A multi-hop wireless network for transmitting data packets between a concentration point (CP) and one of a plurality of radio transceiving nodes (e.g. R1....R6, Y1.....Y4) is described. Each node is allocated to a particular region which is spatially positioned relative to the concentration point (CP) such as a base station. The allocation of each node to a particular region may be carried out according to the distance of the node from the concentration point (CP), by distance measurements carried out by the node itself or by the concentration point (CP), or may be allocated according to the node's position (e.g. using GPS signals). Each node is correspondingly tagged according to its allocated region. Data transmission, for data to be transmitted from a particular node to the concentration point (CP) or in the reverse direction, is carried out according to predetermined rules, and in accordance with these rules each node receiving data for onward transmission may be constrained to transmit the data only to a node in the adjacent region. |
