An Immune Cooperative Particle Swarm Optimization Algorithm for Fault-Tolerant Routing Optimization in Heterogeneous Wireless Sensor Networks

Algorithm 1

The ICPSOA for fault-routing problem.

Input: 𝑃_ST𝑜: The information parameters of nodes

     𝑃_Gen: The iterated generations for searching process

Output: fitness(𝑝_𝑖): The global optimal fitness

Process:

Step 1: Initialization: Generate initial particle swarm parameter.

Step 2: Immunization: Immune clone, mutation, particle selection and restrain.

Step 3: If termination criterion conditions are satisfied, go to  Step 5; else go to

    Step 4.

Step 4: Update: Update the velocity and position of each sub-swarm and particle.

Step 5: Output: Output the global optimal fitness of the particle swarm. Ends.
