Two Techniques For Fast Computation of Constrained Shortest Paths
A major obstacle against implementing distributed multimedia applications such as web broadcasting, video teleconferencing and remote diagnosis, is the difficulty of ensuring quality of service (QoS) over the Internet. A fundamental problem that is present in many important network functions such as QoS routing, MPLS path selection and traffic engineering is to find the constrained shortest path that satisfies a set of constraints. For interactive real time traffic, t ....etc

COMPUTATIONALLY EFFICIENT SERIAL COMBINATION OF ROTATION-INVARIANT AND ROTATION COMPENSATING IRIS RECOGNITION ALGORITHMS
Abstract:
Rotation compensation is one of the computational bottlenecks in large scale iris-based identification schemes, since a significant amount of Hamming distance computations is required in a single match due to the necessary shifting of the iris codes to compensate for eye tilt. To cope with this problem, a serial classifier combination approach is proposed for iris-based identification, combining ro ....etc

A System for Peer-to-Peer Video Streaming in Resource Constrained Mobile Environments
Introduction
 Peer-to-Peer based near-live video streaming is becoming popular with users of fixed-line broadband.
 Unavailable to mobile users because they cannot meet the bitrates requirements.
 P2P-TV system enables users in a physical proximity to retrieve video chunks in a cooperative way.
 The coordinated and efficient usage of all wireless resources available to a group of mobil ....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

TWO TECHNIQUES FOR FAST COMPUTATION OF CONSTRAINED SHORTEST PATH

Abstract: Computing constrained shortest paths is fundamental to some important network functions such as QoS routing, MPLS path selection, ATM circuit routing, and traffic engineering. The problem is to find the cheapest path that satisfies certain constraints. In particular, finding the cheapest delay-constrained path is critical for real-time data flows such as voice/video calls. Because it is NP-complete, much research has been designing heuristic algorithms that solve the ....etc

Abstract
A fundamental problem in wireless sensor networks is to maximize network lifetime under given energy constraints. In this paper, we study the network lifetime problem by considering not only maximizing the time until the first node fails, but also maximizing the lifetimes for all the nodes in the network, which we define as the Lexicographic Max-Min (LMM) node lifetime problem. The main contributions of this paper are two-fold. First, we develop a polynomial-time algorithm to derive the LMM-optimal node lifetime vector, which effec ....etc

We present a method to compute the delay-constrained multicast routing tree by employing chaotic neural networks. The experimental result shows that the noisy chaotic neural network (NCNN) provides an optimal solution more often compared to the transiently chaotic neural network (TCNN) and the Hopfield neural network (HNN). Furthermore, compared with the bounded shortest multicast algorithm (BSMA), the NCNN is able to find multicast trees with lower cost. ....etc

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

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