Performance Evaluation of Network Coding for Wireless Ad-Hoc Network

Abstract

Network Coding is a new field for research, which has been growing rapidly. Its ability for improving network throughput and robustness enhancement (losses, link failure and other drawbacks). Hence the allow coding at intermediate nodes between the source and the receivers in one or multiple communication sessions. Differing from previous practice as the intermediate nodes used to receive stores and retransmit. The simulation of different topologies and traffic patterns in order to provide better understanding of network coding behavior has been conducted. The first portion of this project is compression of network coding versus traditional flooding in realistic Mac layer. The results show that network coding has advantages over flooding show in improved Packet Delivery Ratio. We observed that the performance using network coding is strongly dependent upon the topology, node density and the number of packet in each combination. The next portion is the study performance of network coding using different type of Mac led to gathering different results and comparing them with respect to performance. The results revealed malfunctioning current of realistic Mac layer The study concluded that this methodology might be the promising solution to gradually eliminate the variety of drawbacks of the system as a whole.
