Several distributed algorithms have been proposed in literature to solve fundamental problems such as mutual exclusion and leader election in distributed systems. When more than one algorithm is invented to solve the same problem particularly in asynchronous distributed systems, their performance is compared mostly based on the message complexity. This paper reviews the concept of message complexity and offers more clarity by studying the performance of the two most popular distributed algorithms - Ricart-Agrawala's algorithm and Raymond algorithm designed to solve the mutual exclusion problem. The paper has four main contributions (i) observes how the message complexity is understood and computed in the asynchronous distributed system so far and exposes its elusiveness; (ii) offers a more suitable definition of message complexity; (iii) briefly presents the simulator designed to study the performance of the distributed algorithms using the refined metric; and finally (iv) discusses about the simulation study to illustrate the significance and usefulness of the proposed metric.","PeriodicalId":311953,"journal":{"name":"2014 International Conference on Parallel, Distributed and Grid Computing","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122874098","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}

Mobile computing enables innovative applications through the sharing of computing resources among mobile devices such as notebook, smart phones and Personal Digital Assistant (PDAs) without any pre-existing infrastructure. Mobile computing includes a number of technologies and devices. The state of the user, static or mobile, does not affect the information management capability of the mobile platform. A user can continue to access and perform data manipulation during the state of mobility by using mobile computing devices. Delivering data packets between pair of processors is a primary responsibility of any mobile computing network. This activity is performed using a routing strategy. Maximize reliability of the data packets always a major concern while transmitting the data from one point to another point. In mobile computing it is the process of determining the data path through the network that data packets will move from the one computing device to another computing device. Routing strategy for data transmission is an important factor for achieving high degree of reliability. Multiple data packets are move within a network from source to destination in order to execute on available processing units with the objective of getting maximum reliability of data packets. This research paper present a routing strategy to achieve maximum data packets transmission reliability in mobile computing network during the data transmission.","PeriodicalId":311953,"journal":{"name":"2014 International Conference on Parallel, Distributed and Grid Computing","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131506389","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 case is even worse for detection of heterogeneous anomalies like epileptic seizures. Authors have presented robust expert system design for classification of epileptic seizures automatically with an improvement over the existing systems. The developed scheme illustrates selection methodology for feeding energy, entropy and standard deviation feature sets to the support vector classifier. The results display maximum classification rate of 99.53 % with sensitivity and specificity rates above 98.8 %. These results were validated over 10 folds of sub-divisions using rotation estimation technique with minimum computation time noted to be 0.0131 s. Therefore, the expert system developed during this study holds promising grounds for automated clinical diagnosis in real time.","PeriodicalId":311953,"journal":{"name":"2014 International Conference on Parallel, Distributed and Grid Computing","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130572140","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}

Also, excessive use of digital data in various fields of life demands a secure system. Various techniques such as cryptography, steganography and watermarking have been established. Among these steganography provides better confidentiality as it is the practice of hiding data within data. In digital media steganography, text files, images, audio as well as video are used as carrier. We focus in this paper on digital audio as the carrier. In this paper, a survey on latest audio steganographic methods is carried out along with their strength and weakness. Also, comparison between various steganographic methods based on robustness is carried out. Another contribution of this paper is evaluation of performance of various reviewed steganography techniques.","PeriodicalId":311953,"journal":{"name":"2014 International Conference on Parallel, Distributed and Grid Computing","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115023502","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}

It exploits the dependencies among the variables and represents the higher dimensional data in the lower dimensional with more amenable form, without losing a countable information. In this paper, we present a new image compression technique that uses PCA and Huffman coding. The input image is first compressed by using PCA, few of the principal components (PCs) are used to reconstruct the image, while the other less significant PCs are ignored. The reconstructed image is further quantized with dither to reduce contouring, occurred due to less number of PCs are used in image reconstruction. Finally, the Huffman coding is applied on quantized image to remove coding redundancy. The proposed image compression technique is applied on several test images and results are compared with JPEG2000. Comparative analysis and visual results clearly show that the proposed technique performs better than the JPEG2000.","PeriodicalId":311953,"journal":{"name":"2014 International Conference on Parallel, Distributed and Grid Computing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133248440","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}
