Abstract

An increasing number of applications based on Wireless Sensor Networks assume mobile environments(Mobile WSNs). Mobile WSNs propose several converging issues with Mobile Ad-hoc Networks (MANETs) but the peculiarities of their technology and application domain advise a specific theoretical analysis of mobility impact on network connectivity. Network performance depends by several factors; there is a clear relationship between overall performance and the efficiency of network mechanisms (e.g. topology control and routing) that are directly affected by network connectivity. The paper first proposes an evaluation of randomly deployed clustered WSNs in function of network size/density, topology and communication range. Then, the mobility impact on network connectivity is analyzed and evaluated extending the analysis to overlay configuration. This evaluation has an implicit relationship with mobile behaviors. In order to provide extended analysis capabilities, an analytic model for mobile behaviors is also proposed. All reported results were obtained through simulations according to a general approach, independent from routing protocols or any other domain specific mechanisms as well as by environmental conditions.
评估移动对无线传感器网络的影响
越来越多的基于无线传感器网络的应用在移动环境下进行。移动wsn提出了与移动自组织网络(manet)融合的几个问题,但其技术和应用领域的特殊性要求对移动性对网络连接的影响进行具体的理论分析。网络性能取决于几个因素;总体性能和网络机制(例如拓扑控制和路由)的效率之间存在明显的关系,它们直接受到网络连接的影响。本文首先从网络大小/密度、拓扑结构和通信范围等方面对随机部署的聚类wsn进行了评价。然后,将分析扩展到覆盖配置,分析和评估了移动性对网络连通性的影响。这种评价与移动行为有着隐含的关系。为了提供扩展的分析能力,还提出了一种移动行为分析模型。所有报告的结果都是根据一般方法通过模拟获得的,不受路由协议或任何其他特定于领域的机制以及环境条件的影响。
