Disaster resilient communication for tunnels and bridges

In the last few years, we have witness many disasters which destroyed communication networks to the outside world. Wireless mesh network (WMN) is one of the best choices for establishing a network during disaster recovery. In most disaster area, the reliability of WMNs decreased rapidly due any unpredictable environment changes. The disruption of services are often introducing delay and dropping of important and live saving messages. Thus, it is desirable to have a disaster resilient network that can temporarily withstand one or multiple of failed mesh nodes. In this paper, we introduce Disaster Resilient Network (DRN) for tunnels and bridges that allows mesh clients to contribute and retain the connectivity of the network. In DRN, mesh clients are able to establish and participate in data forwarding. We demonstrated that DRN is able to retain the capacity of original network under number of mesh node failures.
