Abstract
A wireless mesh is used to collect data such as from a seismic survey. Data is collected at sensor nodes and transmitted in packets to aggregator nodes, where they are aggregated and transmitted to a central controller or a processing node for processing, in which the data is recorded on a storage device. Packets and aggregate packets may be compressed, encrypted and have wrappers applied, and these steps may be reversed in processing. The central controller distributes packets to multiple processing nodes for processing in parallel.
Claims23
A method of processing an aggregate packet of a stream of aggregate packets, the aggregate packet formed by aggregating plural data packets, the method comprising:
- a controller selecting a processing engine of a set of processing engines and causing the aggregate packet to be sent to the selected processing engine;
- processing the aggregate packet at the selected processing engine to recover the plural data packets;
- and
- processing the plural data packets at the selected processing engine by appending each of the plural data packets to a respective file on a respective file storage device.
A method of aggregating data, comprising:
- receiving at an aggregator plural data packets from plural source nodes;
- forming an aggregate packet at the aggregator by combining the plural data packets;
- and
- transmitting the aggregate packet from the aggregator to a central controller.
A method of transmitting and recording data packets produced at plural source nodes, the method comprising:
- arranging plural nodes including the plural source nodes into a mesh;
- configuring the plural nodes of the mesh to relay data packets from the plural source nodes to a central controller;
- the central controller sending each data packet to a respective processing engine;
- and
- at the respective processing engine processing each data packet by appending it to a respective file on a respective file storage device.
A method of transmitting and recording data packets produced at plural source nodes, the method comprising:
- arranging plural nodes including the plural source nodes into a mesh;
- configuring the plural nodes of the mesh to relay data packets from the plural source nodes to plural processing nodes;
- and
- at the respective processing engine processing each data packet by appending it to a respective file on a respective file storage device.
