Hi Muhamad, I tried your script, and understood how you did it. However, I did not observe any data packet delivered from source to host node. Also, your scenario looks a little bit complex for me.
So, I designed a simple scenario which has only two nodes, with different receiving ranges (n0's range > n1's). I also used DSR to transmit one packet from n0 to n1, and n1 to n0. There was no data packet delivery, because DSR requres a two-way communicaiton for route discovery. But I did observed the consequence of having different receiving range on n0 and n1: the broadcast packets from n1 can reach n0, but those from n0 cannot reach n1. I think this verifies that we can indeed use two different receiving ranges in one simulaiton. The following is my tcl script. You can find more detail on my blog, http://ns-3.blogspot.com/. Thanks. tcl script: ------------------------- # n0 and n1 use the same transmission power. # n0 has a receiving range of 250m, n1's receiving range is 160m. # n0 and n1 are 200m away from each other. # n1 cannot receive routing requests broadcast by n0; # however, n0 can receive routing requests broadcast by n1. # ========================================================== #Definition # ========================================================== set opt(chan) Channel/WirelessChannel ;# channel type set opt(prop) Propagation/FreeSpace ;# radio-propagation set opt(ant) Antenna/OmniAntenna ;# Antenna type set opt(ll) LL ;# Link layer type set opt(ifq) CMUPriQueue ;# Interface queue set opt(ifqlen) 100 ;# max packet in ifq set opt(netif) Phy/WirelessPhy ;# network interface set opt(mac) Mac/802_11 ;# MAC type set opt(nn) 2 ;# number of mobilenodes set opt(rp) DSR ;# routing protocol set opt(x) 1000 set opt(y) 1000 set opt(seed) 0.0 set opt(stop) 10.0 # ========================================================== # Initialize Global Variables # ========================================================== set ns [new Simulator] $ns use-newtrace set trace [open out.tr w] $ns trace-all $trace set namtrace [open out.nam w] $ns namtrace-all-wireless $namtrace $opt(x) $opt(y) # ========================================================== # set up topography object # ========================================================== set topo [new Topography] $topo load_flatgrid $opt(x) $opt(y) # ========================================================== # Create God --> General Operations Director # ========================================================== create-god $opt(nn) # ========================================================== # Create channel (koneksi wireless) # ========================================================== set chan_1 [new $opt(chan)] # ========================================================== # configure and create nodes # ========================================================== $ns node-config -addressType expanded \ -adhocRouting $opt(rp) \ -llType $opt(ll) \ -macType $opt(mac) \ -ifqType $opt(ifq) \ -ifqLen $opt(ifqlen) \ -antType $opt(ant) \ -propType $opt(prop) \ -phyType $opt(netif) \ -topoInstance $topo \ -agentTrace ON \ -routerTrace ON \ -macTrace OFF \ -movementTrace OFF \ -channel $chan_1 # ==================================================================== # create node 0， receiving range 250m, carrier sensing range 500m # ==================================================================== Phy/WirelessPhy set CPThresh_ 10.0 Phy/WirelessPhy set CSThresh_ 9.21756e-11 ;#550m Phy/WirelessPhy set RXThresh_ 4.4613e-10 ;#250m Phy/WirelessPhy set bandwidth_ 512kb Phy/WirelessPhy set Pt_ 0.2818 Phy/WirelessPhy set freq_ 2.4e+9 Phy/WirelessPhy set L_ 1.0 Antenna/OmniAntenna set X_ 0 Antenna/OmniAntenna set Y_ 0 Antenna/OmniAntenna set Z_ 0.25 Antenna/OmniAntenna set Gt_ 1 Antenna/OmniAntenna set Gr_ 1 set node_(0) [$ns node] $node_(0) random-motion 0 $node_(0) set X_ 0.0 $node_(0) set Y_ 0.0 $node_(0) set Z_ 0.0 # =================================================================== # create node 1, receiving range 160m, carrier sensing range 400m # =================================================================== Phy/WirelessPhy set CPThresh_ 10.0 Phy/WirelessPhy set CSThresh_ 1.74269e-10 ;#400m Phy/WirelessPhy set RXThresh_ 1.08918e-9 ;#160m Phy/WirelessPhy set bandwidth_ 512kb Phy/WirelessPhy set Pt_ 0.2818 Phy/WirelessPhy set freq_ 2.4e+9 Phy/WirelessPhy set L_ 1.0 Antenna/OmniAntenna set X_ 0 Antenna/OmniAntenna set Y_ 0 Antenna/OmniAntenna set Z_ 0.25 Antenna/OmniAntenna set Gt_ 1 Antenna/OmniAntenna set Gr_ 1 set node_(1) [$ns node] $node_(1) random-motion 0 $node_(1) set X_ 200.0 $node_(1) set Y_ 0.0 $node_(1) set Z_ 0.0 # UDP connections between from node_(0) to node_(1) set udp_(0) [new Agent/UDP] $ns attach-agent $node_(0) $udp_(0) $udp_(0) set fid_ 1 set null_(0) [new Agent/Null] $ns attach-agent $node_(1) $null_(0) set cbr_(0) [new Application/Traffic/CBR] $cbr_(0) set packetSize_ 512 $cbr_(0) set rate_ 200kb $cbr_(0) set maxpkts_ 1 $cbr_(0) attach-agent $udp_(0) $ns connect $udp_(0) $null_(0) $ns at 1.0 "$cbr_(0) start" set udp_(4) [new Agent/UDP] $ns attach-agent $node_(1) $udp_(4) $udp_(4) set fid_ 2 set null_(4) [new Agent/Null] $ns attach-agent $node_(0) $null_(4) set cbr_(4) [new Application/Traffic/CBR] $cbr_(4) set packetSize_ 512 $cbr_(4) set rate_ 200kb $cbr_(4) set maxpkts_ 1 $cbr_(4) attach-agent $udp_(4) $ns connect $udp_(4) $null_(4) $ns at 5.0 "$cbr_(4) start" $ns at $opt(stop).0002 "puts \"ns EXITING...\" ;
