[Contiki-developers] performance of runicast

[ali j. <ali...@go...>]

Hi list,
I am using runicast as well as unicast in my program. I have observed that
when I use runicast the number of messages delivered to the sink becomes
less than when I use simple unicast. I don't receive any message if I set
MAX_RETRANSMISSIONS to 1. should it always be set to a value of 2 or higher?
I don't see much improvement or no improvement at all at times when I
increase MAX_RETRANSMISSIONS to values like 4, 5, 6 etc. The other runicast
parameter NUM_HISTORY_ENTRIES doesn't make much difference either. If
someone has also evaluated the performance of runicast and has observed
similar behavior, please help me figure out the reasons of this strange
behavior. I am using contiki-2.4.

Best Regards,
