We propose and analyze a scalable and efficient cluster-based group key management protocol for secure group communications in mobile ad hoc networks. For scalability and dynamic reconfigurability; we take a cluster-based approach by which group members are broken in to cluster-based subgroups and leaders in subgroups securely communicate with each other to agree on a group key in response to membership change and member mobility events. We show that secrecy requirement for group communication is satisfied. Further, there exists an optimal clus ....etc

Abstract Given a data point set , a query point set , and an integer , the Group Nearest Group (GNG) query finds a subset ( ) of points from such that the total distance from all points in to the nearest point in is not greater than any other subset ( ) of points in . GNG query is a partition-based clustering problem which can be found in many real applications and is NP-hard. In this paper, Exhaustive Hierarchical Combination (EHC) algorithm and Subset Hierarchial Refinement (SHR) algorithm are developed for GNG query processing. W ....etc

Optimizing the Rekeying Cost for Contributory Group Key Agreement Schemes
Abstract
Although a contributory group key agreement is a promising solution to achieve access control in collaborative and dynamic
group applications, the existing schemes have not achieved the performance lower bound in terms of time, communication, and
computation costs. In this paper, we propose a contributory group key agreement that achieves the performance lower bound by
utilizing a novel logical key tree structure, called PFMH, and the concept of pha ....etc

Abstract
File Transfer Protocol (FTP) is a standard network protocol used to copy a file from one host to another over a TCP/IP-based network, such as the Internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server. FTP users may authenticate themselves using a clear-text sign-in protocol but can connect anonymously if the server is configured to allow it.
The first FTP client applications were interactive command-line ....etc

Image Transfer Protocol for Internt
IEE/ACM Transactions on Networking, Vol. 10, No. 3, June 2002
Language: Java

Abstract:
Images account for a significant and growing fraction of Web downloads. The traditional approach to transporting images uses TCP, which provides a generic reliable in-order byte-stream abstraction, but which is overly restrictive for image data. We analyze the progression of image quality at the receiver with time, and show that the in-order delivery abstraction provided by a TCP-based approach prevents the re ....etc
