Aqua-Sim on NS3

aqua-sim-ng's Issues

Question of Packet Loss

Hello!
During the experiment, I found that occasional packet loss occurred. Like this, node A sends a packet that Node B can receive, but node C does not. Nodes A, B, and C are usually able to communicate with each other, and packet loss is only a small probability event. The channel setting in the experiment is the default setting and the noise interference is AquaSimConstNoiseGen. I am not sure if this situation is caused by noise interference or by the node sending and receiving data conflicts. I would be very grateful if you can give your suggestion.
Thank you!

Some problems about the examples

Hi Robert,

I have installed the Aqua-Sim-NG with ns-3.26 on Ubuntu 16.04, but I have met some problems when I tried to run the examples.

My work path is: ~/eclipse-workspace/NS3

1. bMAC.cc
   the command line is: ./waf --run src/aqua-sim-ng/examples/bMAC
   It generated a trace file called "bMAC-trace.asc", but it didn't print any "Received a packet." sentence which is bind with the callback function (according to the line 177 in bMAC.cc). Below is the output:
   -----------Initializing simulation-----------
   Creating Nodes
   -----------Running Simulation-----------
   fin.

2. floodtest.cc
   the command line is: ./waf --run src/aqua-sim-ng/examples/floodtest
   But it seems like that the transmissions are not successful, and the callback function didn't work. Below is the output:
   -----------Initializing simulation-----------
   Creating Nodes
   Node: 0x10fee00 newDevice: 0x10e85b0 Position:(0,0,0) freq:25
   Node: 0x10ff690 newDevice: 0x10e9170 Position:(0,2000,0) freq:25

   (NetworkTotal) 0
   SendUp Pkts(Sink_RoutingLayer):
   (NetworkTotal) 0
   Recv Pkts(@Phylayer):
   (NetworkTotal) 0
   End.

3. GOAL_string.cc
   the command line is ./waf --run src/aqua-sim-ng/examples/GOAL_string
   It generated errors, below is the output:
   -----------Initializing simulation-----------
   Creating Nodes
   -----------Running Simulation-----------
   assert failed. cond="tAbsolute >= TimeStep (m_currentTs)", file=../src/core/model/default-simulator-impl.cc, line=236
   terminate called without an active exception
   Command ['/home/mac/eclipse-workspace/NS3/build/src/aqua-sim-ng/examples/ns3.26-GOAL_string-debug'] terminated with signal SIGIOT. Run it under a debugger to get more information (./waf --run --command-template="gdb --args %s ").

I'm sorry for bothering you, but it really confused me, look forward to your reply.

Thanks,

no packet send/recv in ddos example

i am trying to run the ddos example avialble in aquasim-ng. but no result found. simulation end with 0 network packet send/recv. kindly guide what is the possible reason.

The transmission distance problem.

I set the transmission range of node A to 3500m, but sometimes the nodes outside 4000m receive requests directly sent by node A. Every time node A sends a request packet, I print its transmission range , which is always 3500m, but that's what happened. Here is my code.

AquaSimChannelHelper channel = AquaSimChannelHelper::Default();
if (range>0){
channel.SetPropagation("ns3::AquaSimRangePropagation");
}
AquaSimHelper asHelper = AquaSimHelper::Default();
Ptr c = channel.Create();
asHelper.SetChannel(c);
....
if (range>0){
sink->GetPhy()->SetTransRange(range);
dev1->GetPhy()->SetTransRange(range);
dev2->GetPhy()->SetTransRange(range);
dev3->GetPhy()->SetTransRange(range);
dev4->GetPhy()->SetTransRange(range);

HH-VBF Implementation problem

Dear Robert Martin sir
I'm unable to implement HH-VBF using "aqua-sim-routing-vbf.cc" model.
Please help me out. Your help is highly appreciated.

I think transmission delay on receiver shouldn't be calculated

aqua-sim-ng/model/aqua-sim-signal-cache.cc

Line 85 in 0e89076

Time transmissionDelay = m_sC->m_phy->CalcTxTime(asHeader.GetSize());

if (m_mac == 0 || m_phy == 0 || /*m_app == 0 ||*/ m_node == 0 || m_phy || m_configComplete)

aqua-sim-ng/model/aqua-sim-net-device.cc

Line 177 in 0e89076

if (m_mac == 0 || m_phy == 0 || /*m_app == 0 ||*/ m_node == 0 || m_phy || m_configComplete)

I guess the second m_phy should be m_routing

Segmentation fault when run NDN modules

Hi!
I am trying to run NDN modules, and I just add one line codes, "SendPkt(packet);", in line 133 of named-data.cc, to send the packet form application layer. But some error occurs when run "named_data_example" and the gdb message are as follows:

-----------Initializing simulation-----------

fama doesn't send data packet

I made my scratch file that is similar to BroadcastMAC_example.
but it doesn't send data packet after receive CTS packet.
how can i fix it?

