Thanks dear Dr Fersi Ghofrane.

First a dozen of pages are quite useful.

if the information to stored is less than you can also use existing table like neighbor table (NT) you can go to header file and can add additional variables to existing tables as well. for functions you can define that in header file for that particular protocol and can be used in .CC file

void nb_insertrssi(nsaddr_t id,double reqRxPr); //my own function declared in .h file

//my own function can be defined in .CC file

void

AODV::nb_insertrssi(nsaddr_t id,double reqRxPr) {

AODV_Neighbor *nb = new AODV_Neighbor(id);

assert(nb);

nb->nb_expire = CURRENT_TIME +

(1.5 * ALLOWED_HELLO_LOSS * HELLO_INTERVAL);

//chintan inserting rssi in neighbour

nb->rssi = reqRxPr;

printf("inserting into neighbour table\n");

printf("neighbour rssi=%e\n",nb->rssi);

LIST_INSERT_HEAD(&nbhead, nb, nb_link);

seqno += 2; // set of neighbors changed

assert ((seqno%2) == 0);

}
