Re: [Contiki-developers] performance of runicast

[Borms, J. <jb...@et...>]

Hello Ali,

"Performance" is very ambiguous and can mean many things (energy, throughput, delay, (re)transmission count, ...) some of which contradict in certain cases.

Could you explain your experimental setting in more detail?

Regards,
Joris

Subject: [Contiki-developers] performance of runicast

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,
