Cluster Head Selection for the Internet of Things Using a Sandpiper Optimization Algorithm (SOA)

Algorithm 1

CH selection using SOA.

Input: Network population is set of nodes “”.

Output: Best Sandpipers location act as CH.

1: while (true)

2: Initialize search agent and movement of sandpiper .

  //migration phase.

3: Compute and for collision avoidance using Equations (4) and (5).

4: Compute best position of sandpiper using Equation (6).

5: Updating position of the best sandpiper using Equation (8).

  // Attacking phase.

6: Create spiral behavior to attack the prey using Equation (9)-Equation (12).

7: Compute the fitness function Equation (16).

8: if sandpiper reaches its best search agent in the network then.

9:  Best sandpipers act as CH

10: else.

11:  Go to step 1

12: return CH.
