复合可重构Ad Hoc网络(英文)

Composite Reconfigurable Multi-Clustering Ad Hoc Network

随着众多无线通信网络标准的不断涌现,如何解决不同Ad Hoc网络之间互操作性差这一问题逐渐引起了各界的重视,此方面现有研究成果大都集中在重新设计MAC层协议或是链路选择协议上.本文提出了一种新的Ad Hoc网络结构,并解释了这一网络结构所采用的分簇算法、利用可重构终端实现优选物理链路的实现方案,用于解决互操作性差的网桥机制.针对这种全新的网络结构,文中还给出了基于Matlab的仿真平台的实现方法.仿真结果显示,这一新的网络结构可以在小幅增加网络平均时延的代价下提高全网络的数据包投递率.

With the emerging of numerous wireless network standards, the great obstacle of interoperability between various conventional ad hoc networks can not be ignored anymore. Most previous researches concerned with this problem are focusing on either MAC layer traffic or connection selection schemes. This paper presented a new ad hoc network structure, which contains an improved clustering algorithm, mobile terminals with reconfigurable The simulation results demonstrate that, the new physic layers and a Network Bridging mechanism. network structure can improve the delivery rate at a cost of a slightly worsen of network average delay.
