METHOD FOR MANAGING SINGLE CHANNEL SPATIAL REUSE IN THE PRESENCE OF POTENTIALLY DISRUPTIVE NODES IN A MOBILE AD-HOC NETWORK

摘要

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 neighbourhood, and determined by performing S-SLOT spatial reuse.

1. A method for managing the spatial reuse of slots in a mobile network comprising several nodes Ni, comprising a first sub-cycle and a second sub-cycle, said network comprising one or more Potentially Disruptive Nodes (PDN), said nodes Ni and PDN comprising a local table LT, a global table GT indicating the possible reusability of S-SLOTs, and a summary of the global table SGT adapted to determine which S-SLOTs in said second sub-cycle can finally be reused by the local node, said method comprising the interleaving of said two sub-cycles:
first sub-cycle, the normal S-cycle, where S-SLOTs are all assigned statically and where each node has one and only one S-SLOT allocation, 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 allocations being equitably shared in a 2-hop neighbourhood, and determined by performing S-SLOT spatial reuse.
