ROUTENAUSWAHL IN EINEM ZELLULAREN MEHRSTROMNETZWERK

摘要

An 802.11 wireless network is disclosed which operates as an asymmetric two-hop cellular network. Relaying from one wireless node (18) via another wireless node (14) to an access point is enabled. The relays are limited so that a maximum of two-hops are used in uplink communications between the nodes (14,16,18,19) and the access point (12). Each node requiring a relay service advertises this to nodes close to it, other nodes respond if prepared to offer a relay service. The access point (12) receives those responses which are useful and selects a relay node (14) on the basis of data it holds about its links to the wireless devices (14, 16, 18, 19) in the network.
