Wireless adhoc network communication using failure insensitive routing for underground mines

The wireless ad-hoc network based on FIR (Failure Insensitive Routing) for the underground mining environment is to improve existing mining wireless network deficiencies. It is a proactive local rerouting based approach has the characteristics of interface specific forwarding, suppressing the link state advertisement and rerouting using a backwarding table when compare with OSPF (Open Shortest Path First Link State Routing Protocol). OSPF is a Proactive routing protocol and it does not provide flexibility in terms of packet forwarding to achieve any network optimization and causing significant forwarding discontinuity after a node failure. The drawback with this protocol is that they need off routing stability and forwarding continuity. To improve failure resiliency without routing stability we propose a FIR approach. In this paper, we prove that when a node in a network fails the FIR finds an alternate path to the destination during any disaster happens in the underground mining environment.
