A security enhanced AODV routing protocol based on the credence mechanism

Ad hoc networks are characterized by open medium, dynamic topology, distributed cooperation and constrained capability. These characteristics set more challenges for security. Routing security is the most important factor in the security of the entire network. However, few of current routing protocols have the consideration about the security problems. This paper analyzes the potential insecurity factors in the AODV protocol. A security routing protocol based on the credence model is proposed, which can react quickly when some malicious behaviors in the network are detected and effectively protects the network from kinds of attacks and guarantees the security of ad hoc networks.
