The authors propose a new link metric called Normalized ADVance (NADV) for geographic routing in multihop wireless networks. NADV selects neighbors with the optimal trade-off between proximity and link cost. Coupled with the local next hop decision in geographic routing, NADV provides an adaptive and efficient cost-aware routing strategy. Depending on the objective or message priority, applications can use the NADV framework to minimize various types of link cost. In this paper they present efficient methods for link cost estimation and perform detailed simulations in diverse scenarios.
