On link quality aware routing for industrial wireless sensor networks

Wireless communication is susceptible to attenuation, multi-path and interference. Traditional routing metrics such as hop-count do not perform optimally because they do not consider link quality. For industrial settings, which are characterized by harsh conditions, link quality aware routing can significantly outperform hop-count based routing metrics. This paper presents an overview of the current state of research in this domain and comments on the use of link quality aware routing in industrial wireless sensor networks.
