Robust Sensor Networks in Homes Via Reactive Channel Hopping

Free registration required

Executive Summary

Home Area Networks (HANs) consisting of wireless sensors have emerged as the enabling technology for important applications such as smart energy and assisted living. A key challenge faced in deploying robust Wireless Sensor Networks (WSNs) for home automation applications is the need to provide long-term, reliable operation in the face of the varied sources of interference found in typical residential settings. To better understand the channel dynamics in these environments, the authors performed an in-depth empirical study of the performance of HANs in ten real-life apartments. The empirical study leads to several key in-sights into designing robust HANs for residential environments.
