Does anyone have good parameters to simulate a 802.11b interface card with the new 802.11Ext layer ?
I tried to use the parameters I used in NS-2.31, but the results now are very different (mainly because there is no more RXTresh_). With these parameters, nodes can communicate even at carrier sensing range (although the carrier sensing range should be 2 to 3 times the communication range). So I tried with the default Phy/WirelessPhyExt parameters and the results are similar (but for the communication range, since the transmission power changes) These are the parameters I use. They were taken from the specifications of an Avaya card : set val(chan) Channel/WirelessChannel ;#Channel Type set val(prop) Propagation/TwoRayGround ;# radio-propagation model set val(netif) Phy/WirelessPhyExt ;# network interface type set val(mac) Mac/802_11Ext ;# MAC type set val(ifq) Queue/DropTail/PriQueue ;# interface queue type set val(ll) LL ;# link layer type set val(ant) Antenna/OmniAntenna ;# antenna model set val(ifqlen) 50 ;# max packet in ifq Phy/WirelessPhyExt set CSThresh_ 6.309573444801943e-12 Phy/WirelessPhyExt set Pt_ 0.031 Phy/WirelessPhyExt set freq_ 2.457e9 Phy/WirelessPhyExt set L_ 1.0 Phy/WirelessPhyExt set bandwidth_ 11e6 Phy/WirelessPhyExt set trace_dist 400; Phy/WirelessPhyExt set BasicModulationScheme_ 0 ;# BPSK Mac/802_11Ext set dataRate_ 11Mb Mac/802_11Ext set CWMin_ 31 Mac/802_11Ext set CWMax_ 1023 Mac/802_11Ext set SlotTime_ 0.000020 Mac/802_11Ext set SIFS_ 0.000010 Mac/802_11Ext set PreambleLength_ 144 Mac/802_11Ext set PLCPHeaderLength_ 48 Mac/802_11Ext set PLCPDataRate_ 1.0e6 Mac/802_11Ext set RTSThreshold_ 2000 Mac/802_11Ext set ShortRetryLimit_ 7 Mac/802_11Ext set LongRetryLimit_ 4 Thanks for your help ! -- View this message in context: http://www.nabble.com/Parameters-for-802.11b-on-NS-2.33-802.11Ext-tp18010313p18010313.html Sent from the ns-users mailing list archive at Nabble.com.
