摘要
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.
