repeat process in mesh network？

[loris he]

In the mesh network, the sender uses trickle algorithm to control the repeat sending process, and at last the sender will send the message forever in a max interval at a handle. then my question is : does the other nodes repeat the message from the sender using trickle control logic for a specific times ,or just simplely repeat send serveral times in a constant interval（if so, what's the interval, I can't get it in the mesh sample code）？

I had the same thought as you. I'm currently simulating the algorithm as implemented by nordic in matlab/octave, and what i'm seeing is that the variable c never reaches the k-constant.

In the RFC6206, it says "At time t, Trickle transmits if and only if the counter c is less than the redundancy constant k.". When c never reaches k, trickle will always transmit.

This change in algorithm was intentional, as stated in the documentation: "When the interval hits this upper limit, it will stay there and the device will keep repeating the message over and over forever." [1]

Here you find some information on how to disable the infinite transmitting: github.com/.../100
