NetSim - Implementing LEACH in WSN
Download as PPTX, PDF0 likes256 views
This document summarizes the implementation of LEACH (Low Energy Adaptive Clustering Hierarchy), a routing protocol for wireless sensor networks, in the NetSim network simulator. LEACH is a cross-layer protocol that uses dynamic clustering to select cluster heads in order to minimize energy consumption and extend network lifetime. Sensor nodes transmit data to their cluster heads, which then pass the data to the sink node. The document describes how NetSim implements LEACH using static routes between cluster heads and the sink node, and how network-in and network-out events are handled to route packets to their destinations.

NetSim - Implementing LEACH in WSN
- 1. LEACH NetSim Implementation Address: Tetcos 214, 7th Main, 39th A Cross, 5th Block, Jayanagar Bangalore – 560041 Phone: + 91 80 26630624
- 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
- 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
