However , for the last couple of decades , multiple-valued logic (MVL) such as ternary (base=3) or quaternary (base=4) logic styles has attracted considerable attention. MVL circuits can reduce the number of operations necessary to implement a particular mathematical function and further, have an advantage in terms of reduced area. As we progress into an era of nanotechnology , molecular devices are becoming promising alternatives to the existing silicon technology. Carbon nanotube field effect transistors (CNFETs) are being extensively studied as possible successors to silicon MOSFETs. Research has started in the earnest to understand the device physics of CNFETs as well as to explore possible circuit applications. Implementable CNTFET circuits have operational characteristics to approach the advantage of using MVL in voltage mode. In this paper through using of CNTFET characteristics, we presented new CNTFET circuit design to implement optimum quaternary Galois field logic.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130989517","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 have identified several low power strategies and applied them to realize a low power VLSI architecture suitable for motion estimation block in a video codec chip. For motion estima- tion we have adopted the TBHEX block matching algorithm [14]. Our proposed architecture has been synthesized with the Synopsis Design Analyzer tool and experimental results reveal that it requires only 22.14 mW power. Further our proposed architecture is area efficient with 30 K gate counts including memory within the chip boundary.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123132770","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 channel utilization, end-to-end delay and packet transmission rate of proposed burst assembly method are compared with those of existing burst assembly methods. A hybrid signaling scheme is used to implement the proposed burst assembly. The performance of hybrid signaling is compared with existing signaling schemes. However, just enough time (JET) signaling gives better performance than the hybrid signaling scheme. Therefore, a prediction technique is incorporated to use JET signaling scheme in the proposed burst assembly method. The prediction error occurring in this method is calculated and the average number of contentions encountered in the proposed burst assembly method is determined.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122228473","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}

While a solution to the hidden-terminal problem is paramount, a QoS- aware Medium Access Control (MAC) protocol must also provide a channel access mechanism that considers the QoS constraints of real-time flows. We propose a new MAC protocol called PFQAMP (Priority based Fairness provisioning QoS-Aware MAC Protocol) which supports QoS for real-time applications and provides fairness in accessing the channel. Nodes are assigned priorities dynamically based on i) their roles as sender, receiver or forwarding node and ii) type of the traffic they have to forward or send. Our approach ensures both QoS (through differentiating traffic types) and fairness (among the traffic in the same class). This leads to better network throughput, lower delay and avoidance of starvations for same priority traffic flow. Through simulation we show that our proposal outperforms IEEE 802.11 in terms of average throughput, delay and fairness.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134461765","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}

Collaboration and resource sharing form the basic ideologies of a grid, hence it becomes imperative that joining and leaving the grid becomes easy and any independent network of resources can collaborate with other operational grids. To utilize these geographically separated resources efficiently, it is important to have a robust system of discovering resources based on functional and non-functional requirements. The current information service of the Globus Toolkit 4.0 does not feature quality-of-service and the various service-level agreements of each node of the grid. This paper suggests solution for the issues of dynamic update of the grid resource information, and efficient, scalable and QoS-aware resource discovery in independent grids. In this paper, overlay architecture for resource discovery in a grid is proposed in which the functional and nonfunctional requirements are taken into account for resource discovery. The approach combines resource registration with SLA specifications and semantic discovery of resources with a desired QoS.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123785562","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 prob- lem statement is broken down, to describe discrete charac- teristics. Each landscape, described by its fitness landscape is used to optimize or amplify a certain characteristic or set of characteristics. Individuals from each of these pop- ulations are kept geographically isolated from each other. Each population is evolved individually. After a predeter- mined number of evolutions, the system of populations is analysed against a normalized fitness function. Depending on this score and a predefined merging scheme, the popula- tions are merged, one at a time, while continuing evolution. Merging continues until only one final population remains. This population is then evolved, following which the result- ing population will contain the optimal solution. The fi- nal resulting population will contain individuals which have been optimized against all characteristics as desired by the problem statement. Each individual population is optimized for a local maxima. Thus when populations are merged, the effect is to produce a new population which is closer to the global maxima.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130760520","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}
