[BonnMotion] TLW mobility model

[Alexander Bothe]

Dear Daniel,

looks like the current implementation of the TLW model ignores the x and
y parameters and uses s instead to set both dimensions. So, specifying s
as 1000 results in your requested scenario space of 1000m x 1000m.

Therefore, using
bm -f TLW0 TLW -d 3600 -n 1 -R 6311 -a 1.5401133655865746 -b
0.8990860035786055 -s 1000 -m 0 -M 1200 -l 10 -L 100 -c 2

and

bm IntervalFormat -f TLW0 -s -l 1

results in a node, that stays within the scenario area:
0 0.0 179.0 848.0
0 1.0 178.39999999999998 847.4
0 2.0 177.8 846.8000000000001
0 3.0 177.2 846.1999999999999
0 4.0 176.6 845.6
0 5.0 175.99999999999997 844.9999999999999
0 6.0 175.4 844.4000000000001
0 7.0 174.8 843.8
0 8.0 174.2 843.2
0 9.0 173.6 842.5999999999999
0 10.0 173.00000000000003 842.0
0 11.0 172.4 841.4
0 12.0 171.8 840.8000000000001
0 13.0 171.2 840.2
0 14.0 170.6 839.6
0 15.0 170.0 839.0
0 16.0 169.4 838.4
0 17.0 168.8 837.8
0 18.0 168.2 837.1999999999999
...

Since others may have the same issue, I also forward this conversation
