Synchronous Firefly Algorithm for Cluster Head Selection in WSN

Table 1

Information maintained in the neighborhood table.

Protocol	Organization type	Objectives	Characteristics
LEACH	Cluster	Improve network life time	CHs are rotated randomly for specific time using threshold.
HEED	Cluster	Increase number of rounds	Nodes with different power levels are assumed.
PEGASIS	Chain	Average energy spent by node	Network knowledge is required for computation
Hierarchical chain based protocols	Chain	Energy × delay	Uses chain scheme with binary values.
EADAT	Tree	Improves the number of available nodes at each round.	Broadcasting is achieved from sink
PEDAP-PA	Tree	Balances node dissipation such that all nodes die simultaneously.	Uses the popular Minimum Spanning Tree to achieve its goal
