20110170443 | LINK SENSITIVE AODV FOR WIRELESS DATA TRANSFER - A method of improving signal quality in an ad hoc on-demand distance vector (AODV) mesh network, comprising detecting at a node the signal quality of a received AODV protocol message, comparing the signal quality of the received AODV protocol message to a threshold; and on detecting that the signal quality of the received AODV message is not above the threshold, dropping the received AODV message. Further, a method of improving AODV mesh operation by detecting at a node the signal quality of the RREQ messages received at that node; and dropping any RREQ messages for which the signal quality is not above a threshold. | 07-14-2011 |
20130016625 | WIRELESS MESH NETWORK AND METHOD FOR REMOTE SEISMIC RECORDING - A method of collecting data from wireless sensor units arranged in a mesh network is disclosed, 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 aggregating at least a portion of the acquired data received from the wireless sensor units within the respective sub mesh cluster into aggregated data; and each aggregator transmitting the aggregated data to a base node. A wireless mesh network for remote seismic recording is also disclosed, | 01-17-2013 |
20130316749 | WIRELESS DATA PIPELINE - System and method for retrieving data from distributed nodes using radio. Data is transmitted through a mesh of nodes to aggregators, and may be transmitted through a mesh of aggregators to higher level aggregators. High level aggregators are arranged in pipelines and configured to transmit and receive simultaneously to maximize information relaying capacity. | 11-28-2013 |
20140192709 | METHODS OF WIRELESS DATA COLLECTION - 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. | 07-10-2014 |
