“…They define three types of messages: critical, disaster, and non-disaster, all classified using a lexicon of a real disaster scenario and keywords. Other characteristics of the message are used to differentiate them [24], where the authors prioritize message multicast over unicast, assuming that they may be more critical in disaster scenarios.…”

When disaster strikes, effective communication is crucial for emergency responses and accessing a victim's location. Using smartphonebased Delay Tolerant Networks (DTNs) is the prevalent proposed approach to work around network disruptions. One of the challenges in these networks is high-traffic congestion, since buffer limitation produces message drop before they are delivered. In this article, a congestion control strategy using message prioritization is presented for DTNs to increase network resilience facing high message congestion. We measure congestion considering the free space in the buffers of the nodes involved in the routing or by counting the messages deleted from the buffer in a fixed period to improve the availability and immediacy of information for disaster scenarios. We evaluated the proposed strategies using The ONE simulator to test different mobility models and communication protocols. Results show that the strategy improved delivery rate, buffer usage, eliminated messages, overhead, and latency for the highest priority messages. The best results were obtained in terms of latency, which fits our disaster scenario since timely information is vital. The trade-offs are a slightly lower average delivery rate and a decrease in the lowest priority message delivery rate.

“…Finally, the one that obtained better results was the approach called oblivious, which favors the latest messages in the system. An adaptive buffer division is proposed in [24] to prioritize a set of messages without producing starvation of the low-ranked messages.…”

The performance of wireless communication network is important in emergency rescue operations while ensuring optimum usage of limited wireless resources. Due to the disruption of normal wireless communication in a post-disaster scenario, the sustenance of an emergency communication network plays a significant role in relief operations. Under such a scenario, it becomes crucial to monitor the performance and reliability of the protocol in a time-bound manner. Some of the prominent challenges faced by the communication network during this period are related to energy efficiency, resources allocation, reliable connectivity, QoS, network throughput, and interoperability. A comprehensive performance appraisal of the emergency network considering the above-mentioned aspects is extremely important. This review provides a comprehensive survey of the widely used communication technologies applied for setting up an emergency communication network to mitigate the post disaster aftermath. The article also delivers an overview of the integration of new technologies with the existing standards for improving the performance of the disaster communication networks. Finally, we propose some promising solutions to overcome the limitations of existing emergency communication technologies to improve the overall network performance.

“…The oldest unicast message is deleted first, followed by the multicast message with a delivery ratio closest to the RMDA value whenever the free buffer is not enough to accommodate new messages. They further introduced a configurable delivery ratio to prioritize multicast messages and reserve a certain amount of buffer space for multicast messages only [49]. The scheme removes buffered messages based on an estimated number of group members, the number of ACKs, and the configured delivery ratio level.…”

The deployment of Internet of Things (IoT) applications in remote areas, such as environmental sensing areas, requires Disruption Tolerant Networking (DTN) support due to the lack of continuous network connectivity. IoT devices in DTN generate and store data until a network link is available for data transmission. Data mules or ferries are scheduled to travel among intermittent networks to collect data and disseminate configuration updates from control centers to all participating nodes in a reliable manner. The incorporation of efficient, reliable multicast algorithms into DTN helps to overcome the current limitations in updating large numbers of nodes in remote areas with identical configurations. In this paper, the current state of multicast routing protocols in DTN is outlined according to their design aspects. Open issues are also discussed to provide impetus for further research into the Reliable Multicast DTN (RMDTN) protocol.
