Re: [ns] Accessing Energy state through routing agent

[Ahmad R Shahid <arshahid@yahoo.com>]

this was one way i used to access the enery level of
the nodes, by first including

#include "node.h"

Node *rt_thisnode;
    rt_thisnode =
Node::get_node_by_address(nb->nb_addr);
    if((rt_thisnode -> energy_model() &&
       
rt_thisnode->energy_model()->energy())>rt_energy) {
          rt_energy =
rt_thisnode->energy_model()->energy();
          rt_id = nb->nb_addr;
    }
