基于分簇的Ad Hoc网络媒体接入控制协议C-USAP
C-USAP: a media access control protocol based on clustering in Ad Hoc networks
摘要
Abstract
The future large-scale wireless Ad Hoc network,which is not only to ensure the efficient transmission of data,but also to ensure the network topology can adapt to the rapid changes.The existing Modified-Unifying Slot Assignment Protocol (M-USAP) can complete the interaction of the control information of the whole network in one frame,and each node has entire routing information of the network.Thus,M-USAP can quickly adapt to the changes of the network topology in the small-scale network.Nevertheless,with the increasing of the network's scale,there are some shortcomings such as large routing overhead,slow routing convergence,high end-to-end delay,low node throughout,slot reuse rate and slow network response.In view of the above problems,this paper proposes a Clustering-Unifying Slot Assignment Protocol (CUSAP) for large-scale Ad Hoc networks.The protocol is based on clustering technology,the dynamic time division multiple access protocol is adapted to inner-cluster communication and the multi-band segmentation technology is adopted to inter-cluster communication,which achieves the interaction of inner-cluster and inter-cluster.The simulation results show that this protocol has the characteristics of fast convergence of routing,smooth transmission and reception,low end-to-end delay,high slot reuse rate and network flexibility.关键词
