LEACH

Stands for Low Energy Adaptive Clustering

Hierarchy.

Simple Routing Protocol in WSN(Wireless Sensor

Network)

MAC Protocol Integrated with Clustering

# LEACH is a cross layer protocol.

LEACH (CONTD)

Goal:

Low Energy Consumption required to create and

maintain clusters in order to improve lifetime

LEACH (SCENARIO)

SINK NODE

Primary Controller in WSN

Initiate, terminate and route communication around

the network

CLUSTER HEAD

Cluster Head:

From each Cluster, one sensor is elected as Cluster

Head, which

- Collects Data from surrounding

sensors in that cluster.

-Passes that data to the Base Station or

the next Cluster Head.

LEACH uses Dynamic Clustering Method i.e job of

Cluster Head changes after some time.

IMPLEMENTATION IN NETSIM

Node Cluster Head Sink Node

Static Routes have been defined

CH1 CH3 SINK NODE

CH2 CH4

IMPLEMENTATION IN NETSIM(CONTD)

If Network-out Event

Device ID == Source ID -the Next hop=CH of cluster

Device ID != Source ID -Next hop = Static route mentioned

If Network-In Event

Device ID == Destination ID -accept the packet for higher layer

Device ID != Destination ID -Generates Network-out event

and perform above steps
