Energy Harvesting doesn't work with RPL protocol

[khabid]

Dear Mr Victor,
I tried to add some code to the opt_sched_test but this way the energy harvesting process doesn't work correctly. It doesn't print harvested energy and add it to the battery.
Please help, I'm blocked here for one month.
Thank you

Hi @khabid ,

Sorry for the delay.
First, with regards to using RPL and the energy harvesting I think the problem might be that when RPL is enabled the IP stack is used. This in turn takes control over the uart that is used to communicate EH values over the serial sockets from Cooja.

Can you check your contiki-sky-main.c and look for uart1_set_input... followed by serial_line_init...? They should be surrounded by a pre-processor conditional for IPv4 or IPv6 NETSTACK. Try to remove that conditional (or you can replace it with your own macro if you want). I think that this will break the RPL border router because it uses the same uart to communicate over the serial line (SLIP). But you shouldn't need EH on the border router anyway.

For the changes made to opt_sched_test, can you please paste them in your message so I can check?

Regards,
Victor

Dear Mr Victor,
I am trying to work with the code given by you. I have paste the folder eh_contiki under Home folder. But when I am going to run the file optsched_test.c file I am getting the Makefile error. How to avoid that. I think I have done some basic error. Where to put the folder exactly. Can you please guide me?
Thank you

Hi @somnathmid ,

Did you set the CONTIKI variable in the Makefile? You must set it to the path to your Contiki installation.

Regards,
Victor

Thank You very much that you have replied to me I will set and check, May be after that also I need your help Thanks Somnath Sinha

[somnathmid]

Sir I failed to run your code. Can you tell me where exactly I have t keep the folder eh_contiki-master so that path related error will not come Thanks Somnath Sinha

[somnathmid]

If I run the .csc file directly I am getting some error which I have attached Thanks Somnath Sinha

[somnathmid]

I have uploaded the folder directly under HOME. What to do ?

[somnathmid]

Now code is running optsched_test.c is running but fatal error is coming eh_sim.h no such file it is telling

[somnathmid]

Now I am getting some error in function calling Somnath Sinha

[somnathmid]

I am getting this error

[somnathmid]

When i run directly the .csc file I am getting this

[somnathmid]

I change the Make file lke this and put all all the folder from app to the core folder

[somnathmid]

Change the .c file by changing the path of header file

[somnathmid]

Sir, I am waiting for your suggestions

[somnathmid]

Undefined reference it is showing

[victorcionca]

Hi @somnathmid
Can you please compile the example straight in the command line and share the log of the compilation?
Don't forget to clean first so any objects left from previous attempts are cleaned.
Also:

• what Contiki are you running? legacy or NG? This was developed on legacy so I'm not sure if it works on NG
• what is the path to your Contiki folder?
• what is the path to this repository (that includes the apps and examples folders)?

Thanks,
Victor

[somnathmid]

I am using InstantContiki2.7

[somnathmid]

I think the path you can understand now, Thanks, waiting for suggestions

[somnathmid]

Hi, Your code is running, Thanks a lot I got sum result

[somnathmid]

But I am not able t run .py file . How to do that ?

[victorcionca]

Hi @somnathmid
Based on the screenshots above it looks like you've copied the apps and examples folders straight into the contiki folder, which should be fine. However, you still have to configure the CONTIKI variable in the Makefile, which it looks like you haven't done, based on the two screenshots. CONTIKI should be "../.."

You say you got some results. The python energy source simulator should be started before you run the CSC.
How did you run it and what error did you get. Did you follow the instructions in the README file of the python tool?

[somnathmid]

I am getting this after executing the command. What to do ?

[somnathmid]

Java stack trace error is coming

[somnathmid]

.csc file is running but from python eh_source_server.py <shader.pickle> i am not getting change

[somnathmid]

How to get EH can you please guide

[somnathmid]

Some new errors are coming while executing test.csc

[somnathmid]

How to start python energy source simulator

[somnathmid]

[somnathmid]

Am I getting the output rightly ?

[somnathmid]

Only I am getting this, I don't know may be due to server connevtivity

[victorcionca]

Hi @somnathmid

You need to use a trace of harvested energy data.
I just uploaded one in the "sim_eh_source" folder, it is called "columbia_irr_only_no_gaps.csv".
I also uploaded a shader file. This adds shadows onto the deployment area

You must run the eh_source_server.py as follows:
python eh_source_server.py 60000 columbia_irr_only_no_gaps.csv 0 test_shaders.pickle

You can drop the test_shaders.pickle from the command line in which case the shadows will be randomly generated.

First run the python script and then run the Cooja CSC file. When Cooja starts the python script will connect to the Cooja serial sockets that are defined in the CSC (with the TCP port numbers starting at 60000, if you haven't modified their values).

In the Cooja log you should periodically see, for each node, "Harvested X", which means that the node harvested some energy.

Let me know how it works.

Best regards,
Victor

Thank you, i will check and inform Somnath Sinha
