[ns] Packet loss effect on End2End Delay
Hi All, is there any effect of packet loss on End2End Delay in OLSR routing protocol? For example if a routing protocol has more packet loss then wat about the end2end delay..either it will be increasing or decreasing with packet loss? Thanks in advance Muhammad Saleem Khan Ph.D(CS) , COMSATS Institute of Information Technology, Islamabad. Cell No# 0346-9754454

Re: [ns] Ns-users Digest, Vol 109, Issue 27
Can some one help me to locate how to get topology line work? I find the set topology [...] unreasonable since the telecommunication protocols in the NS software cannot get changed, Usually 3D topology is highly important right? I want to locate the directory which helps to set topology and try to change that by using OPENGL C++. Thanks.

From tcl you can use this command to get some particular vlaues in the trace file for example I want to get only cbr values, so the command is set tracefd [open | greo \ cbr \ out.tr w] this will record all the cbr values, so use it for what ever values you need.

[ns] analyse trace file for accessing the channel
Hi I have multiple nodes which they broadcast periodically. I need to know the number of times which a node in this scenario attempt to access the channel but it was busy. I want to know the percentage of time in which the channel was busy( Channel Busy Ratio) How can I find and extract this information from the trace file? Regards, Hanna
