Abstract

This paper introduces a new priority-aware routing protocol for mobile Ad-hoc networks to be utilized in emergencies, which is based on AODV. Mobile Ad-hoc networks find extensive use in various domains including military operations, environmental monitoring, healthcare, disaster response, smart transportation systems, unmanned aerial vehicles, and smart homes. During emergencies, communication can be severely restricted or even impossible due to the congestion of physical communication channels and unexpected technical failures in the infrastructure. Mobile Ad-hoc networks offer a solution to maintain continuous and reliable communication under such challenging conditions. In emergency scenarios, it is crucial for any node in the network to promptly deliver urgent messages to the intended destination, especially when certain nodes require ongoing active communication. The proposed routing protocol effectively addresses this requirement through its priority-aware mechanisms. The protocol ensures that nodes not involved in emergency tasks select the least congested route to prevent any delays or disruptions in the transmission of critical emergency data. This approach guarantees seamless communication for emergency nodes while allowing non-emergency nodes to communicate with each other as well. The study proposed in this paper introduces a new priority-aware routing protocol based on AODV for mobile Ad-hoc networks in emergencies. The packet transmission ratio of emergency nodes within the network is improved while maintaining the overall network performance unaffected. The adoption of proposed mechanisms to enhance performance does not necessitate an expansion in the size of data and control packets. These mechanisms do not inflict any supplementary latency or incur packet loss expenses on the network. The proposed protocol has been implemented and evaluated using ns-3 simulation software across various emergency scenarios. The results show that emergency nodes using the proposed protocol, achieve better packet delivery ratios compared to the original AODV, DSR, P-AODV, and AOMDV protocols, with improvements of 10.8%, 15.9%, 6.2%, and 5.9% respectively. This improvement in the packet delivery ratio for emergency data traffic is achieved without causing any disruptions in the overall network communication flow.

城域网中高效紧急数据传输的新型优先级感知路由协议
本文以 AODV 为基础,为移动 Ad-hoc 网络引入了一种新的优先级感知路由协议,可用于紧急情况下。移动 Ad-hoc 网络广泛应用于军事行动、环境监测、医疗保健、灾难响应、智能交通系统、无人机和智能家居等多个领域。在紧急情况下,由于物理通信信道拥塞和基础设施出现意外技术故障,通信可能会受到严重限制,甚至无法进行。移动 Ad-hoc 网络提供了一种解决方案,可在这种具有挑战性的条件下保持持续可靠的通信。在紧急情况下,网络中的任何节点都必须及时将紧急信息传送到预定目的地,尤其是当某些节点需要持续进行主动通信时。拟议的路由协议通过优先感知机制有效地满足了这一要求。该协议确保不参与紧急任务的节点选择拥堵最少的路由,以防止关键紧急数据传输出现任何延迟或中断。这种方法既保证了紧急节点的无缝通信,又允许非紧急节点相互通信。本文提出的研究介绍了一种基于 AODV 的新优先级感知路由协议,适用于紧急情况下的移动 Ad-hoc 网络。在保持网络整体性能不受影响的情况下,提高了网络内紧急节点的数据包传输率。采用建议的机制来提高性能并不需要扩大数据包和控制包的大小。这些机制不会对网络造成任何额外的延迟或数据包丢失费用。我们使用 ns-3 仿真软件在各种紧急情况下对所提出的协议进行了实施和评估。结果表明,与最初的 AODV、DSR、P-AODV 和 AOMDV 协议相比,使用拟议协议的紧急节点能实现更好的数据包传送率,分别提高了 10.8%、15.9%、6.2% 和 5.9%。紧急数据流量数据包传输率的提高不会对整个网络通信流造成任何干扰。
