Through this article, our technical professionals have highlighted the most significant keynotes about the Aodv routing protocol in network simulator 2.

Aodv Routing Protocol in Ns2

Ad hoc on demand distance vector (AODV) protocol in Ns2 is defined as the routing protocol for ad hoc mobile networks along with large number of mobile nodes.

• C++ code to handle Aodv route request

struct hdr_ip *ih = HDR_IP(p);

struct hdr_aodv_request *rq = HDR_AODV_REQUEST(p);

aodv_rt_entry *rt;

• C++ code to detect the neighbor using Aodv

AODV_Neighbor*

aodv_rt_entry::nb_lookup(nsaddr_t id)

{

AODV_Neighbor *nb = rt_nblist.lh_first;

 for(; nb; nb = nb->nb_link.le_next) {

   if(nb->nb_addr == id)

     break;

 }

 return nb;

}

• TCL code to define the Aodv protocol object

set val(ifq)      Queue/DropTail/PriQueue

set val(ifqlen)             50

set val(netif)  Phy/WirelessPhy

set val(mac)                Mac/802_11

set val(rp)       AODV

Run Aodv Routing Protocol in Ns2

To run the Aodv routing protocol in Ns2, we have to implement the following commands.

cd /home/research/Desktop/NS2_simulation

sudo ./ns Scenario-2.tcl
