A heuristic method of designing a network is achieved by scheduling algorithm which is based on network parameters such as interference free transmissions, and optimization of avoidable scheduling sets. We derive a joint linear optimization problem which is used in the designing of the wireless network. Further when the scheduling is done, the network coding is adapted. The code construction algorithms are used and the unequal timeshare is incorporated in designing network codes. The paper demonstrates the variation in the network performance parameters like Throughput, Energy efficiency, Delay, Packet Delivery Ratio, Overhead, and Normalized Overhead. The statistics is madeby varying the network modeling parameters with different node densities. After the network coding, based on the traffic flow, the sleep state is introduced where the network goes to the hibernated mode. A unique joint optimized structure is required for MAC scheduling and network coding. A heuristic approach of scheduling is needed to avoid hidden station problem. Also to provide an energy and throughput optimization for multi hop wireless network.","PeriodicalId":272955,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING AND COMMUNICATION (ICSC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124799360","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 has suggested a novel approach for developing an automatic, adaptive, fast and reliable system capable of recognizing enrolment number and corresponding marks of student from answer sheet and storing it in the host computer. This system consist a hardware which picks out sheets one by one from a bundle and captures image of the front page of each answer script. This image is processed by proposed robust extraction and noise removal algorithm adaptive to environmental conditions. It is then passed through Optical Character Recognition (OCR) system which extracts characters using correlation. Accuracy of system depends on the sample space size of OCR system. In our experiment we have archived average 81% accuracy in various light and paper (Exam-Sheet) condition. We had trained the OCR with 50 samples of numerals set (0-9). In this way developed system will not only replace the traditional tiring way of manual writing of marks in database but in addition can calculate average marks of all students, ranges of marks for assigning different grade and provide grade for each student automatically.","PeriodicalId":272955,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING AND COMMUNICATION (ICSC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130965233","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}

However most of the SOC systems are synchronous designs and the issues like clock skew, power consumption and EMI are related to clock network. Asynchronous circuits can offer benefits like reduced power and improved performance. However implementing whole design with asynchronous design style is a challenge due to lack of CAD tools. The GALS (Globally-Asynchronous Locally-Synchronous) design methods brings compromise between synchronous and asynchronous design styles by separating each synchronous blocks in SoC with asynchronous interface. Each synchronous block in SoC can perform operation with its own local clock. The data communication among synchronous blocks can be achieved via handshaking signals after pausing the local clocks. Though these GALS system architectures ensures less dynamic power through clock less asynchronous interface the leakage power contribution to total power equation is still a challenge in deep submicron technologies. Power gating is most effective technique for synchronous design to address leakage power. In this paper an asynchronous power gating sequence generation is proposed for GALS synchronous blocks which has to wait long time for data. To corroborate the proposed technique a synthesis flow is proposed to implement asynchronous 8051 micro controller. The implementation was done using Synopsys SAED 90 nm libraries and the experimental results shows 30% leakage power reduction for power gating blocks.","PeriodicalId":272955,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING AND COMMUNICATION (ICSC)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134043110","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}
