Re: [ns] Adding new MAC protocol in NS2

Hi, Adding a new mac needs you to add it in the following files, referring to the Mac/802_11. tcl/lan/ns-mac-802_11.tcl tcl/lan/ns-mac.tcl tcl/lib/ns-mobilenode.tcl tcl/lib/ns-packet.tcl tcl/lib/ns-default.tcl Best, Pei

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 you

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 met
