The importance of wireless communications has been growing. Performance is a most relevant issue, resulting in more reliable and efficient communications. Security is crucially important. Laboratory measurements are made about several performance aspects of Wi-Fi (IEEE 802.11 b, g) WEP point-to-point links. A contribution is given to performance evaluation of this technology under WEP encryptio...

In this paper we propose and evaluate a Medium Access Control (MAC) protocol for the efficient integration of high quality video traffic with ftp data packet traffic over a wireless cellular channel of very high capacity. We envision a system where the mobile terminals are considered to be high performance devices with extended storage capabilities which can act like cache memories streaming mu...

A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication between these mobile nodes is carried without any centralized control. The ease of deployment and the infrastructure less nature of Mobile Ad Hoc Networks (MANET) make them highly desirable for present day multi media communications. In this paper we analyze the performance of TCP/IP based application protocol ...

LIGAND is a composite database comprising three sections: ENZYME for the information of enzyme molecules and enzymatic reactions, COMPOUND for the information of metabolites and other chemical compounds, and REACTION for the collection of substrate-product relations. The current release includes 3390 enzymes, 5645 compounds and 5207 reactions. The database is indispensable for the reconstructio...

In this paper we are presenting the internet based data acquisition system which will be comparatively low in cost and can be flexible to serve for different applications by connecting different modules. Key module in the system is embedded board which communicates via GPRS which eases it’s accessibility from any place in the world through a web server built into the board. Using FTP server rem...

Large-scale genomic sequencing requires a software infrastructure to support and integrate applications that are not directly compatible. We describe a suite of software tools built around the Common Assembly Format (CAF), a comprehensive representation of a sequence assembly as a text file. These tools form the backbone of sequencing informatics at the Sanger Centre and the Genome Sequencing C...

In this paper, a new ranking method known as median is used to convert fuzzy transportation problems crisp valued and then solve them by using the Max-Min technique. We can apply both types of numbers such odd even numbers. Using method, we reach an optimal solution balanced well unbalanced FTP.

FTP currently provides two commands for handling mail. The MAIL command allows a user to send mail via the TELNET connection (the server collects the mail and determines its end by searching for the character sequence "CRLF.CRLF"). The MLFL (mail file) command allows a user to send mail via the data connection (requires a user-FTP to handle the command but transfer is more efficient as server n...

In response to a need for a general catalog of genome variation to address the large-scale sampling designs required by association studies, gene mapping and evolutionary biology, the National Cancer for Biotechnology Information (NCBI) has established the dbSNP database. Submissions to dbSNP will be integrated with other sources of information at NCBI such as GenBank, PubMed, LocusLink and the...
