you might want to report the bugs to the monarch mailing list at
monarch@monarch.cs.cmu.edu

mobility features (combined from sun/cmu implementations) in ns would look
very similar to the cmu version with aditional features from sun.

so the list would go somethng like the foll:

* wireless channel with radio propagation models (capture,hidden terminal
interference, gain, modulation etc)
* network interface controlling channel access
* LL (with ARP) and MAC protocols
* adhoc routing protocols (DSR,DSDV (cmu) and AODV(sun), and more in
  future)
* mobile IP implementation
* mobilenodes with multiple channel access and having 3D trajectory
* grid keeper - basically a central, node movement tracking tool

Hopefully I have covered them all,
