[ns] What is diffrent between Radio transmission range and radio interference range ?
Hi all What is diffrent between Radio transmission range and radio interference range? and how to calculate they??? please guide me -- Amin Irandoost
[ns] please read email emergency
Hi all Why changing CBR rate of node doesn't effect on energy consumption of nodes that use SMAC protocol for MAC layer?? For example in 5*5 grids with 25 nodes, node 1 is sender and node 25 is Sink . Please guide me Very Thanks in advanced I'm waiting for your reply -- Amin Irandoost
[ns] why no body doesn't help !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Hi all
In wireless scenario that picture of this show at below
Node 0 is sender and node 24 is receiver
I want to use UDP agent for this nodes
I use follow code for this purpose
Please tell me is the following file correct and suitable?
Why the CBR interval has not effect on time when the nodes' energy is
finished?
picture of nam file that show my topology is :
