Today I want to introduce new method in energy saving strategy. It was focus on intermediate node, where each node rotating shift sleep mode due to prolong remaining energy. Here I show where we got 2 level of energy threshold value where 70% and 35% of remaining energy. Any intermediate node will change to sleep mode when 70% of remaining energy or level 1 threshold value accord. But if all intermediates node exceed level 1 threshold value, the threshold value itself will change to level 2 threshold value where until 35% of remaining energy. Then the same process apply to intermediate node.
