How to color nodes in NS2

You can color the nodes in NS2. It is bit tricky to color them in a wireless network. We can do this by following code.

set node0 [$ns node]
$node0 color "blue"
$ns at 0.0 "$node0 color blue"

    How many types of colors are possible ?
    And also can we mention the color in hexadecimal values like for blue can we write #0000FF ??

Runtime packet loss calculation in NS2

Hello friend, here I am going to present a method to calculate the runtime packet loss. I am going to show this using ns2 2.34 and AODV.       Sometime we require packet loss to calculate trust value (in case of Trust Based protocols where it is done by no. of packets sent - no. of packets received).        I am going to show the calculation for a particular pair of nodes. Steps involved:- A) We will have to add a node as a malicious node which will drop the packets      intentionally. You can add a malicious node using this link. B) Second, we'll set the AODV in promiscuous mode, where every node will      listen to its neighbors. 1) We need to modify in total 3 files to set AODV in promiscuous mode, so it's     good to take a backup of it.     Files are: ns-allinone-2.34/ns-2.34/aodv/aodv.cc ns-allinone-2.34/ns-2.34/aodv/aodv.h ns-allinone-2.34/ns...

How to use promiscuous mode in AODV NS2

Introduction:-           In Promiscuous mode each node in the network listens the packets transmitted by its own neighbor nodes.            In NS-2, some time we have to calculate the packet drops or analyze the process. For the same we need to set the network to operate in promiscuous mode. Here, I am going to explain how we can set our wireless network in promiscuous mode with AODV as Routing protocol using NS2 simulator. 1) We need to modify in total 3 files, so it's good to take a backup of it.     Files are: ns-allinone-2.34/ns-2.34/aodv/aodv.cc ns-allinone-2.34/ns-2.34/aodv/aodv.h ns-allinone-2.34/ns-2.34/tcl/lib/ns-mobilenode.tcl 2) Open the file ns-allinone-2.34/ns-2.34/aodv/aodv.h in your favorite editor     and make the changes as shown in blue color.   #include <mac.h>   class AODV: public Tap, public Ag...

How to add trust table in NS2.

I am assuming AODV protocol. In rtable.cc add below code trust_entry::trust_entry() {    //Initialize as per your need. } trust_entry::~trust_entry() {   //Deconstruct as per your need. } trust_entry* trust_store::trust_lookup( nsaddr_t node_id) {      trust_entry *rp = trusthead.lh_first;      for (; rp; rp = rp->trust_link.le_next) {              if (rp->node_id == node_id)                  break;      }     return rp; } void trust_store::trust_delete( nsaddr_t node_id) {     trust_entry *rp = trust_lookup(node_id);     if (rp)     {         LIST_REMOVE(rp, trust_link);         delete rp;     } } trust_entr...
