Energy efficiency, low latency, scalability are important requirements for wireless sensor networks. Specially, because sensor nodes are usually battery powered, and highly resource constrained, energyefficient routing sensor routing scheme with low latency, scalability in wireless sensor networks is very important. 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 analysis and 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.
