In this paper, we optimize the handover procedure in the fast handover for mobile IPv6 (FMIPv6) protocol by using the IEEE 802.21 media independent handover (MIH) services. FMIPv6 is used to enhance the performance of handovers in mobile IPv6 and its basic extension for network mobility (NEMO), i.e., the fundamental mobility management protocols used in(More)
Reliability and timely information delivery are mostly concerned in vehicular ad hoc networks (VANETs). In this paper, we propose a link Delay and Reliability constrained QoS routing algorithm (DeReQ) for multimedia communications in VANETs. A new link reliability mathematical model which considers not only the impact of the link duration but also the(More)
Companding transform is an efficient and simple method to reduce the Peak-to-Average Power Ratio (PAPR) for Multi-Carrier Modulation (MCM) systems. But if the MCM signal is only simply operated by inverse companding transform at the receiver, the resultant spectrum may exhibit severe in-band and out-of-band radiation of the distortion components, and(More)
Multimedia communications over vehicular ad hoc networks (VANET) will play an important role in the future intelligent transport system (ITS). QoS support for VANET therefore becomes an essential problem. In this paper, we first study the QoS performance in multi-hop VANET by using the standard IEEE 802.11e EDCA MAC and our proposed triple-constraint QoS(More)
In this paper, we propose a positioning system using super-resolution time of arrival (TOA) in IEEE 802.11a/g networks. The performance of the super-resolution TOA estimation methods with the Multiple Signal Classification (MUSIC)/noise eigenvalues (EV) and traditional cross-correlation algorithm are compared in a simulated indoor multipath environment.(More)
In this contribution, spatial coding diversity is combined with spatial multiplexing to get higher joint gains on ensuring both low error rate and high spectrum efficiency. A general mathematical model of joint spatial coding and multiplexing (JSCM) is proposed and analyzed. Optimal criteria and a suboptimal iterative algorithm on the design of JSCM are(More)
Wireless local area networks (WLAN) represent one of the most important technological improvements in recent years. How to develop the location-aware applications for WLAN users, especially in an indoor environment is a challenging problem. Location sensing is a key technology to support location-aware applications. In this paper, we propose a location(More)
FGF21 (fibroblast growth factor 21) is a recently described member of the FGF family. It has been previously demonstrated that FGF21 is a potent regulator of glucose homeostasis. To improve stability of FGF21 for better efficacy, a new form of recombinant FGF21 was generated by fusion of a full length FGF21 gene and the Fc fragment of human IgG4 with(More)
