ABSTRACT
A randomized algorithm is defined as an algorithm that typically uses the random
bits as an auxiliary input to guide its behavior. It achievs good performance in the
average case. Formally, the algorithm's performance will be a random variable
determined by the random bits, with (hopefully) good expected value. The worst case is
typi ....etc

In the age of multimedia and high-speed networks, multicast is one of the mechanisms by which the power of the Internet can be further harnessed in an efficient manner. It has been increasingly used by various continuous media applications such as teleconferencing, distance learning, and voice & video transmission. Compared with unicast and broadcast, multicast can save network bandwidth and make transmission more efficient. In this seminars, we will review the history of the multicast, present you several existing multicast routing algorithms ....etc

This paper provides a heuristic algorithm for an NP-Complete problem. It is a result of a research on an NP-Complete problem known as Clique problem. I have succeeded in developing an algorithm which will give the maximum size Clique, for a given graph G, as its output. This paper explains the algorithm, its time complexity, applications and its implementation in C. This is a research paper based on an interesting class of problems known as ?NP-Complete? problems. No polynomial-time algorithm has yet been discovered for an NP-Complete problem, ....etc

Mesh Algorithms in Parallel Processing

¢ Parallel processing is processing a task with several processing units, or many processors

¢ Most powerful computers contain two or more processing units that share among themselves the jobs submitted for processing

¢ Several operations are performed simultaneously, so the time taken by a computation can be reduced.

¢ A problem to be solved is broken into a no.of subproblems. These subproblems are now solved simultaneously, each on different processors. The results are then combi ....etc

When reference signal for the FxLMS algorithm is taken from an acoustic sensor convergence can be very slow due to great eigen value spread. Using a non acoustic sensor, Such as a tachometer, cancellation of narrow band noise in the sensed fundamental frequency and harmonically related ones can be achieved very fast, although other periodic noises and underline broad band noise will remain.

Backward prediction errors resulting at the various stages of an adaptive lattice predictor(ALP) represent a a time-domain orthogonalization of the input ....etc

Abstract—IEEE 802.16 OFDMA systems have gained much attention for their ability to support high transmission rates and broadband access services. For multiuser environments, IEEE 802.16 OFDMA systems require a resource allocation algorithm to use the limited downlink resource efficiently. The IEEE 802.16 standard defines that resource allocation should be performed with a rectangle region of slots, called a burst. However, the standard does not specify how to construct bursts. In this paper, we propose a heuristic burst construction algorithm ....etc

HEURISTIC ALGORITHMS FOR DESIGNING SELF-REPAIRING PROTECTION TREES IN MESH NETWORKS


ABSTRACT:

Protection trees have been used in the past for restoring multicast and Uni-cast traffic in networks in various failure scenarios. In this paper we focus on shared self-repairing trees for page link protection in Uni-cast mesh networks. Shared protection trees have been proposed as a relatively simple approach that is easy to reconfigure and could provide sub-second restoration time ....etc

Heuristic and Metaheuristic Algorithms


Heuristic algorithms – What are they?

Wikipedia says:

In computer science, a heuristic is a technique designed to solve a problem that ignores whether the solution can be proven to be correct, but which usually produces a good solution or solves a simpler problem that contains or intersects with the solution of the more complex problem.

Heuristics are intended to gain computational performance or concep ....etc

In this technical paper we present a study of the various routing algorithms, which are in use presently. This study of present algorithms is limited to their general working and the various security problems, which they are unable to solve. Our main emphasis is on discussing a novel approach based on Leap-Frog cryptographic signing protocol and that how this novel approach deals the various security threats, which, its predecessors (using traditional public-key signature schemes) are unable to withstand.
