[ns] ns]questions about packets sending in wireless

[xiaoning@sjtu.edu.cn]

Hi, everyone!

I'm using NS2 for doing wireless mesh network tests and I can not find what is the policy used in NS2 for packet sending in wireless network simulation. And I have two questions here:

1> in a wireless network, what is the distribution of the frequency of sending packets?
2> if a packet travels two hops before it can reach its destination, should I count this packet twice?

Any suggestion would be thankful.
