Algorithm 1 Predicting the probability of

u_{i}

directly contacting a Wi-Fi Access Point (AP) within a time constraint

Input: the starting region

r_{s}

, the starting time interval t, the stop time interval

t_{e}

.
Output:

P_{i}^{D}

Initialize:

P_{i}^{D} = 0, p_{s} (t) = 1

1: OneStepTransition() {
2: if (

r_{s}

contains a Wi-Fi AP) then
3:

P_{i}^{D} + = p_{s} (t)

;
4: else
5: Getting the staying time intervals d and

p_{s}^{t} (d)

using (2);
6:

t + = d

;
7: if

(t < t_{e})

then
8: for every possible next region

r_{a}

do
9: Calculating

p_{s a} (t)

using (1);
10: Calculating

p_{a} (t)

using (3);
11:

r_{s} = r_{a}

;
12:

p_{s} (t) = p_{a} (t)

;
13: Calling OneStepTransition()
