| I see two options to do this:
| 
| 1.) wait for some time, then send one package to every 1-hop neighbor
| 
| 2.) distribute the packages over time
| 
| Option 1 does wake up the olsrd one once for all neighbors, but it sends a 
| burst of packages that might block some real traffic.
| 
| What do you think about the two options.

| the wlan card when receiving the unicast package)
