Hallo all, My theme is connecting the two discrete event simulators. So where can i get the information about the scheduled events captured in the ns-2 source code. Is it been seen from the scheduler itself or else at the different parts of the protocol stack schedule the events. Also give me suggestions regarding the scheduling in ns-2.There are 4 types of scheduling methods used but which is advantageous one? Advance thanks. regards Arunkumar.

I believe that after fixing your first "major" bug, your next NS2 hacking experiences will be done a lot faster. One very important helper for beating the NS2 learning curve is to study the other NS2 success stories, to try to grasp all the details and lessons learnt. These could be right the thing that one will need either tomorrow... or in a year's time. Now that you have the protocol working, you might want to combine and parametize the test script so that it is able to run both protocols in the exact same scenarios. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf > Of Paul Vincent Craven > > A while back I asked about getting data to move from my wireless base > station node to my wired node.

The fixed routing protocol should have done it for you, on the fixed part of the network. Try other fixed routing protocols without your fix, to check what's happening: # http://www.isi.edu/nsnam/ns/doc/node304.html # types of protocols: Algorithmic / Direct / Dummy / DV / LS / Manual # Session / Static In this process you may find that the bug was your's, which is strange because your hierarchal addresses are OK, eg: 0.0.0 (W(0)) wired link 1.0.0 (BS) wireless link 1.0.1 (MH) your you might find a bug on the NS2 (step 7 of http://tagus.inesc-id.pt/~pestrela/ns2/ns2_debugging3.html) > 2.)

I've compared your code to DSDV's and NOAH's, and I can't understand why you couldn't use the same method: NOAH_Agent::forwardPacket (Packet * p) ... target_->recv(p, (Handler *)0); //line 985 ...
