Experiences of deploying an indoor building sensor network

Abstract

Monitoring and automatic control of building environment is a crucial application of Wireless Sensor Network (WSN) in which maximizing network lifetime is a key challenge. We investigate the link quality distribution to obtain full coverage of signal strength in a single floor of building environment, experimentally. Our results confirmed the transitional region is particular concern in wireless sensor network since it accommodates high variance unreliable links. The reason due to this transitional region in inside building environment could be the obstacles including concrete/brick walls, partitions, office furniture and other items affect as additional absorption term to the path loss. © 2..
