1. I designed a new routing protocol and had integrated it inside AquaSim. Documents about what changes to do in Tcl can be found easily. And I also designed a new UWSink. So what changes do I need to do in Tcl files? I cannot find any documents about this.
Dear All, I want to schedule transmissions between sensor nodes and sinks in UWSNs. Suppose there are 100 sensor nodes and 2 sinks, the result the first 50 nodes will send to sink1 and the second 50 nodes send to sink2. by default the transmission range in aqua-sim is the same for all nodes. so i need to change the transmission range for each node based on distance between node and its sink. So, how do I change the transmission range for each node? Thank you in advance.
Since Aqua-Sim 1.0 is only using a single channel model, I don't believe there is anyway to hard code a unique range per node on the channel (assigning distCST_ to a direct value). While you may be able to use the TxPower on each node's phy layer to uniquely handle transmission range (since dependent on the sink's receiving threshold a given packet may be non-decodable and therefore dropped by the sink).
I'm trying to study transport protocols in underwater wireless sensor with aquasim, but I cannot see where its locate!!!!
I see the Mac ptorocol , Routing protocol but no folder for transport protocol !!! Can you please explain me more? is there any transport protocol in aquasin ?

I am using setdest to move my node. After setting destination, I am sending packets to the node at that location, but it's not receiving. The receiver and sender nodes are adjacent to each other , still its not receiving. I am using VBF and broadcast MAC. Does anybody know why?
I am studying VBF, in which there is a Sink initiated query concept in which we can have location dependent query; To serve this purpose, if I'm nt wrong, we are provided with "announce" command that calls bcast_interest method. Now, when I call announce , no node receives the packet, Why is that so?
In my simulation scenarios, I am sending some packets from node 0. According to trace file being generated, the packet is being received by 4 other nodes, but when I terminate agents for those nodes. For my target node it displays 1 received but for other 3 nodes, it shows 0(zero) packets received at console. Why does that mean?
Please let me know which tcl code you are running. (Is it your own or some example code?)

Dear Ms Jalaja, yeah it's my own, Actually, I am using VBF but I've disabled Routing, so what I think is they might be receiving packets as forwarder nodes; but I 'm nt sure if this is what's happening. What do u think?

I am counting packets using a variable in .cc file. Now, I want to get that value in my .tcl script, store it in some variable and perform some operation on it? How is that possible?
Is there any way to perform a specific function on the packet received by the sink while simulating not from trace file. For example, Sink receives a TCP packet , now I want it(sink) to extract the node id from the packet and save it and perform some function on it. So, is it possible with Aqua-Sim ??
Yes, you can do it in Aqua-Sim. What you need is to modify the corresponding .cc source file and recompile the package. As long as the information is included in the packet header, you will be able to read it, save it to the file or do any operation you like. If the information you need is not included in the header of any layers, you can add it to the appropriate layer (MAC, Routing or TCP) by modifying the .h file.
How to define the packet headers?please anyone help

NS2's documentation on packet headers can be found here <http://www.isi.edu/nsnam/ns/doc/node127.html>. Beyond this I would recommend reviewing current Aqua-Sim protocols, such as broadcastMAC, to gather a stronger understanding of how they are accessed and used. Additionally, reference packet header file to review some of the basic principles of hdr_cmn.

