Nist DSR model appendix 6
Description:
This field is a hidden field used for the simulation of the transmission range. This field
contains the transmitter node Object id, which is used in the receiver through the
dsr_in_transmission_range(…) function to compute the distance between the two nodes.
Reply Packet
This packet is used to return a route in response to a Route Request packet, and is defined
in the filename Dsr_Reply.pk.m.
Type SRC DEST Seq_Number RELAY Seg_left Size_Route
Node_0 Node_1 Node_2 Node_3 Node_4 Node_5 Node_6 Node_7
TR_Source Reply_From_Target
Field Type
Type: 8 bits integer
Description:
This field contains the type of the packet. Since the packet is a reply packet, this field
takes the value of the REPLY_PACKET_TYPE constant.
Field SRC
Type: 8 bits integer
Description:
This field is used to store the DSR address of the Route Reply packet initiator.
Field DEST
Type: 8 bits integer
Description:
This field is used to store the DSR address of the Route Reply packet's target node
(which is the Route Request initiator).
Field Seq_Number
Type: 8 bits integer
Description:
This field contains the same sequence number that the Route Request, source of this
Route Reply, has.
Field RELAY
Type: 8 bits integer
Description:
This field is used to store the DSR address of the next node that should receive the Route
Reply packet.
Field Seg_Left
Type: 8 bits integer
