Hi,
I am running a MANET simulation (AODV, 802.11) in ns2.33. During my simulation, I get the following output from ns2:
Client 50: Handoff Attempted
Client 36: Handoff Attempted
Client 89: Handoff Attempted
[…]
It seems that this error message comes from mac/mac-802_11.cc. Could someone explain that to me? I would guess that the handoff is only applicable when using access points, but not in ad-hoc mode. Do I use the correct MAC protocol for MANET simulations? What is that Mac/Multihop protocol?
Thanks!
Here some of my parameters:
set opt(chan) Channel/WirelessChannel
set opt(prop) Propagation/TwoRayGround
set opt(netif) Phy/WirelessPhy
set opt(mac) Mac/802_11
set opt(ifq) Queue/DropTail/PriQueue
set opt(ll) LL
set opt(ant) Antenna/OmniAntenna
set opt(ifqlen) 50 ;# max packet in ifq
set opt(rp) AODV
