**9.3. Data packets**

In the data transmission process, upon receiving a data packet from the previous-hop identifier (PHID), an intermediate node *vx pathvi*,*vj* will set their next-hop based on the next-hop identifier (NHID) provided by the cluster-head in the routing decision update. Data packets will be formed of the transmitting node's node identifier (NID), originating sensor's identifier (SSID), request identifier (RID), and the following:


While transmissions from different clusters may be of different priorities, typically transmissions from a given sensor cluster all have the same priority at any given time. Hence, it is optional and configurable for the network scenario in question.
