[ns] how to find where a variable is initialized

Hi, everyone, How to find where a variable is initialized ? I add a new mac same as mac-802_11, but it puts warning MAC_RMAC: accessing MAC cache_ array out of range (src 0, dst 1, size 0)! I found out that it is due to cache_node_count_ = 0. It must be set somewhere in MAC/802_11, but I do not

Re: [ns] How to access mac layer in c++ of ns2

Hi, I have never done anything with TCP layer, so I'm not sure. But a general rule I summarized is that 1) If the two layers you want to cross-access are adjacent, you can use uptarget_/downtarget_ 2) If they are not, it is a bit of difficult to make the pointer clear. My

Re: [ns] Please help me to solve my issue in ns2

Hi, I don't think you want to classify packets in mac layer. Instead, you want your packets to be submitted to aodv. Thus, in aodv.cc, you need to identify your packets in AODV::recv(Packet *p). In fact, as you know, all packets first arrive at such a recv function in any layer. So if
