[ns] Fwd: pure ALOHA Mac Protocol for wireless ??
Hi all, I have to implement an pure aloha mac protocol for my wireless comunication in ns2. I work with the NRLSensorSim extensions for sensor networks and ns-allinone-2.27. Someones know if it comes implemented in ns2??? In ns/mac there are: mac-802_11.cc, mac-802_3.cc, mac.cc, mac-csma.cc, mac-multihop.cc, mac-simple.cc, mac-tdma.cc, mac-timers.cc, smac.cc Is one of those who implement the aloha ??? What about mac-simple ??? and mac ?? Thank you

[ns] [AODV] Interface Queue and AODV packet queue
Hello everyone, I am doing project regarding to monitor each node's packet queue length in AODV. However, there are two queue lengths in ns2 src code that makes me confused. The `interface queue length` and the `Drop-front queue` in AODV src file aodv_rqueue.cc. If I want to get the packet queue length of each node during simulations, should I get the length of the interface queue or the length in aodv_rqueue.cc ? interface queue length or rqueue.len_ ?? Regards, Martin
[ns] Run dsRED with routing protocol!!! Could anyone help me ???
I read your post on the ns-2 mailing list. I practice DiffServ on ns-2 and I met your problem that make DiffServ compatible with routing protocol. For example, 5 Mb |s1|- 5 ms 10 Mb \ |core2||core3| 5 ms \/ 10 Mb \ 10 Mb 5 ms \ /5 ms \ |e1|---|core|--|e2|---|dest| /10 Mb5 Mb 10 Mb / 5 ms5 ms5 ms / |s2|- 10 Mb 5 ms e1, core, core2, core3, e2 are belong to DiffServ network. s1, s2 send packets to dest. dsRed module doesn't support routing protocol, so when setting routing protocol, the error happens, And if don't setting routing protocol, the error happens also because e1 doesn't know where it forward packets to. Could anyone help me to resolve it ??? Thank you very much I'm looking forward to your soonest response.

[ns] Calculating Average End-to-End Delay is slow with awk
Hi everyone, When you all calculating the average End-to-End delay for a particular simulation, do you take all of the recv entries? (that is if there is 2 receives, you will gather all 2 to calculate the average) However, the number of receives packets is very large ~19 at some stage and the calculation time of the end-to-end delay take ages. I'm using awk to calculate the average delay and at the moment I only take few thousands of recv entries from my trace file. (Which I think its not very accurate.) So do anyone of you know a better way to calculate the average delay fast with all the recv entries? Thanks in advance Regards, Martin

[ns] Problem with MAC 802.11 in NIST model
Hi all!,
I've just found a possible error in MAC 802.11 in NIST model. The handovers
didn't finish correctly, so I found a possible missing step in the handover
process.
When we create the mobile nodes in TCL scripts, in the NIST examples we use
the command:
$node ($i) base-station [AddreParams addr2if [$bstation1 node-addr]];
in order to get the mobile-node will be connected to a initial basestation.
This command call the set_base_stn(addr) { base_stn_ = addr} method definde
in mobilenode.h.
The problem comes when the mobile node want to be attached with another base
station.
This command is never executed again for new basestation, so I've coded this
by myself to execute it after Association negotiation:
MobileNode *node_ = (MobileNode *)
Node::get_node_by_id(netif_-node()-nodeid());
if (node_ != NULL){
MobileNode *bs_ = (MobileNode *) Node::get_node_by_id(src);
if (bs_!= NULL) {
node_-set_base_stn(bs_-address());
}
}
The problem here is in this line:
MobileNode *bs_ = (MobileNode *) Node::get_node_by_id(src);
get_node_by_id(src) waits for an node ID, not a MAC ID (they aren't the
same). src it the basestation mac id, so the question is: How to get the
basestation node ID??? (this code is in the mobile node mac instance, so no
problem to get mobile node ID from the Mobile node mac id:
netif_-node()-nodeid()))
In order to avoid this problems I assign to the MAC ID the same ID from the
node where it is, so get_node_by_id(src) returns the good one.
Is this a bug??
I hope I have explained my problem in a understandable way. I tried to do
that as crearly as I could.
Best regards and thanks for your help.

[ns] How to simulate a smurf attack?
Dear all,Later I want to simulate a smurf attack and there are two
problems.(1)The attack node send a ping packet what's source address is
other node's.So it is forgerying IP address. (2)Can a Agent connect mang
Agent?There is a wrong when I do it.Such as:ping start-WL-brdcast,
and then,--- Classfier::no-slot{} default handler (tcl渂/ns-lib.tcl) ---
