When designing DSR, we had to determine at what layer within When designing DSR, we had to determine at what layer within
the protocol hierarchy to implement ad hoc network routing. We the protocol hierarchy to implement ad hoc network routing. We
considered two different options: routing at the link layer (ISO considered two different options: routing at the link layer (ISO
layer 2) and routing at the network layer (ISO layer 3). Originally, layer 2) and routing at the network layer (ISO layer 3). Originally,
