一种最小化移动Ad Hoc网络中移动节点恶意行为的新方案

A New Scheme for Minimizing Malicious Behavior of Mobile Nodes in Mobile Ad Hoc Networks

Syed S. Rizvi, Khaled M. Elleithy

摘要:

移动自组织网络的性能取决于所有活动节点的协作。然而,对于移动节点来说,支持MANET是一项成本密集型活动。从单个移动节点的角度来看,路由的检测以及转发数据包消耗本地CPU时间、内存、网络带宽,以及最后但并非最不重要的能量。我们认为,这是一个主要因素,强烈激励移动节点拒绝为他人的数据包转发,而在同一时间使用他们的服务,以提供自己的数据。独立移动节点的这种行为通常被称为行为不端或自私。大量的研究已经做了最小化移动节点的恶意行为。然而,他们大多集中在方法/技术/算法,从移动自组网中删除这些节点。我们认为,这种行为不端的节点的频繁消除从来没有允许一个自由和更快的增长的移动自组网。本文提供了一个批判性的分析,最近的研究工作和它的整体性能的移动自组网的影响。在本文中,我们澄清了一些误解的自私和错误的行为的节点的理解。此外,我们提出了一个数学模型,基于时间分割技术,以最大限度地减少移动节点的恶意行为,避免不必要的淘汰坏节点。我们提出的方法不仅提高了资源共享,但也创造了一个一致的信任和合作(CTC)的环境之间的移动节点。仿真结果表明,所提出的方法,显着减少恶意节点,从而最大限度地提高了移动自组网的整体吞吐量比其他众所周知的计划是成功的。

英文摘要:

The performance of Mobile Ad hoc networks (MANET) depends on the cooperation of all active nodes. However, supporting a MANET is a cost-intensive activity for a mobile node. From a single mobile node perspective, the detection of routes as well as forwarding packets consume local CPU time, memory, network-bandwidth, and last but not least energy. We believe that this is one of the main factors that strongly motivate a mobile node to deny packet forwarding for others, while at the same time use their services to deliver its own data. This behavior of an independent mobile node is commonly known as misbehaving or selfishness. A vast amount of research has already been done for minimizing malicious behavior of mobile nodes. However, most of them focused on the methods/techniques/algorithms to remove such nodes from the MANET. We believe that the frequent elimination of such miss-behaving nodes never allowed a free and faster growth of MANET. This paper provides a critical analysis of the recent research wok and its impact on the overall performance of a MANET. In this paper, we clarify some of the misconceptions in the understating of selfishness and miss-behavior of nodes. Moreover, we propose a mathematical model that based on the time division technique to minimize the malicious behavior of mobile nodes by avoiding unnecessary elimination of bad nodes. Our proposed approach not only improves the resource sharing but also creates a consistent trust and cooperation (CTC) environment among the mobile nodes. The simulation results demonstrate the success of the proposed approach that significantly minimizes the malicious nodes and consequently maximizes the overall throughput of MANET than other well known schemes.
