Cost effectiveness, flexibility and usability among others are the driving force behind its widespread and adoption. However, it is a challenge to achieve high quality video with limited bandwidth. In this paper, we present an experimental evaluation and study in order to understand how the main video quality parameters such as the frames per second, resolution and the bit rate affects the video quality over the Internet.

Genetic Algorithm is a method that mimics the process of natural evolution; it was used to support the Intrusion Detection Systems. Genetic Algorithm contains several elements such as population size, evaluation, encoding, crossover, mutation, replacement and stopping criterion. Elements specifications must be determined before using Genetic Algorithm. The performance of Genetic Algorithm depends mainly on these specifications. The aim of this paper is to compare different types of genetic operators and monitor their performance in Intrusion Detection System, to determine the Selection type and Crossover type to be worked together and perform better.

Intrusion Detection System (IDS) is a system used to detect attacks, Steady State Genetic Algorithm (SSGA) is applied to support IDS by supplying the rule pool with additional data, these data can be used in testing phase to detect the attacks. The main goal of this research is to enhance Replacement steady state genetic algorithm to detect intrusions. This enhancement has been achieved by comparing replacement methods. This research proved that the Triple Tournament Replacement is better than Binary Tournament Replacement to increase Detection Rate and there are no effects on False Positive Rate. In this research represent the results of DR equal 100% for three types of attack (DoS, Probe and R2T), and 53% for U2R.

Intrusion Detection System used to detect the attack. Genetic Algorithm used to support IDS. Fitness Function is helpful in chromosome evaluation which is a Genetic Algorithm part. The problem is to find a suitable Fitness Function for a chromosome evaluation to get a solution for Intrusion Detection. This paper suggests a new reasonable Fitness Function using Reward-Penalty technique to evaluate population chromosomes efficiently. This technique used to give reward to the good chromosome and to apply a penalty on the bad chromosome. This paper will show the Fitness Function, discuss it and compare it with another Fitness Function to check its validity.

This realization can in turn lead to propose an optimal video adaptation algorithm that gives the user the best video quality for a certain network conditions, which is of high importance especially in todays congested and lossy networks.
