As wireless networks have been widely deployed for public mobile services, predicting the location of a mobile user in wireless networks became an interesting and challenging problem. If we can predict the next cell which the mobile users are going to correctly, the performance of wireless applications, such as call admission control, QoS and mobility(More)
Vehicular ad hoc networks technology is an important part of intelligent transportation system which has wide developmental and applied prospect. The routing protocol is a key technology of vehicular ad hoc networks and largely determines the performance of the vehicle network communication system. Vehicular ad hoc networks (VANETs) makes great requests to(More)
The IEEE 802.16 standard, also known as Worldwide Interoperability for Microwave Access (WiMax), which provides a mechanism for deploying high-speed wireless mesh networks in metropolitan areas. Thus, Quality of Service (QoS) is very important for WiMax networks. Providing QoS in multi-hop WiMax mesh networks is challenging as multiple links can interfere(More)
Due to the various kinds of business requirements, the next generation wireless network should be able to coordinate and integrate different communication systems. In this situation, predicting the location of a mobile wireless user is an inherently interesting and challenging issue. We propose a mobility prediction mechanism based on logistic cells(More)
Appling energy-shaping and port-controlled Hamilton (PCH) control principle, the model and control of the three-phase boost-type pulse-width modulated (PWM) AC/DC converters are presented in this paper. First of all, a PCH model of the three-phase PWM AC/DC converters is established in the d-q rotation frames. Then, according to the target of the controller(More)
As wireless networks are vulnerable to malicious attacks, security issues have aroused enormous research interest. In this paper, we focus on the anti-jamming power control of transmitters in a cooperative wireless network attacked by a smart jammer with the capability to sense the ongoing transmission power before making a jamming decision. By modeling the(More)
The IEEE 802.16 mesh network is a promising next generation wireless backbone network. In the mesh mode, the allocation of minislots is handled by centralized scheduling and distributed scheduling, which are independently exercised. However, the standard does not specify how the frame can be dynamically partitioned among its centralized and distributed(More)
IEEE 802.16 standard defines a broadband wireless access network technology, which provides a mechanism for creating multi-hop wireless mesh network. As multiple-access interference is a major limiting factor for the IEEE 802.16 mesh network, multi-channel transmission can eliminate the interference and improve the performance of the network. The efficiency(More)
