在移动A d hoc网络研究中,路由协议的研究一直都是学术界广泛关注的焦点,围绕A d hoc网络的路由协议,已经开展了大量的研究工作,具有成果性的协议主要有DSR,AODV,DSDV和TORA。DSDV协议是运用在A d hoc网络上的一种先应式路由协议,以前文章对DSDV路由协议的研究主要侧重于协议本身的性能特点。文中在对DSDV全面理解的基础上,考虑到军事应用的特殊性和协议结构本身的特点,通过对协议进行部分改进使之在A d hoc网络内能够支持信息的一对多点传送。改进后的协议提高了信息的传输效率和网络的Q oS性能,同时也扩充了协议的功能。并用OPENT仿真软件对改进后的协议进行了分析和验证。 In the research of mobile A d hoc network, the research of routing protocol has always been the focus of academic interest. A great deal of research work has been carried out around the routing protocol of A d hoc network. There are mainly DSR, AODV , DSDV and TORA. DSDV protocol is a pre-emptive routing protocol which is used in A d hoc networks. Previously, the research on DSDV routing protocol mainly focused on the performance characteristics of the protocol itself. Based on the comprehensive understanding of DSDV and taking into account the particularity of the military applications and the characteristics of the protocol structure itself, the DSDV can support the one-to-many multi-point transmission of information in the Ad hoc network by partially improving the protocol. The improved protocol improves the transmission efficiency of information and Q oS performance of the network, and also expands the function of the protocol. OPENT simulation software was used to analyze and verify the improved protocol.
