hi friends,i m trying to simulate a route invasion attack in aodv. i changed
the recieve rreq packet routine keeping in mind that node=5 attacker node =0
source node =4 destination. total nodes=7.in this attack node 5 will modify the
rreq packet and rebroadcast it again. but in simulation node 5 is not running
this routine. can't figure out why. plz help me.all nodes will follow normal
aodv.cc routines. but attacker will also follow this routine.implementation is
done in the same aodv.cc file./* * Can't reply. So forward the Route
Request */ else if (index==5){if ((rq->rq_src ==0) && (rq->rq_dst == 4))
{ ih->saddr() = index; ih->daddr() = IP_BROADCAST; rq->rq_bcast_id =
rq->rq_bcast_id+5; rq->rq_hop_count += 1; // Maximum sequence number seen
en route rq->rq_src_seqno = rq->rq_src_seqno+6 ; if (rt)
rq->rq_dst_seqno = max(rt->rt_seqno, rq->rq_dst_seqno)+6; else
rq->rq_dst_seqno=
rq->rq_dst_seqno+6; forward((aodv_rt_entry*) 0, p, DELAY);
}}
else { ih->saddr() = index; ih->daddr() = IP_BROADCAST; rq->rq_hop_count
+= 1; // Maximum sequence number seen en route if (rt) rq->rq_dst_seqno =
max(rt->rt_seqno, rq->rq_dst_seqno); forward((aodv_rt_entry*) 0, p, DELAY); }
