Here is the nice script for measuring packet loss rate, jitter and end-to-end delay in the prof. Chih-Heng Ke's website.

How to measure the throughput, packet drop rate, and end-to-end delay for UDP-based application over wireless networks is given here

There are two service sets in IEEE 802.11 standard. The basic service set (BSS) for the infrastructure mode and the Independent Basic Service Set (IBSS) for the ad-hoc mode.
The BSS is a single access point (AP) together with all associated stations with the AP. In the infrastructure WLAN , communications can only take place between the AP and the other members of the BSS.
In the ad hoc networks, all of the stations those are within each other's transmission range is called an IBSS.
Problem: While executing NAM in NS2 following error appears.
nam:
[code omitted because of length]
: no event type or button # or keysym
while executing
"bind Listbox
%W yview scroll [expr {- (%D / 120) * 4}] units
}"
invoked from within
"if {[tk windowingsystem] eq "classic" || [tk windowingsystem] eq "aqua"} {
bind Listbox
%W yview scroll [expr {- (%D)}] units
}
bind Li..."
Solution:
patch -p1 < ./tk-8.4-lastevent.patch
4. install again (with ./install command)
Now it works perfectly.
(If there is a problem on patching, change -p1 to -p0. )
The best open source tool for network simulation is NS2. The first step to learn NS2 is to it. Cygwin gives linux like environment on Windows. Here is the step by step procedure how to install NS2:
