[ns] Effect of Propagation delay and Transmission delay in interference calculation

[Sanket Joshi]

Hi,

Current wireless extensions in ns2 consider Propagation delay ( calculated
at the Net-If layer, that depends on the propagation medium ) as well as the
transmission delay ( calculated at the MAC layer, that depends on the link
bandwidth and the packet size).

I am trying to incorporate interference in the physical layer, for which I
will need to consider the "packet overlap" between the current and the
interfering packet. I wanted to know which of these delays ( or rather how
these delays ) are used in calculating the packet overlap. Also, in general
how these two delays effect the interference calculation in real wireless
scenario.

Thanks,
Sanket
