Abstract

The advancement of wireless technology is increasing the demand for scarce spectrum. Cognitive radio ad hoc networks (CRAHNs) were proposed as a solution to spectrum scarcity which is also deployed in combat. However, military cognitive radio ad-hoc networks (MCRAHNs) are subject to destruction and frequent link breakages. The challenge with MCRAHNs routing is the timing-out of packets. This paper proposes the spectrum-aware transitive multi-cast on-demand distance vector (SAT-MAODV), optimised for throughput and delay. The relay nodes are selected based on zonal data and mobility. This is achieved through handshaking and sharing of location data. The nodes are expected to store location data of nodes encountered, which is used in routing and in determining the movement of the node. The mobility of military nodes is organised and structured, which simplifies routing. The SAT-MAODV was evaluated in network simulator 2 and the results show that the scheme is effective. UsingSAT-MAODV instead of xWCETT reduced routing path and node relay delay by at least 65% and 13% respectively, and increased achievable throughput by 31%. It also improved the delivery ratio by 9% while reducing latency by 27% in comparison with MARSA.

面向军用认知无线电 Ad Hoc 网络的频谱感知传递式按需路由协议

无线技术的发展增加了对稀缺频谱的需求。认知无线电特设网络（CRAHNs）作为解决频谱稀缺问题的方案被提出，并被部署在作战中。然而，军用认知无线电 ad-hoc 网络（MCRAHNs）会遭到破坏，链路也会频繁断开。MCRAHNs 路由面临的挑战是数据包超时。本文提出了频谱感知多播按需距离矢量（SAT-MAODV），对吞吐量和延迟进行了优化。中继节点根据区域数据和移动性进行选择。这是通过握手和共享位置数据实现的。节点应存储所遇节点的位置数据，用于路由选择和确定节点的移动。军事节点的移动是有组织、有结构的，这简化了路由选择。在网络模拟器 2 中对 SAT-MAODV 进行了评估，结果表明该方案是有效的。使用 SAT-MAODV 替代 xWCETT 可将路由路径和节点中继延迟分别减少至少 65% 和 13%，并将可实现吞吐量提高 31%。与 MARSA 相比，它还提高了 9% 的送达率，同时减少了 27% 的延迟。
