Studying the performance and the Efficiency of random linear network coding in achieving the reliable transfer of data in losing wireless networks


Abstract in English

Wireless networks suffer from frequent loss of packets for many reasons such as interference, collision and fading. This makes wireless medium unreliable medium for data transfer. The main methods for ensuring the reliability in this medium are using transmission control protocol (TCP) and the automatic repeat request (ARQ). Recently, network coding has been found as new technology that changes the traditional forwarding method (Store- and- Forward) in the networks to more effective and intelligent method (Code- and- Forward), which contributes to the increase of both capacity and throughput of these networks. In this research, random linear network coding is used as promising technology that aims to achieve the reliable transfer of data in losing wireless networks, and studying the enhancement that this technology presents to the performance of these networks in unicast and multicast transmission. For evaluating the efficiency of this technology and comparing its performance with the performance of reliable transfer protocols, we use the networks simulator (NS3). Simulation results showed that random linear network coding achieve the reliable transfer of data with bigger throughput and less delay and number of transmission compared with the protocols (TCP, ARQ).
