In the emerging ubiquitous home, sensors will be placed everywhere in the house and collect various physical data such as temperature, humidity, and light to provide information to consumer electronics devices.
Because sensors have limited battery power, energy-efficient routing is important. the authors present a new sensor routing scheme that provides energy-efficient data delivery from sensors to the home base station. The proposed scheme divides the home area into sector and locate a manager node to each sector. The manager node receives collected data from sensors and deliver the data to the base station through the sortest path of the 2-dimensional (x,y) coordinates.

In the conventional sensor routing scheme, when each sensor node detects an event, it broadcasts the event to all sensor nodes within one hope range. then all sensor nodes within one hope will repeatedly broadcast the message to the next nodes. These processes are recursively performed until the event reaches the base station. This conventional scheme could lead to excessive drain of limited battery power and increase collisions in wireless transmission.

The authors present a new sensor routing scheme for home automation networks, namely RDSR (Relative Direction based Sensor Routing). The scheme divides the home area into sectors and locates a manager node to each sector. The manager node receives collected data from sensor devices in its corresponding sector and then transfers the data to the base station.

Their system model consists of gateway, a base station, several nodes, and a number of sensor nodes. The gateway is a home gateway that delivers commands received from a person ot out of the house to the base station in the house and controls messages received from the base sattion. The base station is a sensor node that has more computational ability and memory than general sensor nodes. It receives commands from the gateway and sends queries to sensor nodes. It also collects data from sensor nodes and delivers control message to the gateway. the base station is located at the coordinate center of the house.
Manager nodes and sensor nodes have ability to collect physical data and deliver the data to other nodes within one hope distance. Manager nodes are located in some predetermined position while other sensor nodes are randomly distributed in the house.
