BioWSN: A Bio-Inspired Method for Optimization of Routing in Wireless Sensor Networks

Algorithm 1

Clustering.

	: set of sensor nodes
	m: number of grey wolves
	: Random generation of grey wolves
	Setting initial values of , , and
	: total number of iterations
	Fitness evaluation of each grey wolf
	: the best solution
	: second best solution
	: third best solution
	whiledo
	for each in do
	Update the position of
	end for
	Update , , and
	Evaluate the fitness of all grey wolves using equations (17) and (18)
	Map a new position for and move it there if it is improved
	Update , , and
	end while
	return as the solution to assign sensor nodes to cluster heads
