Introduction

The main purpose of EMR is to address the hot-spot issue in WSNs so that the network energy could be better utilized.

• The operation of EMR is as following:
• First, some CH candidates are selected;
• Second, these candidates compete to be the final CH;
• Third, the CHs announce their role and allow non-CH nodes to join them as member nodes to form the cluster;
• Fourth, the CHs collect the data packets from their respective member nodes;
• Finally, the CHs aggregate these packets as one summary packet of the cluster and deliver them to the sink.

Please note that the competition range of the CH candidates to be the CHs are determined by the probability of nodes to be the CH, acquired by the mathematical analysis which aims to equalize the node lifetime across the network.

Installation

Hardware and Software Requirements

Installing the EMR protocol requires the following hardware tools and software packages:

• ​Linux PC (Ubuntu)
• ​TinyOS-2.x

• ​SCU software package
• At least 2 TelosB sensor nodes

We assume that the installation PC is running a Linux operating system and the ​TinyOS-2.x has been installed and configured properly on it. We skip the installation of TinyOS here and refer to ​TinyOS-2.x if needed. We describe the installation and configuration steps in the following for the ​Ubuntu operating system.
