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:

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.

It's my first app for android, and i have problem with applicationContext in runnable class. I want to make a server in kotlin (or java), but when i try to do it, a can't use applicationContext (when i use it in "override fun onCreate" all is ok. It's my class:

This is my PowerShell which is calling an API and returning a JSON response.

Not used powershell much so please forgive me. I have an API request which returns JSON that I need to turn into a CSV or xlsx file.

I have the following dictionary

d={'s1': {'s2': {}, 's3': {}, 's4': {}}, 's2': {'s5': {'bw': 20, 'delay': '1ms'}}, 's3': {'s6': {'bw': 20, 'delay': '1ms'}}, 's4': {'s7': {'bw': 20, 'delay': '1ms'}}, 's5': {'h1': {'bw': 10, 'delay': '5ms'}, 'h2': {'bw': 10, 'delay': '5ms'}}, 's6': {'h3': {'bw': 10, 'delay': '5ms'}, 'h4': {'bw': 10, 'delay': '5ms'}}, 's7': {'h5': {'bw': 10, 'delay': '5ms'}, 'h6': {'bw': 10, 'delay': '5ms'}}}

I would like to access the values of bw and delay for link. For ex- I want addLink(s7,h6,bw=10,delay=5ms) to work.

I am using following code for it #!/usr/bin/python
