The invention discloses a
mobile AD Hoc network self-adapting secure routing method based on reliability. The method comprises the following four major steps: step I, a source node transmits data packets; step II, an intermediate node forwards the data packets; step III, a destination node receives the data packets; and step IV, the data packets are transmitted and confirmed and reliability is updated. The method integrates
route discovery and
data transmission into a whole process, each node evaluates the reliability of adjacent nodes reaching the destination node through a response feedbackmechanism, and independently makes a
route decision according to reliability evaluation level, so that unreliable nodes are avoided and a reliable path is selected from a plurality of alternative paths, the method solves secure and reliable
data transmission and symmetrical secret key transmission while solving secure routing discovery problem, and improves the security and the adaptability of the network. Compared with an existing
AD Hoc network routing method, the method can
resist attack to a greater extent on the basis that higher expense is not needed, still has good restorability when anetwork size is changed, nodes rapidly moves and even
attack in a large scope exists and error of nodes exists, and is applicable to large-scale network with rapidly moving nodes. The method has a higher practical value and a wide application prospect in the technical field of
mobile AD Hoc network security.
