With advances in processor and wireless communication technologies, sensor networks
will be used everywhere in the future life. Home networks are one of the good environments
that sensor networks will be deployed. In sensor networks, many sensor devices detect
various physical data and send them to the base station. In this paper, we present a sensor
routing scheme, EESR (Energy-Efficient Sensor Routing) that provides energy-efficient data
delivery from sensors to the base station. The proposed scheme divides the 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
through the shortest path of the 2-dimensional (x, y) coordinates. In this process, we use
relative direction based routing in the 2-dimensional (x, y) coordinates in wireless sensor
networks. Via simulation, we show that the proposed scheme achieve significant energy
savings and outperform idealized transitional schemes (e.g., broadcasting, directed diffusion,
clustering) under the investigated scenarios.
