Address autoconfiguration is an important issue for ad hoc networks in order to provide autonomous networking and self-management. The IP address assignment for ad hoc nodes requires a distributed procedure that resolves all the address collisions in a dynamic network with fading channels, frequent partitions, and joining/leaving nodes. We propose a filter-based addressing protocol for autoconfiguration of mobile ad hoc networks that is lightweight and robust to packet losses. We present a probabilistic analysis of address collisions and discuss filters functionalities in the address autoconfiguration. We evaluate the performance of our protocol for static and mobile scenarios, considering joining nodes and partition mergings. Simulation results show that our protocol resolves all the address collisions and reduces up to 22 times the control traffic when compared to the other addressing protocols.
