Abstract:
Wireless Ad-Hoc networks are collections of nodes that communicate without any
fixed infrastructure. A critical problem in Ad-Hoc networks is finding an efficient and
correct route between a source and a destination. The need for scalable and efficient
protocols, along with the recent availability of small, inexpensive low-power positioning
instruments justify adopting position-based routing protocols in mobile Ad-Hoc networks.
This paper presents an overview of the existing Ad-Hoc routing protocols that make
forwarding decisions based on the geographical position of a packet's destination. We also
outline the main problems for this class of routing protocols. We conclude our findings by
discussing opportunities for future research.
