This paper focuses on the problem of the exponential stability for a class of uncertain switched fuzzy (SF) delay systems. A switching control strategy is presented for a class of uncertain SF delay systems. A switched fuzzy delay system, which differs from existing ones, can often describe more precisely the fuzzy, continuous dynamics and discrete dynamics as well as their coupling and interactions...
Next generation wireless communication systems are expected to relay on integrated networks consisting of multiple wireless technologies. Heterogeneous wireless networks based, for instance, on systems such as WiMAX and TD-SCDMA can combine their respective advantages, offering a high Quality of Service (QoS) to mobile users. The vertical handoff decision is crucial to the integration of heterogeneous...
A new method based on Hilbert-Huang Transform (HHT) is proposed to analyze the blast vibration signal in this paper. Energy-frequency-time distribution of the signal can be established though EMD (empirical mode decomposition) and Hilbert transform, from which Hilbert energy spectrum is obtained. The energy spectrum is applied to indicate the energy distribution of the signal on the frequency axis...
In this paper we propose a new class of repetition- based MAC protocols for Vehicular Ad-hoc Networks. The design can be used for safety applications and position information dissemination. An erasure broadcast channel is considered in which several vehicles are in a cluster and each vehicle attempts to send its own safety message to all other vehicles. A distributed feedback mechanism has been introduced...
