In Mobile Ad hoc NETworks (MANETs), the network topology changes frequently and unpredictably due to the arbitrary mobility of nodes. This feature leads to frequent path failures and route reconstructions, which causes an increase in the routing control overhead. Effective routing protocol needed to developed or modifying existing one. Protocols can be divided into topology and position-based protocols but the protocol have physical position knowledge effective than others to overcome the unpredictably due to the arbitrary mobility of nodes.
