is a routing protocol that has the knowledge of its best route alone - no single node has all the data. This technique eliminates extending the information to the concerning network changes to every node in the network. Each node only maintains the best hop details not the entire network topology. From this we are achieving fast transmission of data in a secure way with minimum node failure rate.","PeriodicalId":119498,"journal":{"name":"2013 International Conference on Green High Performance Computing (ICGHPC)","volume":"59 17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123939075","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}
