RELATIVE LOCATION OF A WIRELESS NODE IN A WIRELESS NETWORK

In one embodiment, a method includes computing a probability surface corresponding to the location probability of the wireless node within a physical region based on the received signal strength data associated with a wireless node and an RF model of the physical region; computing, based on the probability surface, an aggregate probability (Pin) of the wireless node being inside a perimeter defined with the physical region; computing, based on the probability surface, an aggregate probability (Pout) of the wireless node being outside the perimeter; computing a probability ratio of the aggregate probabilities Pin to Pout; and determining whether the wireless node is inside or outside the perimeter based on a comparison of Pout and Pin.
