Read the section of transmission models in NS-2 manual. You should
check which transmission model (e.g. FreeSpace, TwoRayGround, Shadowing)
is in use. You should try to adjust the RXThreah_ using threshold.c as
described in the NS manual.

In the two-ray ground model,the receiver power at distance d is given by
following formula:
Pr(d) =Pt * Gt * Gr * ht^2 * hr^2 / (d^4)
where ht is the transmitter antenna height and hr is the receiver antenna
height. If the distance between sender and receiver is relative large, the
formula can
Hi,
adjusting transmission power and thresholds is not sufficient for such a
long distance. You also need to adjust MAC timeout values.

Hi,
you have to follow this two steps procedure:

May I trouble you for ask you some question , I try to increase Transmission
rage is 1600 m by increase Pt but It still can communicate in 500 m range ,
