hi,everyone today I revise a little in one routing protocol, before I revised ,the source code linkes follow: ch->next_hop_ = -1; //Broadcast address which means next hop is broadcast address,I want to indicate the next hop,for example,the topology likes this node 0 -> node 1 —> node 2 ,so node 0's next hop is node 1 so I revise the code linkes this if(index_==0) ch->next_hop_ = 1 else (index_==1) ch->nedxt_hop_=2 I do this in order to fix the next hop,however,I recompile the ns2,everything goes ok, but I use the same script to do the experimental, the screen display : segementation fault (core dumped) I check related website,and get the information that I may visit the memory I did not declared, I think may be I use the node address as the ip address! could any body tell me why ? so Urgent!
