Protecting the network layer in a mobile ad hoc network is an important research topic in wireless security. This paper describes our unified network-layer security solution in ad hoc networks, which protects both routing and packet forwarding functionalities in the context of the AODV protocol. To address the unique characteristics of ad hoc networks, we take a self-organized approach by exploiting full localized design, without assuming any a priori trust or secret association between nodes. In our design, …
