[ns] problem with setting link cost in link state routing

2007-10-31 Thread Abdul Jabbar
Hi, I have a question regarding the link state routing (rtProtoLS) implementation for wired networks in ns-2.31. Yes, I did check the documentation and searched ns2 mailing lists. I know that this particular code is not well documented, as is mentioned in the ns2 documentation and I canno

most wireless scenarios, the BER is assumed to be 10^-6. By the way, why are you posting this in ns-users list? Abdul. 林泰邑 wrote: > for example : > when I give ber=10^-3, packet size=1000bytes, what is PER? > > -Original Message----- > From: Abdul Jabbar [mailto:[EMAIL PRO

As far as I know, the relationship between BER and PER , assuming that bit errors are independent and uniformly distributed is, PER=1-(1-BER)^N where N is the number of bits. However, the above formula is only approximate because in real life scenarios, the bit errors are not completely indepe

I see the same problem. However, if you use the make-scen.csh script the directory ~/ns2.29/indep-utils/cmu-scen-gen/setdest, it works just fine. Also you could use the bonnmotion tool to generate node movement files. It is has more features than setdest utility. Hope it helps. Cheers. Abdul.
