| Abstract |
Large-scale seismic sensor networks can be deployed for instance to monitor and subtract gravity-gradient noise (as foreseen in the R&D programme for the Einstein Telescope, a future gravitational-wave observatory) or in the field of geological exploration, for instance to search for gas and oil reservoirs. These networks may comprise in the order of a million nodes. We aim to develop such networks in which the nodes are wireless. In this proposal, we want to develop and implement fault-tolerant and robust protocols and applications capable of handling the communication between the nodes and data aggregation centers for meshed networks, in which the nodes have an arbitrary, but fixed, position. These protocols should allow for time division medium access, and support schemes in which the individual nodes can switch off their radios for a large fraction of the time, as well as allow for replacement of any node present in the network (hot-swap) or extension of the network, without interrupting the operation. |
