A Hybrid Sensor Network System for Home Monitoring Applications

This paper presents the design and implementation of a home monitoring system based on hybrid sensor networks. The system follows a three-layer architecture which combines hybrid-node networking with web access. An enhanced sensor node has been designed and fabricated to add controlled mobility to wireless sensor networks. The mobile node is capable of simple planar motions and is easy to be controlled through different user interfaces. A testbed including the static nodes as well as the mobile node has also been created for validating the basic functions of the proposed hybrid sensor network system. Network repair and event tracking capabilities of the mobile sensor node were tested. Stability of the proposed system in longtime home monitoring tasks was also verified.
