Geographical routing uses physical location for routing process and routing protocols are topology free and they can easily adopt the dynamic behavior of wireless ad-hoc networks. Routing protocols support various submissions ranging from mobility estimation and management through to unidentified routing and energy efficiency for QoS. Large networks use this routing in environment of awareness due to working with location data for routing judgments and thus represent an significant phase in the journey towards ever-present computing. Geographical routing protocols should have resource awareness in order to utilize the distributed resources efficiently. In this survey paper, we will discuss the various methods developed by researchers for resources aware routing and their efficient utilization.
