A Proficient Bee Colony-Clustering Protocol to Prolong Lifetime of Wireless Sensor Networks

Algorithm 1

Pseudocode of clustering.

Begin
//Initialization//
(1)	Base station broadcasts beacon
(2)	All nodes calculate Euclidian distance
	//Cluster head selection phase//
(3)	Generate the initial population
(4)	Set cycle to 1
(5)	Repeat
(6)	For each sensor
(7)	Launch artificial bee colony algorithm
(8)	Select CHs
(9)	Cycle = cycle + 1
(10)	Until Maximum Cycle Number
(11)	End For
	//cluster-member recruitment//
(12)	Set CH cycle to 1
(13)	Repeat
(14)	For each CH
(15)	Set Hop Cycle to 1
(16)	Repeat
(17)	For each CH broadcast REQUEST message;
(18)	If (non-CH node neighbours receive REQUEST message)
(19)	Then, non-CH node neighbours send ACCEPTED message to CH;
(20)	End if
(21)	Hop Cycle = Hop Cycle + 1
(22)	Until Maximum Hop Cycle Number
(23)	End For
(24)	CH cycle = CH cycle + 1
(25)	Until Maximum CH cycle Number
(26)	End For
	End
