After I try new energy routing strategy on my simulation environment that can give advantage on remaining energy. But then when I look at packet delay show that new strategy effected. It is because after one or two intermediate nodes in sleep mode where data from source node have to go through long way until reach access point. Here the result:

We can see 3 out of 5 nodes the new algorithm is better which is node1, node 2 and node 7 but two more nodes effected cause of new energy routing strategy. So now I need to fine another way that can improve in this problem...
