Bi-connectivity, k-connectivity and Multipoint Relays
Résumé
Multipoint relays were introduced to optimize flooding in ad hoc networks. They are also used to determine a sub-topology containing shortest paths in the OLSR routing protocol. We show that a generalized version of multipoint relays can be used to construct a sub-topology preserving bi-connectivity and more generally $k$-connectivity. Moreover, we show that the multipoint relay structure is intrinsic to any sub-topology with similar properties.
