3D Deployment of Unmanned Aerial Vehicle-Base Station Assisting Ground-Base Station

Algorithm 1

PSO algorithm that finds the efficient UAVBS placement.

Input:

The lower and upper bounds of decision variable (Varmin,Varmax), construction coefficients (), maximum number of iterations (), population size ()

Initialization:

;

For to

P(j) = unifrnd(Varmin, Varmax, Varsize)

P_Cost(j) = Objectivefunction(P(j))

P_Best(j) = P(j)

P_Best.Cost(j) = P_Cost(j)

If

   G_Best = P_Best(j)
