A Propose to Enhance the AODV Routing Protocols´ Security of Ad hoc Networks

Mobile ad hoc networks possess the following features: open transmission medium, dynamic topology structure, acentric management and distributed cooperation, and so on. Therefore, Ad Hoc Networks have high practical value, while at the same time it is difficult for which to guarantee the routing security, which is the most important component of the entire network´s security, it is also a difficult problem to be solved completely. This paper analyzes the working principle of the AODV routing protocol, discusses the protocol´s main potential safety problems - the problem of the black hole, proposes an solution based on the test of the destination node according to the significant vulnerabilities of some typical solutions already in existence, which not only solve the problem of the black hole effectively, but also eliminate the significant vulnerabilities existing in the original propose fundamentally.
