Abstract: A method is provided for managing the spatial reuse of slots in a mobile network comprising several nodes Ni, said network comprising one or more Potentially Disruptive Nodes (PDN), said nodes Ni and PDN comprising a local table, a global table, and a summary of the global table comprising the interleaving of two sub-cycles: a first sub-cycle, the normal S-cycle, where S-SLOTs are all assigned statically and where each node has one or only one S-SLOT allocation, a second sub-cycle, the improved S-cycle, where each node has one S-SLOT assigned statically, and where for all nodes except PDN nodes, one or more additional S-SLOTs is assigned dynamically when topology makes it possible, dynamic S-SLOT allocation being equitably shared in a 2-hop neighborhood, and determined by performing S-SLOT spatial reuse.

Abstract: A method for managing node communications in a mobile ad-hoc network is provided where at least a node in the said network performs the following steps: identifying if it is a Potentially Disruptive Node (PDN) or a non-PDN node, a PDN node being a node that has a number of connected 1-hop neighbor nodes greater than a predetermined value K; when the node is identified as a PDN node, selecting a subset of its 1-hop neighbor nodes, the selected nodes being the only 1-hop neighbor nodes that are allowed to communicate directly with the PDN node, the selected nodes being called Bridge Nodes (BN), non-BN nodes being called Regular Nodes (RN), the said RN nodes being able to communicate with PDN nodes via the selected BN nodes.
