Dear All, I think I found a bug in channel.cc file when I try to implement frequency hopping scheme. So I need to add and remove nodes from wireless channel dynamically.
In WirelessChannel::removeNodeFromList(MobileNode *mn) for (tmp = xListHead_; tmp->nextX_ != NULL; tmp=tmp->nextX_) { I think it should be. for (tmp = xListHead_; tmp != NULL; tmp=tmp->nextX_) { I fixed it and I remove core dump. Best Regards, Weetit
