OMNET++ CODE FOR LEACH PROTOCOL

OMNET++ CODE FOR LEACH PROTOCOL Leach referred as Low Energy Adaptive Clustering Hierarchy.LEACH is a TDMA based MAC Protocol.(LEACH) protocol is a TDMA based MAC protocol. OMNET++ CODE FOR LEACH PROTOCOL aim of this protocol is to improve the lifespan of wireless sensor networks by lowering the energy consumption required to create and maintain Cluster Heads.

Features of leach:

• Load balancing is achieved.
• All nodes die at a time.
• Better utilization and system lifetime.

Techniques:

Techniques which are used in leach to achieve the design goals are mentioned below

• Low energy media access control.
• Application specific data processing like data aggregation and compression.
• Localized control of data transfers.
• Randomized, adaptive, self-configuring cluster formation.

Procedure of leach routing protocol:

• Cluster head selection.
• Steady state phase.
• Cluster formation.
• LEACH-C: BS cluster formation.
