[ns] ARP drop packets in AODV, SRD 5/23/99

[Ko Chun Ho, Dennis]

Dear all,

I have changed the code of aodv.cc in ns2.26 and I found that there are 
a lot of ARP packet drop after running a simulation.
I think it may be due to the delay of packets forwarding as sometime I 
chanaged the delay of some forwarding pakcets, ARP packet drop disappears.
Also, I have read a commnet in aodv.cc as follows

....
....
                     Packet *buf_pkt;
                      while((buf_pkt = rqueue.deque(rt->rt_dst))) {
                         if(rt->rt_hops != INFINITY2) {
                             assert (rt->rt_flags == RTF_UP);

                             // Delay them a little to help ARP. 
Otherwise ARP
                            // may drop packets. -SRD 5/23/99

                              forward(rt, buf_pkt, delay);
                                delay += ARP_DELAY;
...
...


that the delay of the forwarding packets is related to ARP packet drop.

However, I don't know the reason.
Would you mind to give me some advice in the matter of ARP packet drop?


Thanks,
