NS-2 (2.34) development in Linux.

You need to pass node id as an argument to this method. e.g. in aodv.cc withing rt_resolve() method, rt_print(0); This will print node 0's routing table at that time with file name as node_0 . void AODV::rt_print(nsaddr_t node_id) {     FILE * tmpFile;     char tmpFileName[50] = "node_";     char tmp[10] = "";     sprintf(tmp,"%d",node_id);     strcat(tmpFileName,tmp);        tmpFile = fopen(tmpFileName, "w");     aodv_rt_entry *rt;        for (rt = rtable.head(); rt; rt = rt->rt_link.le_next)     {         fprintf(             tmpFile,             "Node Id:%i Current time:%.4lf Destination:%i Next hop:%i No. of hops:%i Seq. No.:%i Route expire:%f Flags:%.4lf %d \n",             node_id, CURRENT_TIME, rt->rt_dst, rt->rt_nexthop, rt->rt_hops,rt->rt_seqno, rt->rt_expire, rt->rt_flags);     }     fclose(tmpFile); } All the Best!

I am assuming AODV protocol. In rtable.cc add below code trust_entry::trust_entry() {    //Initialize as per your need. } trust_entry::~trust_entry() {   //Deconstruct as per your need. } trust_entry* trust_store::trust_lookup( nsaddr_t node_id) {      trust_entry *rp = trusthead.lh_first;      for (; rp; rp = rp->trust_link.le_next) {              if (rp->node_id == node_id)                  break;      }     return rp; } void trust_store::trust_delete( nsaddr_t node_id) {     trust_entry *rp = trust_lookup(node_id);     if (rp)     {         LIST_REMOVE(rp, trust_link);         delete rp;     } } trust_entry* trust_store::trust_insert( nsaddr_t node_id, nsaddr_t prev_node,nsaddr_t next_node,int32_t trust_value) {     trust_entry *rp;     //assert(tr_lookup(dst_seq_no) == 0);     rp = new trust_entry;     assert(rp);     rp->node_id = node_id;     rp->prev_node = prev_node;     rp->next_node = next_node;     rp->trust_value = trust_value;     LIS
