Dear all, We all know that to set the the interference and transmission range we use the follwing commands: Phy/WirelessPhy set CSThresh_ 3.1622777e-12 ;# Carrier Sensing threshold Phy/WirelessPhy set RXThresh_ 3.1622777e-11 ;# receiver signal threshold

[ns] Queues in ns-2

Dear ns-users, I want to make sure of the operation of interface queues in ns-2 (again forgive me for this stupid question). Does the interface queue of a node hold all the packets that arrive at the mac up to the routing layer and vice versa (i.e. the packets that arrive at the rou

[ns] Is there a method to idetify the ip address of the RTS sender and reciever at the mac layer?

Dear ns-users, forgive me for this stupid question, but as we know RTS and CTS packets are sent and recieved at the mac layer. So, no ip header is added to them. At the mac layer I want to record the number of sent RTS packets from a node to its neighbors, and I need the ip address of the
