Task 1: Heterogeneous Mesh Network Design: The mesh network will have three kinds of elements: Mesh Coordinator: the converging point of the heterogeneous network and maintains routing tables; Routers: which can talk other devices, and reduced function end devices (sensors): which can only talk to routers and the coordinator. The mesh Coordinators can be directly connected to the existing backbone of network of the mine or be standalone.
Task 2: Mesh Coordinator: The mesh coordinator will be developed with multiple antennas (WiFi, Zigbee, Bluetooth) with COFDM and a heterogeneous network convergence software module. This will essentially be a “black box” that can talk to Multiple wireless devices. This can be connected to the mine’s main power supply and/or a self-contained battery. This makes the device useable in mine rescue and recovery operations.
Task 3: Router and End Device: Development of a self-configuring/healing mesh algorithm with a suitable green communications technology for extending battery life in both prototype router and end devices.
Task 4: Prototype System Testing: Testing of the prototype will be conducted at our laboratory facilities at the University of Canberra. The developed communications system’s capability to communicate through ground obstruction will be tested practically and simulation.
Task 5: Analysis and Reporting: Results of the outcomes of the pilot project will be prepared and presented to Coal Services and used nt he ARC Linkage Grant application.
