In Mobile Ad hoc Networks, The route discovery mechanism utilize simple flooding method, where a mobile node massively rebroadcasts received route request (RREQ) packets until a route to destination is established. This can cause more retransmissions and thus excessive energy consumption. This work aims to reduce the number of messages RREQ (Route Request), by a new probabilistic and dichotomic method for the discovery of destination. This method can significantly reduce the number of RREQ packets transmitted during route discovery operation. Our simulation analysis can result in significant performance improvements in terms of energy. We propose a new probabilistic algorithm DRREQ (Dichotomic Route Request) which minimize significantly the energy consumption. Extensive simulations have been carried out for evaluation of the performance of our algorithm in different scenarios.
