This paper introduces a novel framework of coordinated spectrum sensing in cognitive-radio-enhanced vehicular ad hoc networks (CR-VANETs). The proposed sensing coordination framework intends to initiate a graceful compromise between stand-alone and cooperative sensing by taking the best of the two while mitigating their respective disadvantages. With a sensing coordination node temporarily defined,...
The multicast mobile ad-hoc network (multicast MANET) is proposed for a sender sending packets to several receivers through a multicast session. Since members of a multicast group changes frequently, the issue of supporting secure authentication and authorization in multicast MANET becomes more critical than the network provided a fixed central authentication (CA) server. This work thus proposes a...
