Dear P.Navaratnam, I have the same problem , Have you solved it....please let me know if you overcome it.
According to me: I select the shadowing model as propagation model for wireless link. In this model you can specify the loss ratio ( just read chapter 18 in ns-doc.pdf file) if you solve it by other way let me know please. ********************************************************************* Hi, Could anyone please tell me how to configure error models with a wireless channel in ns2.28. Actually I tried it as mentioned in the manual like this: $ns node-config -IncomingErrProc UniformErrProc proc UniformErrProc {} { set err [new ErrorModel] $err unit pkt $err rate_ 0.02 return $err } But it is giving error. Please help me to solve it. Thanks PBA ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
