The wireless channel is time-varying where burst packet losses often occur during the fading or lossy handovers. In order to avoid unaccepted quality degradation of video streamin...
We present QoS Geometric Broadcast Protocol (QoSGBP), a novel broadcasting protocol for heterogeneous wireless ad hoc and sensor networks. While broadcasting is a very energy-expe...
We propose a cooperative-diversity technique for ad hoc networks based on the decode-and-forward relaying strategy. We develop a MAC protocol based on slotted ALOHA that allows ne...
This paper describes an agent-based architecture that extends personal mobility to ubiquitous environment. A software agent, running on a portable device, leverages the existing se...
— Third Generation (3G) Mobile Communication systems will provide enhanced high-speed data, multimedia, and voice services to mobile users. Beam forming techniques have been prop...
