Description:
Description of Problem:
I'm working with Mobile IP and using ns-2.30 , I´ve already
modified ns2.30, following this step by step:
Makefile.in add noah/noah.o \ to OBJ_CC and tcl/mobility/noah.tcl \ to
NS_TCL_LIB
noah/noah.{h,cc} add noah.h and noah.cc to a new subdirectory noah/
tcl/mobility/noah.tcladd noah.tcl to tcl/mobility/
tcl/lib/ns-lib.tcl.hline 191: add source ../mobility/noah.tcl
line 603ff: add
NOAH {
set ragent [$self create-noah-agent $node]
}
line 768ff: add
Simulator instproc create-noah-agent { node } {
# Create a noah routing agent for this node
set ragent [new Agent/NOAH]
## setup address (supports hier-addr) for noah agent
## and mobilenode
set addr [$node node-addr]
$ragent addr $addr
$ragent node $node
if [Simulator set mobile_ip_] {
$ragent port-dmux [$node demux]
}
$node addr $addr
$node set ragent_ $ragent
return $ragent
}
while I am trying to run the ns it will display that :
ns:[code omitted because of length]
:invalid command name Agent/NOAH
while executing
Agent/NOAH set sport_ o
this is what i got after running the ns.
please help.
Thanks,
Hamid

[ns] Wireless Scenario Generator for NS-2 using MATLAB GUI, Help for some Developments
Hi every body, I've implemented a simple scenario generator for wireless networks to make it easy to simulate wireless nets on NS-2. By the way it's almost customized and I want to develop it for a general field in wireless simulation. That was not so easy for me to compile some available open source scenario generators on windows OS so I made my own using MATLAB GUI environment. Also I've some problems with NS-Mapper software, for example it was not allowed to save settings or running the generator because some plug-ins was not available on my system. My S-Gen is so easy to work, using a very friendly simple environment and I'm trying to make it as friendly as NS-Mapper. So I want to know if you can help me to complete this generator deploy it for distribution as an easy to use Scenario Generator for NS-2 wireless simulation. You can download My_S_Gen source files following this link : http://mailman.isi.edu/mailman/options/ns-users/[EMAIL PROTECTED] Best regards. Hamid Shiri (Phoenix) Email : [EMAIL PROTECTED]

Hi, I am working on mobile ad-hoc networks and have to do performance analysis of Bluetooth scatternet/ad-hoc networks for which i have run simulations. I came across bluehoc, blueware (bluetooth adaptors to ns2) but can't find any reasonable support/documentation and hence not able to install. Also can't find any place to get code/example scripts for bluetooth tcl scripts for bluetree, bluenet .. I spend lot of time to find/configure environment but sounds like wastage.

Dear all, I m sorry if I give your time again . I have Two questions. Can you help me? 1- How Carrier Sensing(CS) works in below situation? Suppose node A sends a packet to Node B and Node B in transmission range of node A . Does Node B sense Node A after full reception of a packet or node B can sense activity of Node A During this transmission? 2- Suppose a packet trigger EIFS in SIFS duration of a Node. Does EIFS turn on related timer after Expiring SIFS or as soon as Recognizing error in FCS? I m appreciating that hear from you as soon as possible. Best Regards Hamid Reza __ Do You Yahoo!?

[ns] Need Some Changes on IEEE 802.11 Mac Layer.
Dear All, In ECS: an Enhanced Carrier Sensing Mechanism for Wireless Ad-hoc Networks Paper. Authors proposed we can select Best Value For EIFS Based on Frame Length. We know : RTS: 20 bytes, CTS: 14 bytes,ACK: 14 bytes. But Frame length CTS and ACK is Equal. Authors proposed we can increase CTS value to 17. 1- But,How can we do this change in NS2.27? On Next step: Based on Frame length we select a good Value for EIFS: Proposed Values : EIFS(RTS) = SIFS + TxTi m e (CTS ) ; EIFS(CTS)=SIFS+TxTime(Max-Data-Length) ; EIFS(Data)=SIFS+ TxTime(ACK ) ; EIFS(ACK) =DIFS ; EIFS(collisionorunknowntype) =StandardEIFS ; Example if we Receive a frame(it s size equal with 14 bytes)We can find out this frame is ACK Frame and Best Value for EIFS is DIFS. 2- Can you bring me or guide me How can i implement these condition statements?

The short PLCP header is transmitted using the 2 Mbps
in 802.11b .
But we can not transmit it on NS2.27 because we have
not PLCPHeaderRate in its Implementation.
Short Preamble:
Mac/802_11 set PreambleLength_ 72
Mac/802_11 set PLCPHeaderLength 48
Mac/802_11 set PLCPDataRate 1e6

Re: [ns] Relation Between CSThresh_, RXThresh_ , Distance, Pt_ and Reciever Sensivity in 802.11b
Dear All , I Read Many Comments on Archive and Ns Coding: I know that a Cross Over Paramete exist For differing Between Short and Long Distance Propagation Model on Using Two-RayGround Model. If Below of Cd Use Friis Equation but on higher than It uses Main Two-ray Ground Equation. The packet signal strength is compared against CSThresh_ and RxThresh_ of the physical interface. If the Pr CSThresh_ then the packet is dropped as noise. If RxThresh_ Pr CSThresh_ the packet will be marked as packet error prior to be passed to MAC layer and Set its (EIFS)--- . Is this true? In My idea CSThresh Equal with WLAN 802.11 b Reciever Sensivity.Because Interface sense packets(may be noisy). Is this True? But How Can I Calculate CSRange And RXrange For Node Positioning? On Threshold.cc file but it can tell me only Pr on special distance and distance be its input parameters. I need a program that I give my Reciever sencivity and pt_ to it and Return me CSRang and RXrange. Or I should use Two Ray Ground Equation for this issue. Best Regards Hamid Reza __ Do You Yahoo!?
