摘要：Vehicular Ad Hoc Networks (VANETs) have wide applications in practice, such as rescue, emergency operations and battlefield communications. Due to limited transmission range, each node has to seek assistance of its neighboring nodes to help relay the data to transmit to other nodes. The reliable neighbouring nodes are important for successful data transmission from source node to destination node. The early works providing reliable routing mainly rely on cryptographic tools to prevent malicious nodes from injecting false information into network. However, these reliable routing schemes are always coupled with prerequisites, such as authentication center, key management mechanism, which are not feasible in MANETs.

In this talk, two evolutionary trust-based routing schemes to prevent different routing disruption attacks, such as active black hole, passive black hole, and selfish nodes, will be presented. In the first scheme, a neighbourhood connectivity based trust scheme targeting on the active black hole attacks is proposed. In this scheme, every node is required to exchange neighbour information before route discovery, and then uses collected neighbour information to verify each received route reply message. In the second scheme, a trust-based routing scheme that emulates human cognitive process is proposed. The mobile nodes will exchange trust-level values and evaluate these values based on their own cognitive judgment. We have integrated our proposed trust-based routing schemes into DSR routing protocol and studied their performances under different adversarial network environments.
