As large-scale sensor networks become more feasible, properties such as stateless nature and low maintenance overhead make position-based routing increasingly more attractive. Motivated by the fact that sensor networks would probably be deployed in a three-dimensional space, the authors present a novel 3D Geographical Routing (3DGR) algorithm that makes use of the position information to route packets from sources to destinations with high path quality and reliability. The locality and high scalability of this algorithm make it suitable for wireless sensor networks. It provides high adaptability to changes in topology and recovery of link failures which increases its reliability. They also incorporate battery-aware energy efficient schemes to increase the overall lifetime of the network.
