Route and service discovery in wireless multi-hop networks applies flooding or gossip routing to disseminate and gather information. Since packets may get lost, retransmissions of lost packets are required. In many protocols the retransmission timeout is fixed in the protocol specification. In this paper, the authors demonstrate that optimization of the timeout is required in order to ensure proper functioning of flooding schemes. Based on an experimental study, they apply percolation theory and derive analytical models for computing the optimal restart timeout.
