An ad-hoc network is the cooperative engagement of a collection of mobile nodes without the required inter- vention of any centralized access point or existing in- frastructure. In this paper we present Ad-hoc On De- mand Distance Vector Routing (AODV), a novel algo- rithm for the operation of such ad-hoc networks. Each Mobile Host operates as a specialized router, and routes are obtained as needed (i.e., on-demand ) with little or no reliance on periodic advertisements. Our new routing algorithm is quite suitable for a dynamic self- starting network, as required by users wishing to utilize ad-hoc networks. AODV provides loop-free routes even while repairing broken links. Because the protocol does not require global periodic routing advertisements, the demand on the overall bandwidth available to the mo- bile nodes is substantially less than in those protocols that do necessitate such advertisements. Nevertheless we can still maintain most of the advantages of basic distance-vector routing mechanisms. We show that our algorithm scales to large populations of mobile nodes wishing to form ad-hoc networks. We also include an evaluation methodology and simulation results to verify the operation of our algorithm. Ad-hoc Networking, Distance Vector
