The two table show that the proposed new frame format can effectively reduce the power consumption of the nodes. For example, the bridge node S1 is very close to the sink node gateway and therefore receives lots of frames, including those that are destined for S1 and those that are destined for other nodes. In the conventional method, such frames must be abandoned or fully analyzed before being transferred, increasing the power consumption of the bridge nodes. By using our proposed method, S1 obviously saves a lot of energy. As far as normal nodes are concerned, normal nodes that are divided into groups effectively reduces power consumption. Take T7 as an example. T7 is close to the network center where many frames pass by. In the conventional method, T7 is not designated as the receiving node but consumes lots of power. By using our proposed method, nodes can detect and immediately ignore those packets that are bound for other destinations, extending the lifetime of normal nodes in the network.
