Algorithm 3

(1) Sleep until periodic  _timer expires

(2) For each vehicle () in the FLSG do

  (1) Analyze the Pos, Sp and Yr.

  (2) If any of the following case arises

        (1) Case 1: pres_val (Pos) = prev_val (Pos)

        (2) Case 2: pres_val (Sp) differs with prev_val (Sp) by 30 Km/h

        (3) Case 3: pres_val (Yr) differs with prev_val (Yr) by 30 degrees.

   then

        (1) Set Dp as Abnormal.

   else

        (1) Set Dp as Normal.

(3) Return
