QUESTION
I am new to this domain of UnetStack and would appreciate help from the experts.
I have created a small network of 4 nodes. I am trying to connect my client node, e.g. node B, to the server node (A). I tried the communication between them through the shell. I was successful in it. But I am facing errors when I tried the same through agents. Basically, my client agent holds socket code for the client and the same case is for my server. My aim is to make fully functional communication between client and server nodes.
I created a server agent, and the client agent added those agents to the respective stacks of nodes. In the above-mentioned agents, I tried to implement my server socket code and client socket code in the respective agent's .groovy file. The server agent is added in the setup file named setup1.groovy while the Client agent is added in the setup2.groovy. The path to these respective files is mentioned in the respective node's stack section in the simulation script. But still, I am facing the following error:

QUESTION
I am writing a simulation script which involves 2-UUV and 1-USV. Both Underwater vehicle doing surveying in orthogonal lawnmower motion model. I would like to stay in the range of both vehicle, so they started at the same origin point. I want to know that How can define USV motion model in such a way that it is always in the communication range of both UUV's for most of the time.
- Basically How can I manually provide dynamic path planning/ motion model to
USVso that I can communicate to bothUUVmost of the time ? Is it even possible ? Could someone provide a basic example of this or point me in the right direction ?
Here is my simulation script :
...ANSWER
Answered 2021-Apr-26 at 07:55The Unet simulator supports multiple levels of motion models depending on the required complexity in the simulation.
The NodeInfo agent in each simulated node implements a basic dynamics model. The model is turned on using the mobility flag which can be set in a simulation script or directly on the NodeInfo agent. When mobility is enabled, the agent automatically updates location based on motion parameters such as speed and heading using the simple dynamics model. This can be handy to simulate the motion of a node, for example, an AUV swimming away from an underwater modem.
We can easily do this by manually updating the parameters of one of the nodes in a simulation. Use the 2-node-network example from Unet IDE. The "Map" view of the IDE is handy to visualize the motion of nodes. Connect to the WebShell of Node A and set the mobility, heading, and speed parameters. As the simulation continues the location of Node A will continue to be updated based on the speed and heading.
QUESTION
I have a data frame with the following sample data:
I need to a new column (I've used add_column) "CAGE_LOCATION". The new values need to be based on conditions/rules for the Bldg and Bldg-Room as follows:
- Bldg 5A = 1
- Bldg 62 = 2
- Bldg 62-A = 4
- Bldg ARL = 5
- Bldg-Room 53C-106 = 6
- Bldg-Room 5A-147 = 7
- Bldg-Room 5A-157 = 7
All other Bldg = 3.
Desired outcome should be as below:
I have tried a merge using a Location dataframe and also ifelse statements. But only part of the list gets correct value.

...ANSWER
Answered 2021-Apr-09 at 20:03You'll want to create a lookup table and then join it to each of the two match columns of your data. Then you can replace any missing values with 3.
First, let's create a reproducible dataframe in the same format as your data. I use "OTHER LOCATION" to make it obvious where we don't expect a match in a given column.

I have implemented a localization algorithm with 4 nodes topology and it is working fine but in the log file I am getting this error and I am not able to understand where the problem is. The algorithm gets stuck for sometime and this error appears and after that it again resumes the normal flow.how to remove this error ?
...ANSWER
Answered 2021-Apr-01 at 17:06I ran your simulation using the code you provided and managed to reproduce the error. Tracing through the logs, I found that the error occurred on the third motion update for node B, whereas your simulation script only seemed to have 2 legs in the motion model. That gave me a hint as to what the problem was.

Answered 2021-Mar-31 at 16:13If I correctly understood what you want is basic python tx.py and rx.py which communicate in both real and simulation environment. Then answer is yes.

QUESTION
took the code from the one other forum. This code makes resizeble rectangles. I corrected a little for displaying pictures. if anyone knows, tell me how to calculate the position of the MovableCircle so that the initial aspect ratio is preserved.
I've implemented part of the algorithm for eBottomRight and eTopLeft, but it still works very bad and doesn't work for BottomLeft and TopRight points. I want that it will be look like Krita or PureRef resize behaviour.
Thanks for any help, regards max

QUESTION
I followed the tutorial here to create a static enum
For a domain value EXAMPLE, I would verbalise it to 'Example' and manually define the Getter (in ARL) as return "Example"; as explained in the tutorial.
Then I define an input/output variable myDomainExample and try testing it through the REST API.
If I write a dummy rule such as:

Answered 2021-Feb-16 at 17:52I found the problem, I mistakenly used 2 superclasses when defining this (Object and Enum).
Using only one (Object, as defined in the linked tutorial) solved the problem
QUESTION
I am trying to get coordinates from the neighbouring nodes using a broadcast request and store them into lists. I am able to get only one of the responses and I think this happened because of collision between the responses as the nodes have responded at the same time. I have tried to use the Backoff Behavior with random backoff on the agent of neighbouring node but it didn't solved the problem. How can I sync the mechanism to avoid the collision ? I have written an agent for each blind node (which will make the broadcast request) and the neighbouring nodes.
Following are the code snippets.
Agent on blind node:
...ANSWER
Answered 2021-Feb-13 at 14:35I've simplified your agents and made a working example. The anchor discovery is broken into 2 phases: (1) to find what anchors are around, and (2) get their locations. The reason to break it up is that you want the initial discovery to require minimum channel access to reduce chance of collisions. The later location request can be better controlled once you know what nodes are around.
I have combined the agents into a single simulation script, so you can simply copy the code in a file and run it:

I am trying to run this example from ARL py Tools documentation for generating
Barlett Beampattern which mentions usage of arlpy.bf.steering(); but when I try to run it says steering() not found.
ANSWER
Answered 2021-Feb-08 at 13:53This has been resolved now, as it seems that it arlpy.bf.steering() stayed from the pervious version which is now outdated and it will be updated to arlpy.bf.steering_plane_wave() in the next release.

I have been using this below code to get the Unique sorted value from Sheet1.Range("C4:C") and to paste into Sheet2.Range("C4"). This is working fine
But now i want use the same code to get the Unique sorted value from Sheet3.Range("C4:C") and to paste into Sheet2.Range("G4").
now the problem is that how to mention the Sheet reference in code that which sheet range unique sorted value will be paste.
Standard Module (e.g. Module1)
