1. A method for modeling movement of users in an environment, the environment including sensors connected in a network, comprising: detecting events due to movement of the users at the sensors; labeling each event according to a particular sensor and time of the event; summing the events for each sensor into a corresponding histogram time interval bin; generating a plurality of co-occurrence matrices from the histograms according to C i , j , δ = ∑ t = 0 T ⁢ ⁢ H i , t ⁢ H j , t + δ , where i and j represent each possible pair of sensors, δ represent time-off-sets, T is a total time for the detecting, t represents a particular time, and H represents the histogram time interval bins.