How to use AquaSimMultiPathSignalCache?

Hi Robert,

I have some problems with the AquaSimMultiPathSignalCache class:

1. First of all, how could I change the default signal cache from AquaSimSignalCache to AquaSimMultiPathSignalCache?
   I tried several methods:

Ptr<AquaSimMultiPathSignalCache> sC = CreateObject<AquaSimMultiPathSignalCache> ();
asHelper.SetPhy ("ns3::AquaSimPhyCmn",
			"PT", DoubleValue (5), /* W */
			"Frequency", DoubleValue (3), /* kHz */
			"SignalCache", PointerValue (sC));

or

Ptr<AquaSimMultiPathSignalCache> sC = CreateObject<AquaSimMultiPathSignalCache> ();
// or: Ptr<AquaSimSignalCache> sC = CreateObject<AquaSimSignalCache> ();
Ptr<AquaSimNetDevice> newDevice = CreateObject<AquaSimNetDevice> ();
newDevice->GetPhy()->SetSignalCache (sC);

sadly, neither are successful.

2. Even if I have replaced the signal cache with the AquaSimMultiPathSignalCache, I will get a vector of various paths associated with MultiPathInfo structure from the GetPaths() function, but how to use it?
   There are many influences in physical layer caused by "multipath problem", more than path delay, path gain, such as bit error rate or something else.

You may be very busy with your research, I am really sorry to trouble you with these problems.

Would it be possible to give me some advice to use the AquaSimMultiPathSignalCache class in AquaSim-NG?

Thank you, and I look forward to hearing from you.

Best regards,
Yiqian Xia

Enabling and Disabling localization in a UWSN simulation.

Dear Robert Martin,

In fact, it is not at all a bug or issue. Simply it is a doubt. I could not find any other person who can provide an answer to this doubt. So, I am raising it as a 'Issue' here. -Sorry.

The README.md mentioned about new localization feature available in aquasim-ng.

It seems that the 'aqua-sim-localization.cc' has AquaSimRBLocalization (Range-based localization) and it can be used to set a node as RefNode" to "Set as a reference node for localization" - but there is confusion in using this since there is no documentation available for it.

But, readme.md as well as the pdf documents of aquasim-ng were not showing any example case of using localization in a simulation.

1. How to enable and disable localization in a UWSN simulation?
2. If localization is enabled, then how to select one particular localization algorithm in a simulation?
3. If we are not enabling localization in a scenario that is using VBF, then it will use the exact locations provided by ns-3. Correct? If localization is enabled, will VBF use the estimated locations provided by the localization algorithm,?
4. If a VBF scenario runs (a) with and (b) without the localization algorithm, then theoretically, the overall performance of VBF in the case 'a' ( with localization) will be a little bit poor than that of 'b' (with localization) - because, localization will only provide approximate, estimated location but ns-3 will provide ideal, exact locations. - am I correct?
5. Is the present implementation of range-based and range-free localization algorithms could be used in a UWSN simulation?
6. Further, the in the helper functions, the time synchronization and localization-related lines are commented.
   //Ptr sync = m_sync.Create();
   //Ptr loc = m_localization.Create();
   //device->SetMac(mac,sync,loc);
   should we uncomment those lines to make use of localization?

Of course, it may be possible to use localization features on a trial-and-error basis. But, your answers may help one to use them in a correct, authentic way.

CTSTimer is not working

In fama.cc , CTSTimer is not working.
I set delay for timer, but it does not work.
how can i fix it?

Double Header Lines Appear in Trace file

Hi, When run DBR with trace on we have noticed occasionally that in different transmission and receiving events there are multiple of a single header type. Specifically we have seen duplicates aqua-sim header and DBR header (different information within each). What maybe the cause of this and what does it mean?

Thanks and hope to hear from you soon.

Saving pcap file

I would like to save the pcap file for the ddos.cc script. Currently, it is not present. Could you kindly help me capture the pcap file?

Transmission range

Is there a transmission range between the nodes? If so, what is the transmission range? Can I set it?

No result when running examples

When I studied to run Aqua-Sim Next Generation. I can`t see any packet or any simulation results. It just show "fin". Is there some code I need to add or change in the example?
