 === Description ===
-N.N.
+Data from a performance measurement study carried out in a 802.11 wireless mesh network. The network uses the OLSR protocol in conjunction with the ETX metric. The study was conducted to evaluate the quality of service in terms of throughput, packet loss, latency, and jitter and the dependency of these parameters on the routing metric.
