In this paper, we provide an open-source software emulator setup for MANETs and study its ¯delity in providing reliable performance estimates for real-time tra±c. We emulate the IEEE 802.11 MAC/PHY (DCF) using the EMANE software emulator deployed on a cluster and run experiments for dif- ferent multi-hop wireless scenarios. As an instance, we study the performance of real-time streaming media over a mesh network supported by OLSR. We also use the setup to analyze the impact of the wireless network on the self-similarity of the traffic.
