发布时间：2018-08-03 14:31
【摘要】：移动传感器网络是一种自组织网络,其连通性覆盖是进行准确网络评估和仿真的前提之一,核心就是设置合适的节点传输距离,否则会导致网络的不连通,进一步影响路由等网络协议的分析。针对随机路点模型下的移动传感器网络,分析了几何随机图模型中最小生成树最长边的长度和节点最小传输距离的关系。并进一步基于渐近性空间分布理论,分析了确保连通的移动传感器网络的最小传输距离,最后利用实验仿真的方法,对理论分析结果进行了验证。结果表明,当节点数量较大时,理论分析的结果和实验结果更加趋于一致。
[Abstract]:Mobile sensor network is a kind of self-organized network. Its connectivity coverage is one of the prerequisites for accurate network evaluation and simulation. The core is to set the appropriate node transmission distance, otherwise, it will lead to the disconnection of the network. Further affect the analysis of network protocols such as routing. The relationship between the length of the longest edge of the minimum spanning tree and the minimum transmission distance of nodes in the geometric random graph model is analyzed for the mobile sensor networks under the random path model. Furthermore, based on the asymptotic spatial distribution theory, the minimum transmission distance of the mobile sensor network with guaranteed connectivity is analyzed. Finally, the theoretical analysis results are verified by the method of experimental simulation. The results show that the theoretical analysis results are more consistent with the experimental results when the number of nodes is large.
