In this paper, we develop a simple autoconfiguration mechanism for OLSR networks. The mechanism aims at solving the simple, but common, probem of one or more new nodes emerging in an existing network. We propose a simple solution, which allows these new nodes to acquire an address and participate in the network. Our method is simple, both algorithmically and in the requirements to the network. While we recognize that this is a partial solution to the general autoconfiguration problem, we argue that the mechanism described in this paper will satisfy the requirements from a great number of real-world situations.
