The Internet of Things is a vision in which miniature low-power wireless devices are embedded into surrounding physical objects—things—to make these objects members of the global network. To this end, the devices have to support the fundamental Internet technology: routing.

However, traditional routing algorithms for the Internet are poorly suited for the resource-constrained wireless micro-devices. Likewise, existing algorithms targeting such devices have their limitations. More specifically, they are either practical, in the sense that they are used in actual real-world deployments, or scalable, in the sense that they can support networks comprising thousands of nodes, but not both.

Our project thus aims to develop a routing protocol for networks of low-power wireless micro-devices that would be simultaneously practical and scalable.
