Dear all
I am using ns 2.34 on red hat linux. All the wireless simulation codes on
AODV or existing protocols are working fine. But when I am adding new
protocol, I am able to make the simulator fter running ./configure make
clean make. But during execution of tcl file with new protocol code I am
getting following errors. I have carefully implemented code step by step by
thoroughly reading ns material on internet and ebooks. I shall be highly
thankful to you.
