Zusammenfassung:The invention relates to a seismic data acquisition device consisting of a wireless network comprising a first assembly of nodes, termed active nodes (100) of the network, and a second assembly of nodes, termed peripheral nodes (110) of the network. The active nodes communicate using a TDMA system, with at least one empty timeslot to allow the peripheral nodes to use Carrier Sense Multiple Access (CSMA) to communicate. All nodes may communicate directly with the concentrator (200) or may use multi-hop.
