The per node rate you can send at depends on the number of nodes in your topology (and the interference graph). For a 20 node topology (with around 3-4 hops) and packet size of 40 bytes (payload+header) without aggregation you should be able to hit around 2 packets per second. The average link quality also makes a difference. The average link quality for these topologies is around 40-50%.
For 40 node topology the numbers might come down to approximately 1 packet per second. These numbers should hold for CTP with CBR traffic. -Avinash On Thu, Mar 5, 2009 at 2:05 PM, Omprakash Gnawali <[email protected]> wrote: > On Wed, Mar 4, 2009 at 11:58 PM, Martin van de Goor > <[email protected]> wrote: > ... >>>> In my setup, five (regular) packets are sent each second by one node. >>>> These five packets are received by other nodes, aggregated into one >>>> packet at each node, and sent using CTP. >>>> The reason is that sometimes a node crashes and I'm trying to figure >>>> out whether it is my code or CTP not being suited for this purpose. > > 1 pkt/second with five nodes is not high rate at all.
