In this paper, we expose the need for an alternate mecha nism replacing usual database exchange and reliable syn chronization in OSPF for mobile ad hoc environments. A mechanism for link-state database exchanges in wireless ad hoc networks is proposed, aiming at `completing the adap tation of OSPF for ad hoc networks started in [1]. This adapted mechanism is specified with the following applica tions in mind: (i) Reliable diffusion of link-state informa tion replacing OSPF acknowledgements with a mechanism suitable for mobile wireless networks; (ii) Reduced overhead for performing OSPF style database exchanges in a mobile wireless network; (iii) Reduced initialization time when new nodes are emerging in the network; (iv) Reduced overhead and reduced convergence time when several wireless OSPF ad hoc network clouds merge.
