AODV (Ad hoc On-demand Distance Vector) routing protocol is popular in wireless Ad hoc network. In this paper, the authors describe the AODV operation, the design and the pitfalls left in the (AODV) routing protocol structure. This paper is meant to aid the knowledge about AODV and how they can improve AODV. The two issues are focused in this paper, viz. security and energy efficiency. Security have important role in delivering the information to the desired destination while energy efficiency creates an impressive step towards the new developments and improvements.
