[ns] certain questions

[neeraj gupta]

i am just trying to simulate your paper "Available Bandwidth in IEEE802.11b Network Based on Non-Intrusive Measurements" there are certain question i need to ask.
1.It is written "To the nodes which have send the several packets during a single period, the NAV fields is the sum of the the NAV values to all successful packets sent by this node" the question is whether the current node in question is transmitting the packets to the one particular node or it is sending the packets of itself to destination and other packets (as router) to all other nodes also?
2.the duration field in question is of the RTS packet or of the data packet
3. the flag value who's value can be true or false, why we have taken
the value of NAV as Tdata if the transmission is unsuccessful.
4. how have you find the neighboring nodes in ns-2 and what routing protocol are you taking to find whether the transmission is successful or not.
It will niece of you if you can kindly sent me the code or explanation to above question at the earliest. Since i am taking your paper as a base for my research and need to sent in the progress report to mu guide.
