Contiki cooja simulator steps for RPL based neighbor discovery
Description:In RPL requires to maintain a parent set and a candidate neighbour set.It storing information about those nodes that contribute to the routing topology.This helps the node to determine the neighbors in to select the best upon to completion of Neighbor Discovery.
Step-1
Open a file in a location to modify.
Contiki / core / net / ipv6 / uip-ds6-nbr.c
Here the neighbour related functions handling.
Code:
int uip_ds6_nbr_num(void)
{
uip_ds6_nbr_t *nbr;
int num;
num = 0;
for(nbr = nbr_table_head
(ds6_neighbors);
nbr != NULL;
nbr = nbr_table_next
(ds6_neighbors, nbr)) {
num++;
}
return num;
Step-2
Open cooja network simulator.
In terminal, go to the directory cd “contiki / tools / cooja /”
Give Command : ant run
In simulation control panel click start to run the simulation.
