Method for Patching Three-Dimensional Surface Coverage Loopholes of Hybrid Nodes in Wireless Sensor Networks

Algorithm 1

3D-SCHDR algorithm.

1 Input:, , , , , , ;

2 Output: set the number of iterations and repeat lines 7-18 until the coverage loopholes are repaired;

3 //select any reference node with coordinates

4 Neighbor nodes

5 Maxiter = 150//set the maximum number of iterations

6 Max_Step =0 ~ 10//set the maximum moving step size of the node

7 if

8 =0; //no coverage loopholes

9 else if

10 =0;

11 else if

12 =0;

13 else

14 ; //exist coverage loopholes

15 end

16 Calculate moving direction and distance according to equations (8)–(15);

17 Using the virtual force

18 Location movement
