Probability that 3 random wireless nodes with radio range 0.1 in a unit square can communicate?

Imagine three wireless nodes A,B,C (e.g. people with wireless laptops) at random locations in a square area (unit square). Each laptop has circular communication range of 0.1. What is the probability that they all can communicate? Note that this requires

A has both B and C in its radio range,
OR B has both A and C in its radio range,
OR C has both A and B in its radio range.

Let any of them is situated anywhere in the square.
It has circular communication range r=0.1
It means it has the area =pi*r^2= 0.01pi where another laptop should be to communicate ( the whole area=1)

The probability that it really will be there= 0.01pi/1=0.01pi

Remember the third one?
The probability it will be there as well = 0.01pi*0.01pi=0.0001pi

Answer: 0.0001pi

On a D-Link Wireless Adapter is the node id the Mac address? On a D-Link Wireless Adapter is the node id the Mac address?

In all likelihood, yes. You should be able to see the node in the router, then compare it to the MAC on the adapter.

Has anyone setup a wireless only office before (about 100 nodes)? Would you do it again, and why?

No way... my husband works for one of the major soft drink companies as their I.T. guy. One of their departments wanted wireless... he advised them it wasn't a good idea, but they insisted. Now they are constantly saying they can't connect to the network or the internet. He has no problem telling them I told you it's not a good idea.

I hope this helps.

Ns2 wireless, can we configure individual nodes i.e can we give different queueing for set of nodes.thank you? Ns2 wireless, can we configure individual nodes i.e can we give different queueing for set of nodes.thank you?
