Abstract:
Wireless Ad-Hoc networks are collection of nodes that
can communicate without any fixed infrastructure. A
crucial problem in Ad-Hoc networks is finding an efficient
route between a source and a destination. The need for
scalable and energy efficient protocols, along with the
recent availability of small, inexpensive and low power
positioning instruments justify introducing position based
routing algorithms in mobile Ad-Hoc networks.
This paper presents an overview and a qualitative
comparison of the existing Ad-Hoc routing protocols that
make forwarding decisions based on the geographical
position of a packet's destination. We conclude our
findings by investigating opportunities for future research.
