Geographical routing is powerful for its ability to discover a path to the destination without the help of global states. However, stateless geographical routing usually involves a large number of hops when detouring around voids of the network. In this paper, we propose an efficient path pruning (PP) strategy to reduce the excessive number of hops caused by the detouring mode of geographical routing...
Geographical routing protocols are promising in wireless sensor networks because of their ability to discover a sub-optimal route without the help of a global state. Existing geographical routing protocols can guarantee packet delivery if the network topology after planarization remains connected. However, face routing used in non-flooding geographical routing algorithms usually results in a large...
