In this paper, we present CENTER, a CENtralized Trust-based Efficient Routing protocol for wireless sensor networks (WSN). CENTER is a secure and efficient routing protocol that utilizes the powerful sink base station (BS) to identify and ban different types of misbehaving nodes that may interrupt or abuse the functionality of the WSN. In CENTER, the BS periodically accumulates simple local observations...
Key management (KM) and secure routing (SR) are two most important issues for Mobile Ad-hoc Networks (MANETs), but previous solutions tend to consider them separately. This leads to KM-SR interdependency cycle problem. In this paper, we propose an integrated KM-SR scheme that addresses KM-SR interdependency cycle problem. By using identity based cryptography (IBC), this scheme provides security features...
