[ns] tuning up wireless phy layer

[Balazs Kovacs]

Hi All,

I am simulating some communication performance with 802.11. My simulations 
always fail to show the results I expect because the wireless-phy seems to 
be overloaded. Is there any possibility to tune the throughput? I set 
datarate and basicrate to 54 mbps but this cause very slight improvement, 
while setting these rates to higher values makes no sense and no better 
results. I have 2.29.

Increasing simulation area and number of nodes cause much worse results. 
With AODV on a 1000x1000 area with 140 nodes and 30 parallel CBR flows 
(64byte*10/sec) I get more than 10 percent packet loss.

Any idea?

Thanks,

Balazs
