Network coding performance: An emulation experiment

Abstract

This paper compares the performance of network coding to a baseline protocol that uses OLSR, SPF and NORM. The performance of each protocol suite is characterized in a three-hour militarily-relevant network topology using five (emulated) applications: video, voice, file transfer, situation awareness and messaging. Network coding provides comparable performance while using substantially less bandwidth. Simplified example scenarios are presented to provide insight into the reasons for network codingpsilas improved performance.
