A base-station centric data gathering routing protocol in sensor networks useful in home automation applications

In the future ubiquitous home network, sensors will collect various home environment data in the home. Since the sensor nodes are equipped with small, often irreplaceable, batteries with limited power capacity, it is essential that the network be energy-efficient in order to maximize its lifetime. Our study, described in this paper, was divided into two classes: the primary class was to set a power-based level and the secondary class was to propose an offer of a home automation using a routing technique centered on a sensor network to set a flooding level. The proposed scheme divides the home into areas such as rooms and locates the WENs in each area. The WENs collect data from sensors and deliver the data to the home base station only. Sensors deliver the data to the WENs or the home base station through the sensor with the stronger power. Performance results show that the proposed scheme is more efficient with a wireless home network.
