Now-a-days, in the people's daily life, a wireless technology has been commonly used. There are various advantages of using wireless network but also there are lots of challenges to make a wireless network useful. Its energy consumption is a crucial challenge which affects the wireless network performance. Many routing protocols in Wireless Sensor Network (WSN) are used for the same purpose. In WSN, Geographic Adaptive Fidelity (GAF) is a location based routing protocol which transmits data on the basis of location information of destination node. It works in three phases i.e. discovery phase, sleeping phase and active phase.
