The High Efficient in Three-dimensional UASN Based-on Geographic Routing

The existing protocols of geographic routing protocols have high transmission delay, the low delay of ABGR is proposed. This protocol based on the location of nodes, in the maximum transmission radius, according to the candidate forwarding node on the source node and destination node size of the projection value, with the minimum delay to send the packet to the destination node. The result of the simulation shows that the ABGR protocol reduce transmission delay at least 1.8% and improve the packet delivery ratio about 2.3% compare with other two protocols.
