Re: [ns] how to print routing table
hi there , ok what i think you should do is to follow the codes i sent you earlier . You can make necessary changes in it like i did to print the packet numbs last time . Like now i print out the follwoing line . BLACK LISTED NODE: 0t 13.t 1t 0t 255t 0t 0t 0.t 0 BLACK LISTED NODE: 0t 19.t 1t 0t 255t 0t 0t 0.t 0 BLACK LISTED NODE: 2t 28.0059t 0t 0t 1t 14t 1t 38.0059t 38 BLACK LISTED NODE: 0t 31.t 2t 2t 1t 6t 1t 34.0012t 0 I just printed BLACK LISTED NODE and nothing else . No need for declaring a separate class for BLNs. It will make your work more difficult . The clue is to make changes in the code i told you . Its quite easy and obvious . you can do it . The clue is that you will print only the BLNs only in the rtable.txt but for that you have to identify them. I hope you understand my point . regards On Sun, Jan 22, 2012 at 10:58 AM, shanmugha priya balasubramanian < shanmughapri...@gmail.com> wrote: > sir, > > blacklist means t node in this list should not be allowed in network > (i.e) > as u say do not want them to be displayed later in your trace file. > > sir do i want to have a seperate blacklist class for maintaining > malicious nodes > > Awaiting ur reply > Shanmugha Priya > > On 1/22/12, shoaib saleem wrote: > > hello , > > > > By black list , what does that mean ? .

Re: [ns] getting values from trace file during execution of tcl script
Hello!
You don't need to pull the data from the trace file, you can get it from the
sender / receiver objects (like bytes_ variable in TCPSink and LossMonitor for
received bytes). You can also use ns "at" function to schedule the logging.
Here is an example for bytes received:
[code]
proc record {} {
global sink0
set ns [Simulator instance]
#Set the time after which the procedure should be called again
set time 0.5
#How many bytes have been received by the traffic sink?
set bw0 [$sink0 set bytes_]
#Get the current time
set now [$ns now]
#Output the current time and received bytes
puts "$now $bw0"
#You can reset bytes count to get only the bytes received from the previous log
($now-$time)
#If you exclude the following line you will get all the bytes that were
received from the simulation start up untill now
$sink0 set bytes_ 0
#Re-schedule the procedure
$ns at [expr $now+$time] "record"
}
#Start the record
$ns at 0.0 "record"
[/code]
(taken from some presentation and changed a bit, you can find these resources
online, search for "recording throughput in ns")
So you basically have a function that recursively schedules its execution.
Check the manual for the ways of getting the sent and received packets od the
agent you are using, it should work. I'm currently using this method to log the
used throughput of several TCP connections. I must admit, I have some
unexpected results, like I have a time period when more packets are transmitted
than a maximum throughput should allow. I must find the error.
Hope this helps.

[ns] CBQ/WRR for mobile nodes
Dear all ns-users i run some codes of cbq/wrr for wired networks, it run fine, but when i use it for wireless network and set IFQ as Queue/CBQ/WRR, simulation at once terminate without any result. how can i use cbq/wrr for wireless ad hoc networks Regards Moazzam

[ns] CFP-IST-AWSN, Ontario, Canada, August 27-29, 2012
Call For Papers (Apologies for multiple copies) Intelligent System Techniques for Ad hoc and Wireless Sensor Networks 2012 (IST-AWSN'12) will be held in conjunction with the 3rd International Conference on Ambient Systems, Networks and Technologies (ANT-2012) in Niagara Falls, Ontario, Canada, August 27-29, 2012. Recent developments of low-cost, low-power, multifunctional wireless sensors have enabled the fast growth of Wireless Sensor Network (WSN) applications, which include security, military, agriculture, automation, environmental and habitat monitoring. WSNs consist of numerous small inexpensive battery powered sensors; each sensor has the capability to process and store the sensor data. A combination of the dense deployment of numerous smart sensors, AI techniques, and intelligent agents can provide continuous real-time monitoring that is precise, accurate, reliable, and inexpensive. This symposium aims to bring together researchers and practitioners working on different aspects of wireless sensor networks and software agent technology in an effort to highlight the state-of-the-art and discuss the challenges and opportunities to explore new research directions. We strongly welcome submissions that include results which advance the state of the art relating to the theme of the symposium. The main topics to be addressed include (but not limited to): • Adaptive agents in AWSN • Agent security and trust in AWSNs • Agent-based architectures for AWSNs • Agents design issues dealing with reliability, efficiency, and fault tolerance • Context and situation awareness • Database management systems for AWSNs • Distributed management systems for AWSNs • Future Internet of Things • Intelligent data fusion and aggregation • Intelligent query and data dissemination • Intelligent systems for AWSNs • Learning agents in AWSN • M2M communication protocols for sensors networks • Middleware for sensors network • Mobile agents in AWSNs • Monitoring agents in AWSNs • Peer-to-Peer systems for AWSNs • Power management and energy-efficient protocols • QoS, performance evaluation and simulation • Routing protocols for AWSNs • Safe transmissions of data in AWSNs • Self-organization of AWSNs • Sensors and actuators infrastructures for ubiquitous robotics applications • Sensors Knowledge Modeling and reasoning with Uncertainty • Smart energy-efficient routing protocols Publication Only original papers will be considered that have neither been published nor submitted for publication elsewhere, including web publication. All submissions will be handled electronically. The length of the paper is limited to 6 pages. All papers will be reviewed by at least two independent reviewers. Accepted papers will be printed in the conference proceedings published by Elsevier Science in the open-access Procedia Computer Science series (on-line and CD). Procedia Computer Sciences is hosted on www.Elsevier.com and on Elsevier content platform ScienceDirect (www.sciencedirect.com), and will be freely available worldwide. All papers in Procedia will also be indexed by Scopus (www.scopus.com) and Engineering Village (Ei) (www.engineeringvillage.com). This includes EI Compendex (www.ei.org/compendex). The papers will contain linked references, XML versions and citable DOI numbers. You will be able to provide a hyperlink to all delegates and direct your conference website visitors to your proceedings. Authors of high quality papers presented in the symposium will be invited to submit extended version of their papers for publication in international journal special issues.
