 Hi, 
    I am trying to simulate 
handoff algorithms in a Wireless LAN, need some help on the 
following: 
1.    I wish to know if ns (i am 
using 2.1b8) takes into account latency when a mobile node moves between 
domains. 
2.    Instead of using distance 
as given in Marc Greis' tutorial, can I make the mobile node periodically check 
the signal strength of the Base Station as it is moving from the domain of one 
BS to another? 
3.    I hope to monitor the 
performance of my handoff algorithm by checking the latency, number of lost 
packets and BER (any error models which i can use?). Any one knows if this can 
be done?  
    I will really appreciate it 
if someone can give me some pointers on the above cos I am only a 10-day old 
ns-user. 
Thank you so much, 
Kerwin.
