Abstract”
Computer supported collaborative applications on overlay networks are gaining popularity among users who are geographically dispersed. Examples of these kinds of applications include video-conferencing, distributed database replication, and online games. This type of application requires a multicasting subnetwork, using which messages should arrive at the destinations within a specified delay bound. These applications also require that destinations receive the message from the source at approximately the same time. The problem ....etc

INTRODUCTION

Consider a scientist who is responsible for the operation of robotic meteorological station located on the planet Mars (Fig. 1). The weather station is one of several dozen instrument platforms that communicate among themselves via a wireless local area network deployed on the Martian surface. The scientist wants to upgrade the software in the weather stationâ„¢s data management computer by installing and dynamically loading a large new module. The module must be transmitted first from the scientistâ„¢s workstation to a ....etc

Pict-Message Message Visualizer
Pict-Message is a project for people who wish to explore in an innovative and rather surprising way the different data feeds that form the building blocks of today’s virtual world. By pointing the application, let’s say, to the CNN news feed, you will receive the last news in real time - rendered in pictures. The application will choose for each in-coming word an image from flickr’s or google’s database tagged with corresponding keywords. Since the application searches and brow ....etc

Multicast Routing with Delay and Delay Variation Constraints for Collaborative Applications on Overlay Networks

Maximum variation in the delays from a source to the destinations. The time-complexity of our Algorithm is O (|E| +nk log (|E|/n) +m2 k), where n and |E| are the number of nodes and edges in the network, respectively, k is the Number of shortest paths determined, and Abstract”Computer supported collaborative applications on overlay networks are gaining popularity among users who are geographically dispers ....etc

CONTINUOUS MESSAGE DELIVERY DISSEMINATION

1.1 Abstract:
In the Continuous Delivery Message Dissemination (CDMD) problem, each message has a length and is partitioned into packets, however, the packets of every message must arrive at its destination in its “original” order, and all packets for each message must arrive during consecutive time units. To cope with intractability, efficient Message dissemination approximation algorithms for classes ....etc

Message IntegrityandMessage Authentication


MESSAGE INTEGRITY


The cryptography systems that we have studied so far provide secrecy, or confidentiality, but not integrity. However, there are occasions where we may not even need secrecy but instead must have integrity.

Topics discussed in this section

11.1 Document and Fingerprint
11.2 Message and Message Digest
11.3 Difference
11.4 Checking Integrity
11.5 Cryptographic Hash Function Criteria

Introduction
Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different sets of physical and operational constraints; wide variations in transmission latency are particularly troublesome. The proposed Interplanetary Internet, which must encompass both terrestrial and interplanetary links, is an extreme case. An architecture based on a least common denominator protocol that can operate successfully and (where required) reliably in multiple disparate e ....etc
