The Energy consumption is a great challenge in the field on Wireless Sensor Network (WSN).It affects the performance of the whole network.There are two basic functions of nodes in the WSN.First is to collect the information from other sensor nodes and second is to pass the information to the base station.A variety of routing protocols have been proposed to reduce the energy consumption of nodes and increase the network lifetime.One of the most popular energy efficient routing protocol is Geographic Adaptive Fidelity (GAF).This is the location based routing protocol which uses the nodes location information to transfer the data.This reduces the use of energy by turning off the radio of some nodes which share the same functionalities.This paper focuses on the GAF protocol and its working.Also this paper reviews the variety of new versions based on GAF protocol to make it better.
