The introduction of the full paper reviews a number of papers in the open literature, points out what we believe to be their shortcomings, and then proposes the protocol research mentioned in the title, which we believe is better and is explained in sections 1 through 2. Their core consists of; "In this protocol, all nodes are classified hierarchically by the number of hops from the sink node. The routing process is started from the sink node by flooding the routing messages to the whole network. At last, DMDD builds routing tables for all nodes. DMDD ensures minimum hops and delays. " Theoretical analysis, as presented in subsection 2. 3, and simulation results, presented in Figs. 1 through 5 and analyzed by us, show preliminarily DMDD protocol provides indeed higher energy efficiency and reliability than the generally used DD protocol.%针对定向扩散路由在能效性和可靠性方面的不足,指出一种互斥多路径定向扩散路由DMDD(Disjoint Multipath Directed Diffusion)协议.DMDD将所有网络节点按距离汇聚节点的跳数分层,由汇聚节点启动路由发现流程,将路由消息逐层泛洪到每一个节点,最终为每一个源节点建立了互斥多路径路由表.这些互斥路径同时还保证了最小跳数和最小时延.理论分析和仿真结果表明,DMDD协议比定向扩散路由协议具有更高的能效性和可靠性.
