Optimization of Self-Directed Target Coverage in Wireless Multimedia Sensor Network

Algorithm 1

Single-node single-interested target self-direction coverage algorithm.
Input: multimedia sensor node , interested target , sensing radius , FoV vertex angel , sensing direction
Output:
Define Rotate Direction; // rotated direction of node, value as CLOCKWISE or ANTICLOCKWISE
Define Rotate Angle; // rotated angel of node
Calculate ; // distance between multimedia sensor node   and interested target
IF THEN
;
RETURN ;
END
IF THEN
Calculate ; // the angel between sensing direction to interested target
IF THEN
   ;
  RETURN ;
END
IF THEN
  RotateDirection = anticlockwise;
  RotateAngle = ;
END
IF THEN
  RotateDirection = clockwise;
  RotateAngle = ;
END
ROTATE( , RotateDirection, RotateAngle); // rotated RotateAngle to RotateDirection
RETURN .
