Minimum spanning tree topology in real zigbee-arduino sensor network
Résumé
In this paper, we present a real indoor application for improved”Cluster Tree” network using Zigbee sensor nodes integrated with”Arduino” microcontrollers where the main goal is to study the efficiency of our improved clustering topology based on Minimum Spanning Tree (MST) construction under real conditions. Our system is based on many sensor nodes deployed all over a building to monitor temperature and humidity and detect any brutal temperature increase. These nodes are based on simple, cheap and easily programmed equipment. while several simulations using NS- 2 and other simulators has been conducted in many other works to study the efficiency of a network based on MST, our application tests this topology in real conditions to ensure it effectiveness in a Zigbee network. Our developed system provides an easy interface for programming and displaying results. All sensed data is sent to the coordinator which forwards it to the user’s pc to be viewed by the user. This paper also presents some performances of this discussed topology obtained by real conditions tests. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2015.