hi, I have some questions about aqua-sim,can anyone help me ? 1. In file underwaterpropagation.cc, there are no ambient nosie parameters? 2. If i want to change the communication range, I can just change the Pt_ and RXThresh? 3. In the paper 'An NS-2 Based Simulator for Underwater Sensor Netwotks', the author say that 'Aqua-Sim provides users two ways to determine the transmission range: one way is to set the transmission power and the threshold of received power level; and the other way is to set the transmission range directly.' but I have not found the second way. Although the
You are right. You cant change the transmission range from the TCL file because it is set to a default value in the underwaterpropagation.cc. You will find the following command in the beginning of underwaterchannel.cc.
double UnderwaterChannel::distCST_ =1150.0;
It need not be 1150 in your version of Aqua-Sim, still the value given here is the transmission range used. So, if you want to change the transmission range, change it in underwaterchannel.cc. Please dont forget to compile it once you have modified the .cc file (make clean, make, make install).
I'm running a simulation and getting the following error:
Missing required flag -x in: W -t 150 Missing required flag -y in: W -t 150 Parsing error in event. What exactly is leading to this error and how can I resolve it?
Kindly let me know if there is some proper tutorials or documentation or some reference manual (for commands) available, for Aqua-Sim other than that are available on "http://obinet.engr.uconn.edu/wiki/index.php/Aqua-Sim" . I am new to Aqua-Sim and facing lot of problems. Thank you!
The current support for mobility on Aqua-Sim is limited to the few protocols currently in place. To my knowledge these protocols allow the user to set min/max speeds but not the destination from a TCL script. However, you may hard code the destination within the c++ section of the mobility pattern being used to support your testing.

If I recall correctly, localization strategies are not strongly implemented in the current version of Aqua-Sim. This is an area of future work for the simulator. Instead you may need to emulate some form of underwater localization yourself, like the follow: uwsn localization <http://www.cse.uconn.edu/~jcui/UWSN_papers/UbiNet-TR06-04_localization.pdf> .

Dear Sir Please suggest a propagation model (supported by aquasim) that i could use for my underwater sensor network simulation.
For terrestrial networks we using Radio propagation model (TwoRayGround) which won't work for underwater acoustic channel.set val(prop) Propagation/TwoRayGround;
Aqua-Sim currently supports Rayleigh Attenuation seen in uw_mac/underwaterpropagation.h. Future plans to extend supported propagation models are in works for the next iteration of Aqua-Sim.

When a packet is collided, HDR_CMN(pkt)->error() will return a non-zero number, which is most likely 1. However, please be cautious that when an error packet reception is caused due to low transmission power (long distance), HDR_CMN(pkt) ->error() could also return a non-zero value. If you need, you can do some minor modifications in underwatermac.cc to differentiate two cases.

I'm not an expert in error correction coding. So I did some research on implementing it in NS2. Hope my information can help.
From my knowledge, there are two options to implement error correction coding in Aqua-Sim.
1. Implement the bit error rate model of the interested coding scheme in Aqua-Sim. The model will simulate the performance of the coding scheme in terms of bit error rate or packet error rate, so that you can incorporate coding into Aqua-Sim.
I am trying to implement Reed Solomon coding in underwater acoustic sensor network which is in the packet level. Whether it is possible to do that in Aquasim? If so what modifications i have to do? Writing a code in cpp will be sufficient? Any idea?

hi, I am facing the following problem during installation of Aqua Sim. make: *** [tkEntry.o] Error 5 tk8.4.13 make failed! Exiting . please help me to solve this problem.
I am very new to aquasim. I have installed it successfully. I have tried going through the web for any documentation for aqausim that will get me started. I found very good reference and a user tutorial at http://obinet.engr.uconn.edu/wiki/index.php/Aqua-Sim . I wanted to know if there is any other documentation for users, that can help me write a fully functional script. I am also unfamiliar with ns-2. So, should I read up ns-2 documentation first ?
Can anyone tell me the use of cx,cy,cz parameters in a UWsink agent ??
Thanks

Thanks for the reply. Can u tell me how is cx,cy,cz different from X_,Y_,Z_ ? How are they related ?
Thanks

I was going through NS-2 and aquasim. I found out that NS-2 has its default routing as static routing and it need not be specified in the node specifications. Is the default routing method for UWSN, VBF ? Do we have to use VBF in all network configurations in UWSN, even though there is no need for routing in the scenario(like two nodes sending data to each other)
Can somebody tell me what is the meaning of "too many backoffs" and how to avoid it so ensure a very good packet delivery ratio.
Thanks

Guess you are using broadcast Mac. Which routing protocol do you use? On Mar 4, 2014 9:04 AM, "souvik dutta" <[log in to unmask]> wrote:

I read the paper on VBF by Xie et al. But while writing a script do we really need to specify cx,cy,cz if it is as said in the paper.

