Mobile Ad Hoc Networks (MANETs) are formed by a collection of mobile nodes (MNs) that are capable of moving from one location to another location. These networks are widely identified by their unique characteristics such as lack of infrastructure, mobility and multi-hop communication. Unlike traditional (wired) networks, MNs in MANETs do not rely on any infrastructure or central management. Mobility allows MNs to move at different values of speed. Multi-hop communication is used to deliver data across the entire network. Due to mobility and changing network topology, the performance of these networks is significantly affected by the choice of mobility models and routing protocols. Our research work aims to evaluate the effects of mobility metrics on distinguishing between entity and group mobility models in MANETs. In addition, we demonstrate the interactions between mobility metrics and performance metrics. We also investigate how effective are the mobility metrics and which metrics can clearly distinguish between entity and group mobility models? We performed extensive simulations using network simulator, ns-2.35, to capture mobility metrics as well as different performance metrics. Simulation results reveal the efficiency of mobility metrics on distinguishing between entity and group mobility models. We also obtain useful interactions between mobility metrics and performance metrics. The results presented in this paper provide new insights into the variability of mobility metrics in MANETs. Furthermore, our simulation results reveal better understanding of the relationships between mobility metrics (e.g., relative speed, node degree, network partitions etc.) and performance metrics (e.g., packet delivery ratio, end-to-end delay and normalized routing load

研究移动性指标在移动 Ad Hoc 网络中的影响

移动自组织网络 (MANET) 由一组能够从一个位置移动到另一个位置的移动节点 (MN) 组成。这些网络因其独特的特性而被广泛识别，例如缺乏基础设施、移动性和多跳通信。与传统（有线）网络不同，MANET 中的 MN 不依赖于任何基础设施或中央管理。移动性允许 MN 以不同的速度值移动。多跳通信用于在整个网络中传送数据。由于移动性和不断变化的网络拓扑，这些网络的性能受到移动模型和路由协议选择的显着影响。我们的研究工作旨在评估移动度量对区分 MANET 中实体和组移动模型的影响。此外，我们展示了移动性指标和性能指标之间的相互作用。我们还调查了移动性指标的有效性以及哪些指标可以清楚地区分实体和组移动性模型？我们使用网络模拟器 ns-2.35 进行了大量模拟，以捕获移动性指标以及不同的性能指标。仿真结果揭示了移动度量在区分实体和组移动模型方面的效率。我们还获得了移动性指标和性能指标之间的有用交互。本文中提出的结果为 MANET 中移动性指标的可变性提供了新的见解。此外，我们的模拟结果揭示了对移动性指标（例如，相对速度、节点度、网络分区等）之间关系的更好理解。
