To communicate within disaster scenarios, different devices/systems capabilities need to be cooperated with specific protocols. The key communication protocol should be interoperable with thoes systems and provide the solution for emergency services. The paper studies the hybrid network disaster recovery (HNDR) systems and classifies its communication scenarios and requirements. We Design a new networking protocol for the hybrid network, with ability to forward through different transport protocols, and copes with node mobility and node failure. The paper considers heterogeneous network disaster recovery scenario and proposes a cost effective and easy to deploy hybrid network emergency communication protocol (HNEC). This internetwork protocol is a specific model of the inter-domain messaging (IDM) protocol for emergency communications. The routing protocol procedure is similar to the reactive AODV procedure but is different in maintaining routes from unpredicted link breaks or node failure. A detailed simulation model with the designed network layer model is used to investigate network delivery rate and end-to-end delay performance. The performance results are analyzed using varying node load, mobility speed, and network size.