You are right, I have been using broadcast MAC. What is the problem ? I am very new to aquasim

That backoff is part of the broadcast MAC. Whenever a node tries to send out a packet, it backs off if its modem is busy. If this happens too many time, it reports 'to many backoffs' and drops that packet. Due to the broadcast feature of VBF, it can only work with broadcast MAC.
Thanks a lot for the explanation. I will try GOAL. While using broadcast MAC itself I also noticed that if I change the position of nodes a bit. The backoffs reduce significantly. Can you say what might be the reason
thanks

That could be, because neighboring nodes could affect each others. If a node is receiving or overhearing, it has to backoff in this broadcast mac implementation.
You can find documents on Aqua-Sim wiki page. You can find aqua-sim user manual and developer manual. Since you know NS-2 already, Aqua-Sim should be easy for you. Just remember to check the source code, especially command() method of those protocols, then you would know their usages.
Is GOAL available with the current version of Aqua-Sim? If not, how to get its source code?

Thanks a lot for the paper. I have read the paper on VBF and understand it to a fair degree, but while implementing it in aquasim I don't get the meaning of the variables cx, cy, cz. For example,
set node_(2) [$ns_ node 2] $node_(2) set sinkStatus_ 1 $god_ new_node $node_(2) $node_(2) set X_ 20 $node_(2) set Y_ -20 $node_(2) set Z_ 0 $node_(2) set-cx 20 $node_(2) set-cy -20 $node_(2) set-cz 0
Can someone tell me the units of time and distance used in aquasim ? Is it seconds and meters respectively ?
Thanks

Hello, I would like to know the exact structure and description of the queries exchanged by the VBF routing protocol such as: INTEREST, DATA, DATA_READY,DATA_DISCOVERY, SOURCE_DISCOVERY , SOURCE_TIMEOUT, TARGET_DISCOVERY, TARGET_REQUEST, SOURCE_DENY I can't find a detailed information
Thanks a lot for the email and I appreciate your time.
1. I have also come across those links you shared which provided an overview of the protocols in Aqua-Sim, however not in details. Moreover, i have been thoroughly reviewing the codebase to have a grasp of the logic behind the Dynamic routing protocol
Unfortunately it has been years since I have worked on Aqua-Sim NG and anything related to UWSNs so my knowledge will be lacking but I will try my best to answer your questions.
1. To assist in Aqua-Sim NG being spatially aware it most likely resembles a distance vector protocol. While this can of course be expanded within the code this is what was originally designed in earlier versions of Aqua-Sim (1.0) and therefore is slightly outside of my scope. https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fieeexplore.ieee.org%2Fdocument%2F5422081&data=04%7C01%7CAQUASIM-L%40listserv.uconn.edu%7Cca1001e8aa9e4846475d08d86de93d55%7C17f1a87e2a254eaab9df9d439034b080%7C0%7C0%7C637380195805087531%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=bollsCuPWL9hpjQDopSBuh60Iq9%2BiS2cxAPYfzo13EI%3D&reserved=0 may be a good jumping off point for
Trust the day is going well. In reference to the above subject, as part of my MSc research project, i plan to implement Channel-aware routing protocol applicable to the Underwater Acoustic (UAN) channel which has necessitated the need to review a number of routing modules in Aqua-Sim cognizant of the high fidelity it has proven for the UAN channel.
Dear All, I've created a code for AquaSIM-NG to send a packet from one node to another. The code seems to be completely alright, Bt packet is nt being send. I've attached my file, please have a look and kindly let me know the issue. Thank yo u.
Dear all, I am using* "AquaSim- NG"* and having issues applying aqua sim energy model to my application scenario. Please send me a sample script that demonstrate use of *"aqua-sim-energy-model.h"* and calculate energy consumption of each node. Thank you.

Trust the day is going well and thanks for the other day. I am trying to leverage callbacks in Aqua-Sim-NG to obtain metrics for performance evaluation such as: Packet Success Ratio, Throughput efficiency etc. The config path for the received packet callback has been difficult to obtain even after going through a number of documentations. Below shows what i have which is not correct as it returns an error while compiling:
