Node autoconfiguration is one of the main issues in self-organized networks. One class of approaches relies on hierarchical organization of nodes. This kind of structuration aims to deal with scalability issues, especially for wireless networks. But building and maintaining a hierarchy is generally expensive for these resource-limited networks. We propose a low-cost distributed, hierarchical, location-based address au-toconfiguration protocol. Each node infers its address from those of its one-hop neighbors and from its relative position to them. In this way we obtain a globally-consistent organization resulting from local interactions only. This reduces the latency and the overhead generated during address configuration. Moreover this scheme is the first step towards the design of a scalable routing protocol taking advantages of the proposed hierarchical addressing.
