Query: Delay based Duplicate Transmission Avoid (DDA) Coordination Scheme for
  Opportunistic routing   Since the packet is transmitted to a set of relaying nodes in opportunistic
routing strategy, so the transmission delay and the duplication transmission
are serious. For reducing the transmission delay and the duplicate
transmission, in this paper, we propose the delay based duplication
transmission avoid (DDA) coordination scheme for opportunistic routing. In this
coordination scheme, the candidate relaying nodes are divided into different
fully connected relaying networks, so the duplicate transmission is avoided.
Moreover, we propose the relaying network recognition algorithm which can be
used to judge whether the sub-network is fully connected or not. The properties
of the relaying networks are investigated in detail in this paper. When the
fully connected relaying networks are got, they will be the basic units in the
next hop relaying network selection. In this paper, we prove that the packet
delivery ratio of the high priority relaying nodes in the relaying network has
greater effection on the relaying delay than that of the low priority relaying
nodes. According to this conclusion, in DDA, the relaying networks which the
packet delivery ratios of the high priority relaying nodes are high have higher
priority than that of the low one. During the next hop relaying network
selection, the transmission delay, the network utility, and the packet delivery
ratio are taken into account. By these innovations, the DDA can improve the
network performance greatly than that of ExOR and SOAR.
