Abstract

Opportunistic Mobile Ad Hoc Networks (MANETs) offer versatile solutions in contexts where the Internet is unavailable. These networks facilitate the transmission between endpoints using a store-carry-forward strategy, thereby allowing information to be stored during periods of disconnection. Consequently, selecting the next hop in the routing process becomes a significant challenge for nodes, particularly because of its impact on Quality of Service (QoS). Therefore, routing strategies are crucial in opportunistic MANETs; however, their deployment and evaluation in real scenarios can be challenging. In response to this context, this paper introduces a monitoring software-driven tool designed to evaluate the QoS of routing algorithms in physical opportunistic MANETs. The implementation and its components are detailed, along with a case study and the outcomes provided by an implementation of the proposed solution. The results demonstrate the effectiveness of the implementation in enabling the analysis of routing protocols in real scenarios, highlighting significant differences with simulation results: mobility patterns in simulations tend to be inaccurate and overly optimistic, leading to a higher delivery probability and lower latency than what is observed in the real testbed.

在真实设备上评估机会移动 Ad Hoc 网络路由算法的服务质量:软件驱动方法
机会移动特设局域网(MANET)为无法使用互联网的情况提供了多功能解决方案。这些网络采用存储-携带-转发策略促进端点之间的传输,从而允许在断开连接期间存储信息。因此,在路由过程中选择下一跳成为节点面临的一个重大挑战,尤其是因为它对服务质量(QoS)的影响。因此,路由策略在机会主义城域网中至关重要;然而,在实际场景中部署和评估路由策略却极具挑战性。针对这种情况,本文介绍了一种监测软件驱动工具,旨在评估物理机会主义城域网中路由算法的 QoS。本文详细介绍了该工具的实施及其组成部分,同时还介绍了一个案例研究以及实施该建议解决方案所取得的成果。结果表明,该实施方案能有效分析真实场景中的路由协议,突出显示了与仿真结果的显著差异:仿真中的移动模式往往不准确且过于乐观,导致与真实测试平台中观察到的结果相比,交付概率更高,延迟更短。
