A Novel Scheme to Minimize Hop Count for GAF in Wireless Sensor Networks: Two-Level GAF

<div>Comparison of the routing scheme between GAF and T-GAF (a) In GAF, a sensor can forward the data packet to any sensors of its AGs, while (b) In T-GAF, a sensor can forward the data packet to any sensors of its NAGs, if they are in the transmission range.</div>
