移动Ad Hoc网络中移动性干扰的影响研究

Investigating the Effects of Mobility Metrics in Mobile Ad Hoc Networks

Mohsin Ur Rahman

摘要:

移动自组织网络(Mobile Ad Hoc Networks,MANDO)是由一组能够从一个位置移动到另一个位置的移动节点(Mobile Node,MN)组成的网络。这些网络因其独特的特征而被广泛识别,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,移动自组网中的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递数据。由于移动性和不断变化的网络拓扑结构,这些网络的性能显着影响的移动模型和路由协议的选择。我们的研究工作旨在评估移动性指标区分实体和组移动模型在移动自组网的影响。此外,我们展示了移动性指标和性能指标之间的相互作用。我们还调查如何有效的流动性指标,哪些指标可以清楚地区分实体和组的移动模型?我们进行了广泛的模拟,使用网络模拟器,ns-2.35,捕捉移动性指标以及不同的性能指标。仿真结果表明,移动性度量区分实体和组移动模型的效率。我们还获得了有用的移动性指标和性能指标之间的相互作用。本文提出的结果提供了新的见解移动性指标的变化在移动自组网。此外,我们的模拟结果揭示了更好地理解移动性度量之间的关系(例如,相对速度、节点度、网络分区等)和性能指标(例如,分组投递率、端到端延迟和归一化路由负载

英文摘要:

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
