Re: [ns] Transmit packets
Hi all I have another question with the control of packet transmission. Like I said before, I want to transmit my packets in a time interval (let's call it send interval), but let's suppose that the current time of the simulator is out of that interval (so no packets have to be transmitted). I'd like my routing protocol enque those packets which may be send in the following send interval. I do not know exactly what to do. I suppose that I have to create a queue (i.e. using the class Priqueue), or are there any other form? And I suppose that in the recv method of my routing protocol I may put the code to enque and deque packets... (Another thing, I forgot to say that I'm using IEEE 802.15.4) Please, I need help with that, I know a lot of things, but I'm not what to do!!

Explanation: In your tcl script, you will assign routing agent (ragent_) to all the nodes and this routing agent will help you to write your own procedure in the Command of your routing protocol. Then, once you are in the Command of the routing protocol, you will use timers. This timer will expire on the predefine time, which you can mention there and then you can write your packet sending logic there. E.g. you want to send all the nodes to send packet after 10 secs. The timer will expire after 10 secs and send the packets http://old.nabble.com/Reply-to-ragent_-question-td18590880.html#a18590880 http://old.nabble.com/Example-of-Simple-Timer-td19366929.html#a19366929 Hope it helps Best Regards Mubashir Husain Rehmani Lip6/UPMC Sorbonne Universités Paris, France On 7 December 2010 14:02, David Rodenas drodenasherr...@yahoo.es wrote: Hi all I have to questions: How can I control the transmission of packets?

[ns] UMTS-WIFI Handover using NIST module - Resolved
Hi,
Do you find a solution to include movement in umts interface using NIST module ?
I know that it's possible to add movement to iface80211 and iface80216 but not
yet for umts ?
Concerning the data trafic that ifaceUMTS never receive .. you should add this
in your TCL code
# control for umts interface##
set node_odd [expr $nn % 2] ; nn is the number of mobile
if { $node_odd == 1 } {
set dummy_node [$ns create-Umtsnode 0.0.[expr 2+$nn]]
puts *** dummy: tcl=$dummy_node; id=[$dummy_node id]; addr=[$dummy_node
node-addr]
}
# don't ask me why we should have a pair number of umts interfaces :)
then, to see the trafic in the tracefile , you should add these lines:
$bsUMTS trace-outlink $f 2
$iface0_($j) trace-inlink $f 2 ;# for each umts interface that u create
$iface0_($j) trace-outlink $f 3 ;# for each umts interface that u create
