[ns] Codes in NS2
HI, i'm trying to implement the channel aware detection algorithm for reducing the selective forwarding attack in wireless mesh network in NS2, can anyone help me in implementing CAD Algorithm or can i get the code for this algorithm n TCL scripts for 2 scenarios Scenario: With normal packet losses (due to bad channel quality or medium access collision). * Create Mesh network of nodes with minimum of 16 or 25 nodes. * Make a node at one end of the network as Source and node at the other end as Destination. * Assign normal packet losses due to channel quality & collisions and calculate threshold value. Scenario 1: With no attacker in the network & CAD algorithm * Source initiates UDP/CBR traffic to send packets to destination. * Get the results of how many packets received by destination out of all packets send by source and show it in graph (PDR). Scenario 2:With attacker & no CAD algorithm * Randomly assign an intermediate node as attacker and drop packets intentionally. * Get the results of how many packets received by destination out of all packets send by source and show it in same graph (PDR). Scenario 2: With attacker & CAD algorithm * Randomly assign an intermediate node as attacker and drop packets intentionally. * Use CAD algorithm to identify the attacker by checking with threshold value of normal packet loss and send the packets in other path not involving attacker. * Get the results of how many packets received by destination out of all packets send by source and show it in same graph (PDR).
Re: [ns] help how to apply evolutionary algorithm in NS2
the function EA in NS2 to get best solution about the problem relay message..is used OLSR because we can set parameter in message and capable OSPF etc...function EA is same like GA...i hope u can help me please From: ÞÕÇÏ Úíäì Ýì ßá ãßÇä mohammed To: fauzan prasetyo eka putra Sent: Wed, May 11, 2011 7:45:32 PM Subject: Re: [ns] help how to apply evolutionary algorithm in NS2 what is the evolutionary algorithm in OLSR that used to run --- On Wed, 5/11/11, fauzan prasetyo eka putra wrote: >From: fauzan prasetyo eka putra >Subject: [ns] help how to apply evolutionary algorithm in NS2 >To: ns-users@ISI.EDU >Cc: ns-users@ISI.EDU >Date: Wednesday, May 11, 2011, 4:45 AM > > > >hi..i m trying to optimize relay message methods in mobile ad hoc network >using >evolutionary algorithm in OLSR. >I thought of simulating the network and apply evolutionary algorithm in >NS2..could everyone help me..or may could >you give me solution what must i do, to implemented EA in NS 2...thanks. > >
[ns] web traffic
Hi, I have just started to use ns-2 to demonstrate the performance of proposed our AQM controller compared to the others. Therefore, I need to construct a traffic. I use a dumbell network with FTP sources, however, I believe in that to show the performance of the proposed controller under a mix traffic will be better. My mind confused on connecting http application agent to the TCP sources. Will the http agents be connected similar to ftp connection? Is there someone to send me a simple program which generates http traffic for a dumbell network\ Thanks for all your interest and time consuming hakki

Hi! Try to work with module MANNASIM (http://www.mannasim.dcc.ufmg.br/). It provides a graphical interface for generating scripts. Also, available are various protocols (LEACH, DSDV, AODV, DSR, DDF ...). I am currently working with him , if you want help just send me e-mail. marlluslust...@gmail.com / marlluslust...@ufpi.edu.br. > > Message: 12 > Date: Sun, 15 May 2011 20:36:21 +0530 > From: Sachin Pal > Subject: [ns] Fwd: [Re] LEACH Sorce code for NS2 > To: ns-users@isi.edu > Message-ID: > Content-Type: text/plain; charset=ISO-8859-1 > > hello... > I am working on the WSN.Please send me LEACH sorce code for ns2. > parameters are those i m working... > a) network deployment areas are 50?50 and100m?100m > b) initial energy of each sensor node is 1 Joule > c) sensor nodes are randomly deployed in the given area > d) each tree is used for 10 rounds > e) each experiment is conducted for 3 simulation scenarios and the average > is used for documentation > f)base station is located at the center of the sensor network > g) MAC layer, 802.11, is used in simulation > > thanks > sachin pal > > > > ___ > Ns-users mailing list > Ns-users@isi.edu > http://mailman.isi.edu/mailman/listinfo/ns-users > > > End of Ns-users Digest, Vol 89, Issue 15 > > -- att, Marllus de Melo Lustosa - lattes -> http://bit.ly/dlm86f / HomePage -> http://www.marllus.com Bacharelando em Ciência da Computação - UFPI Departamento de Informática e Estatística - DIE Grupo de Pesquisa e Estudos em Redes de computadores - GoPER - http://die.ufpi.br/goper/
Re: [ns] HOW TO GET THE POSITION OF NODE IN C++ CODE ??
Hi, Try using this line: Node* node =0; node = Node::get_node_by_address(node_ID); MobileNode* nd = (MobileNode*)node; nd->getLoc(&sx,&sy,&sz); I think u have to include “#include ”, hope this helps...

[ns] Simulating RSSI in ns-2
Hello! I need to test a localization algorithm for wifi networks that uses RSSI readings for ranging. Is there a way I can do this with ns-2? I have RSSI in field measurements for a small number of nodes and I would like to test my algorithm on a scenario that has a more considerable number of nodes. Is there a way I can accomplish this with ns-2? Does it offer simulated RSSI values? Many thanks!
[ns] can not change RED to original form (without gentle)
Hi everyone, i just want to know how origin red works. But since default red was change to gentle-red ( http://www.isi.edu/nsnam/archive/ns-users/webarch/2001/msg01414.html) i can't change it back to the original one i already change the queue parameter in my tcl file Queue/RED set gentle_ false and/or change the /ns/tcl/lib/ns-default.tcl gentle parameter to false, but nothing happen is there anyone know how to fix this thanks for attention, -aquila yoma
