  The stateless, low overhead and distributed nature of the Geographic routing
protocols attract a lot of research attentions recently. Since the geographic
routing would face void problems, leading to complementary routing such as
perimeter routing which degrades the performance of geographic routing, most
research works are focus on optimizing this complementary part of geographic
routing to improve it. The greedy forwarding part of geographic routing
provides an optimal routing performance in terms of path stretch. If the
geographic routing could adapt the greedy forwarding more, its performance
would be enhanced much more than to optimize the complementary routing such as
perimeter routings. Our work is the first time to do so. The aligned physical
coordinate is used to do the greedy forwarding routing decision which would
lead more greedy forwarding. We evaluate our design to most geographic routing
protocols, showing it helps much and maintain the stateless nature of
geographic routing.
