2. 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.

3. LEACH (CONTD)
 Goal:
Low Energy Consumption required to create and
maintain clusters in order to improve lifetime

4. LEACH (SCENARIO)

5. SINK NODE
 Primary Controller in WSN
 Initiate, terminate and route communication around
the network

6. 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.

9. IMPLEMENTATION IN NETSIM
 Node  Cluster Head  Sink Node
 Static Routes have been defined
CH1  CH3
SINK NODE
CH2  CH4

11. 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
