LEACH

The LEACH (Low-energy adaptive clustering hierarchy) is a hierachical adhoc routing protocol for Wireless Sensor Networks. It is based on the paper by W.R. Heinzelman et.al titled Energy-efficient communication protocol for wireless microsensor networks published in 2000. The code in this repository is an implementation of it for the INET Framework of the OMNeT++ simulator.

Unlike the standard LEACH protocol, the implemented version uses IEEE 802.15.4 standard to manage to the Physical and Data-Link layers. However as described in the original paper, the setup phase runs on CSMA with the steady state phase operating on slotted TDMA. Accordingly the stages are as follows;

Follow the below steps to run the simulation.

  1. Prerequisites

  2. Install OMNeT++, INET Framework -

  3. Run models

1. Prerequisites

These models have been tested on the following versions of INET and OMNeT++.

  • OMNeT++ version 5.6.2

  • INET Framework version 4.2.5

2. Install and Build

Follow the following procedure to install and build the models.

  1. Install and build OMNeT++

  2. Create a new workspace in the OMNeT++ IDE

  3. Install and build the INET Framework in the created workspace

  4. Copy the LEACHnode and leach directories present in the node and routing directories respectively to the node and routing directories in the your installed INET project.

  5. Import the LEACH3 project into the workspace via Existing project into Workspace option. Link it with INET using properties > project references and ticking on the inet option.

  6. Rebuild INET and LEACH3 projects

3. Running Models

  • Use the omnetpp.ini files provided in the LEACH3 directory to run the simulation

  • Important parameters are referenced via comments within the omnetpp.ini file.

File structure

The simulations consists of 3 layers organized by their directories;

  • Simulation components - <workspace_home>/LEACH3

  • Node intermediary layer - <workspace_home>/inet4/src/inet/node/LEACHnode

  • Node routing logic layer - <workspace_home>/inet4/src/inet/routing/leach

Licenses

This model is released under LGPL v3.0 license.
