Abstract

Video transferring over Heterogeneous Networks has been considered as one of the most significant subject to study because this process involve in a great number of new applications, which contributed in increasing the number of the users for this type of network. Transferring video in this type of network may suffer from many problems such as connection failures, weakness in the network layer, fading, network traffic overload, storage capacity, and so on. This study involves analyzing video transmission over heterogeneous using Network Simulation-NS2, the main errors which have occurred during video transferring, the types of video transmission techniques error correction methods, and various performance parameters such as the packet delivery ratio, throughput, normalized overhead control, and peak signal to noise ratio. The effect on the quality of the delivered video are calculated, and the results show that the quality of video transmitted over heterogeneous networks has improved using the proposed algorithm.

Abstract

A Mobile Ad-Hoc Network (MANET) consists of a number of mobile nodes that are connected dynamically without any infrastructure. In this network type, the use of the clustering technique significantly reduces the routing traffic that occurs during the routing process. Clustering is used to divide an ad-hoc network into small sets of nodes, where each cluster consist of a cluster head, ordinary nodes and gateway nodes. Clustering can be used for the effective utilization of resources for large ad-hoc networks. This paper measures the impact of using clustering strategy in MANET and how this strategy can enhance the performance of this network, and resulted in increasing the calculated quality parameters, like throughput, packet delivery ratio, end-to-end delay and normalized control overhead. This study produced a simulation for Low-Energy Adaptive Clustering Hierarchy (LEACH) which is considered one of the clustering based routing protocols. A comparison is done between LEACH with the other types of routing protocols such as AODV, DSDV and OLSR which are considered non-clustering routing protocol. Conclusion and discussion of the simulation results have demonstrated the importance and effect of using clustering in MANETs.
