The P2P Wireless Network Applied in Real-Time Vehicle Navigation

The real-time vehicle navigation under wireless environment is difficult for practical use due to the bottleneck of the cellular network wireless bandwidth. We applied the P2P wireless network into the real-time vehicle navigation system, and that turns out to be sound in efficient data transfer. The data transfer strategies include data pre-downloading which aims to smooth the navigation map display, the downloading rate maximization which fully utilizes the peers´ resources and the transfer data minimization which we will discuss in our later papers. Further, Experiment is made to validate our analysis.
