Dear all,
In the function "Node::get_node_by_address()" defined in node.h, the input
should be ip address or mac address? If it is ip address, how can I get the
ip address of the node in the mac layer? Thank you very much!

Dear all,
I am simulating sensor networks using ns-2.29. The modulation and
propagation model in ns-2 are quite simple (~ns2.29/mobile/modulation.cc,
tworayground). Can anyone tell me how to calculate the BER/PER of packets
according to SNR and even implement multipath fading channel model in
Dear all,
I am new in ns-2, I try to simulate a wireless ad-hoc scenario using ns-2. I
notice that in the phy. model of ns-2, as long as the received power is
greater then some threshold, it is assumed the packet is received
successfully. I wonder if there are more realistic models for it, e.g
Yes. If the packet the routing layer is processing now is denoted as p,
p->txinfo_.getAntenna() will return your antenna properties.

Dear all,
I found the trace2stats software from ns2 user's mail list. But the link to
download it in the original message is not accessible anymore. Does anyone
know the new link to download it? Or is there any other software available
to calculate network statistics (like throughput and good
Dear all,
In ns-2.29, there is a MAC protocol called MAC/Simple. My Question is if we
can use this protocol in wireless ad-hoc simulation. I tried it in an ad-hoc
scenario with 50 nodes, CBR traffic, combined with different routing
protocol (DSDV, AODV, DSR). The trace file showed no data pack
Dear all,
Does anyone have successful experience in using MAC/Simple for wireless ad
hoc simulation? I wrote the following script to run simulation. When I set
the MAC type as MAC/802_11, the simulation ran just fine. But when I set the
MAC type as MAC/Simple, segmentation fault was reported.
I got similar question as Alaeddine. For example, if I want to compare the
performance of TCP and UDP under some scenarios, which kind of application
should I attach?
Regards,
Kai

Dear all,
I am simulating an ad-hoc wireless network scenario. I put 50 mobilenodes in
a 400*420 area, including one cbr source node in the bottom and one
destination node in the top. I use Shadowing as propagation model and set
simulation time to 1000. I set the RXThresh_ to a 80m transmiss
