[ns] Executing TCL Commands in Time Sequence

[Osama Rehman]

Hello everyone,

I am trying to create a simulation scenario in which I want the TCL command
executed at "time T" to be dependent on the output of "time T - 1". e.g.

$ns_ at 27 src_node;# This calls *src_node *procedure that computes the
"SRC" variable.
$ns_ at 28 "$app($SRC) start_transmit";   # This calls *start_transmit
*procedure
in *app *agent while using the SRC value computed from src_node procedure.

The problem is that the first line is getting executed but returning the
value after the execution of the second line.

In my original program, I need to keep the time difference between the
execution of both lines very small, such 0.1 second.

I hope anyone has a suggestion to overcome this issue, with thanks.

Regards,
Osama Rehman

Wireless sensor networks (WSNs) are gaining significant interest from academia 
and industry. Multihop wireless networks are self-organizing, self-healing with 
cost-effective deployment and maintenance; yet a lot needs to be done in terms 
of efficient and robust solutions. This special issue is dedicated to consider 
the technical and theoretical applications and challenges of bio-inspired 
networking and communication in WSN. Potential topics include, but are not 
limited to: Adaptive security mechanismsScalable network 
architectureSelf-organizing systemsSelf-healing mechanismsEvolutionary 
algorithmsAnt colonization, swarm intelligence techniquesArtificial neural 
networks Artificial immune methodologies

[ns] inquiry about agent -> app comm if they are on same node

[Syed Mohammad Irteza]

Dear Users,

I was interested in knowing how I can invoke an application's functions,
from an agent which is not directly associated with that application, but
simply happens to coexist on the same node.

I was able to see that from the agent layer, I can navigate to another
agent on the same node, by way of the node_ object, and then the node_'s
collection of agents_, from which one can grasp a particular agent by using
its known port number (to which we attached the agent to). Obviously all of
this can be done from the OTcl layer, I was not able to do it from the C++
layer.

But I don't know how to get to the application layer, from an
non-associated agent.

Thanks & Regards,
IRTEZA
