Re: [ns] Problem NOAH with wired cum wireless scenario
Yes, maybe, sorry but I am new in ns2 and I don't understand some
things. In any case, there is something I can't explain myself. Topology is
like this:
mando == core == base unimovilsoldado(0) , with === -> wired
, and -> wireless link
If I send paquets from mando to base, it works!, and if I send from base
to soldado(0), it works too, but if I send paquets from mando to soldado(0)
the error mentioned appears. Anyone could help me?. Thanks in advance!

[ns] Problem NOAH with wired cum wireless scenario
Hi all !,
I have ns-2 2.30 and I've installed recently NOAH protocol. After succesful
test in wireless simple scenario, I add a couple of wired nodes, resulting a
topology of two wired nodes, one base station node, and 4 wireless nodes (one
of them acts as a repeater that connects the rest of the wireless nodes and
base-station node). Problem comes when I send traffic form a wired node to a
wireless one, appearing this error:
--- Classfier::no-slot{} default handler (tcl/lib/ns-lib.tcl) ---

I'm with the same problem, using RTP and AODV or DSDV. If anyone could help us!!, and I need it for my final project :-S -- View this message in context: http://www.nabble.com/Creating-Relay-Station-tf3290784.html#a9156884 Sent from the ns-users mailing list archive at Nabble.com.
[ns] HELP: Base Station routing??
Hi everybody, Does anyone know where is the piece of code that choose between wired/wireless interface for routing packets in base stations??. I am working with DSDV, and I want base station sends a packet through its wireless domain although packet destination is from another domain. My topology is like: BS0 - wired - BS1 - wireless - BS2 - wired - BS3 And the problem becomes when BS1 (1.0.0) tries to send to BS3 (2.0.0), because as its wireless domain is different from packet destination domain, it sends it through its wired link to BS0, and then it sends back to BS1... making an infinite loop. I haver searched in dsdv/dsdv.cc, but it seems that when base station sends packets through wired links, it does not use this code. Any suggestion will be thankful. Thanks! -- View this message in context: http://www.nabble.com/HELP%3A-Base-Station-routing---tf2581706.html#a7196763 Sent from the ns-users mailing list archive at Nabble.com.
[ns] How to add a route in DSDV??
Hi, I am a new new user of NS2 and I am trying to simulate a wireless scenario using DSDV. My NS-2 is 2.29 version, and I want to know if it is possible to add static routes in some mobile-nodes. This would be one solution to my previous question here ["Problem with wired/wireless links"] I think. Thanks! -- View this message in context: http://www.nabble.com/How-to-add-a-route-in-DSDV---tf2538384.html#a7071892 Sent from the ns-users mailing list archive at Nabble.com.
[ns] Problem with wired/wireless links in NS-2 2.29
Hi!! I am trying to run this topology in ns-2 2.29: BS0 (0.0.0) BS3 (2.0.0) | |- - - wireless link | |- wired link | |BS Base Station Node BS1- - - - - -BS2 (1.0.0)(1.0.1) So, the problem is that, running DSDV, when BS0 sends packets to BS3 and viceversa, I think when BS1 (or BS2) see that receiver domain does not belong to its wireless domain, it returns packets through wired link... generating a forever loop (BS0->BS1->BS0->BS1...) till timeout is reached. If anyone could help me I'll be gratefull. Best regards. -- View this message in context: http://www.nabble.com/Problem-with-wired-wireless-links-in-NS-2-2.29-tf2517232.html#a7021021 Sent from the ns-users mailing list archive at Nabble.com.
