Abstract
A broadcast routing protocol and system for the efficient dissemination of control information in ad-hoc networks is disclosed. First, cost is assigned for each link and/or node in the network. In some aspects, cost is assigned using minimum inverse degree (MID-) or combined (C-) cost. Next, a graph-theoretic entity is computed at each node. In some aspects, this entity is Minimum Spanning Tree (MST) or Modified Minimum Weighted Node Cover. Finally, an appropriate packet forwarding protocol is used to forward control information. The present invention exhibits improved bandwidth consumption versus flooding and is robust in several node mobility scenarios.
