Hybrid Approach to Recover From Double Link Failure Using Backup Path in Ad-Hoc Networks
Nodes in mobile ad hoc networks communicate with one another via packet radios on wireless multi hop links. Because of node mobility and power limitations, the network topology changes frequently. Routing protocols therefore play an important role in mobile multi hop network. Communications. Networks have the problem of link failure. Then Networks employ link protection to achieve fast recovery from link failures. While the first link failure can be protected using link protection, there are several alternatives for protecting against the second failure. This paper formally classifies the approaches to dual-link failure resiliency.
