[ns] what are the modifications of TCP delayed ACK for the case d>2?
Hello all I want to delay more than 2 ACKs on the TCP receiver side to study the interaction of TCP new reno with the 802.11 MAC protocol in wireless multi-hop networks. How can I modify the ns source code for the case of delaying more than two ACKs for example up to 3 or 4 ACKs? If anybody has any example, document or ns source code or knows any helpful website, please help me. Regards, Farzaneh - Pinpoint customers who are looking for what you sell.
Re: [ns] shutting down link or node with wireless topology
You can try to set the coordinates of the nodes to large values.
$node set X_ 1
$node set Y_ 1
I haven't done this before, hope it works.

[ns] Help add-interface ns-2.30
hi all,
I am trying to implement ODMRP (Monarch extension ns-2.1b8) on
ns-2.30. I have ported the code of ns-2.1b8 to 2.29 My odmrp code is
complied fine. but when i am using the tcl script which is there with the
ns-2.1b8 for running the ODMRP on a particular scenerio the
error in the file is as:

[ns] problem: installing ns2 2.27 on FC-5
Dear All, I intend to intall pdns and for that purpose am installing/configuring ns2-2.27 on FC-5. When I run make I get a lot of errors in the SCTP.h, SCTP.cc, Queue.h and various other files. They seem like syntax errors, as they refer to destructors, invalid lvalues, and invalid (class) namespace specifiers. Is there any patch that I could use for ns2-2.27?

Re: [ns] shutting down link or node with wireless topology
Hi all,
Thank you for answering but i tried the
$ns_ at 60.0 "$node_(0) off"
command which gave me the segment fault error, i then added the
energymodel to the node and here's what i get when i try running the
simulation:
ns: _o17 reset-state:
(_o17 cmd line 1)
invoked from within
"_o17 cmd reset-state"
invoked from within
"catch "$self cmd $args" ret"
invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
(procedure "_o17" line 2)
(SplitObject unknown line 2)
invoked from within
"_o17 reset-state"
here is my nodeconfig in the Tcl script
$ns_ node-config -adhocRouting $val(adhocRouting) \
-llType $val(ll) \
-macType $val(mac) \
-ifqType $val(ifq) \
-ifqLen $val(ifqlen) \
-antType $val(ant) \
-propType $val(prop) \
-phyType $val(netif) \
-channel $chan_1_ \
-topoInstance $topo \
-agentTrace ON \
-routerTrace ON \
-macTrace OFF \
-energyModel EnergyModel \
-rxPower 0.3 \
-txPower 0.6 \
-initialEnergy 0.1
can anyone help me with this output ? and please could someone explain the
difference between the
$ns_ at 60.0 "$node_(0) off"
and
$ns_ rtmodel-at 60.0 down $node_(0)
is the 1st one only available when using an energy model? and how come the
second one has no effect on wireless nodes
PS: i am using a 802.11 model
any help would be greatly appreciated
