Improvement Authentication of Routing Protocols for Mobile Ad Hoc Networks

Ad Hoc network Consist of mobile hosts ( or nodes ) which communicate with other nodes through wireless medium without any fixed infrastructure . Dynamic network topology : the mobile nodes are free to move randomly and organize themselves arbitrarily the wireless links in this network are highly error prone and can do down frequently due to mobility of nodes , interference and less infrastructure . therefore , routing in MANET is a critical task due to highly dynamic environment In recent years , several routing protocols have been proposed for mobile ad hoc networks ; to increase the secure path between the nodes . I focus on my scheme on authentication between the nodes and I choose Ad Hoc OnDemand Distance Vector ( AODV ) protocol to apply this scheme , which it depend on hash function , hash lock and random number generation , this scheme use to produce secure and authentication environment between the nodes In Mobile Ad Hoc Network.
