Abstract
A method and apparatus for reliable wireless voice, data and location communication for deployment in underground, industrial and other hazardous environments using a wireless mesh network. The network includes protocol for dispatch operation, emergency operation, remote supervision, remote status, asset control, machine state of health and operational management. The architecture is based on localized clusters of autonomous nodes capable of ad hoc interconnection with nearby nodes and connection to gateway nodes. The resulting network is an ad hoc mesh topology comprised of fixed mesh nodes with approximately 50% coverage overlap between nodes. This provides a reliable communication network for mobile nodes carried by personnel and sensor nodes that are fixed or mobile that supports voice, data and tracking/situation awareness. Each cluster of nodes transfers digital voice and data to gateway nodes either directly or through multi-hop transactions.
