Abstract:
1. A method of collecting data from wireless sensor units arranged in a mesh network, each wireless sensor unit having one or more sensors arranged on or below the ground surface for remote seismic recording, the method comprising: clustering the wireless sensor units into two or more sub mesh clusters, each sub mesh cluster having an aggregator assigned to the sub mesh cluster; acquiring data with the wireless sensor units by sensing one or more physical parameters; within each sub mesh cluster, each of the wireless sensor units transmitting the acquired data directly or indirectly to the respective aggregator; each aggregator processing the acquired data to produce processed acquired data of reduced transmission bandwidth requirements than the acquired data, the processing comprising determining a representative data set to transmit to the base node as aggregated data and producing from the acquired data from each wireless sensor unit respective data sets of offset values relative to the representative data set to transmit to the base node as part of the aggregated; and each aggregator transmitting the aggregated data to a base node by real-time streaming in packets.
