Communication mechanisam in adhoc network?  
Currently i am constructing an adhoc among several QNX machines, probably with other Linux machines in near future. So 
what kind of mechanism i should use to realize wireless communication? Message passing or socket? Thank u.
RE: Communication mechanisam in adhoc network?  
Hi Alex:
	That completely depends upon you and you're application.  If you're
dealing strictly with QNX machines and have no need to communicate with
another OS, then using Transparent Distributed Processing (aka QNET or
message passing) provides you a lot of advantages in terms of versatility
and distributed processing capability.  This may require a bit more work in
that any services that require network distribution should be built as
resource managers, but provides a lot of flexibility in terms of how the
services are accessed.

I'd strongly recommend reading up on the system architecture and networking
guides in the documentation to get more information.

	Robert.

Thank u, Robert.

Learned about the resource manager a couple of days. A little confused.

My current project is actually to establish an adhoc wireless network among severa QNX targets to realize the autonomout
 formation control.
So the msg needed among them includes the position, command...

And i think it easy in this way instead of writing a resource manager:
I just started up the Qnet, wrote data to another machine via the wireless network with the write function specifying 
the location of the machine in the network. And this really worked.  
So how and why should i use the resource manager?

Thanks
Alex
