We 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 enables an adaptive and efficient cost-aware routing strategy. Depending on the objective or message priority, applications can use...
Geographic face routing protocols planarize the connectivity graph of a wireless network in a distributed manner and forward packets on the resulted planar topology with high reliability and low overhead. A preferable face routing protocol should provide both guaranteed packet delivery and efficient routing paths, which requires a flexible face switch algorithm adaptive to the network complexity....
