This paper addresses the important issue of how to optimize the performance of the current mobile backhaul radio access network (RAN) infrastructure to cope with the growing and dynamic nature of the emerging data-centric mobile multimedia traffic and services. Specifically, this work proposes and devises a simple and cost-effective EPON-based dynamic multiservice RAN architecture that efficiently...
In this paper we described the generic design of software interoperability modules for vertical handover in wireless hybrid access networks. The proposed approach conforms to the IEEE 802.21 Media Independent Handover (MIH) standard and fits into our architecture for reconfigurable interoperability of wireless communication systems, RIWCoS. The next step of our work will be the implementation of concrete...
This contribution addresses the case when live packet-switched video is used to enrich circuit-switched speech calls in mobile telephony. Circuit-switched and packet-switched transmissions generally operate on completely different transmission paths resulting in different QoS in terms of delay and loss rates. In this case, video and audio data recorded at the same time are not multiplexed together...
Dedicated short range communication (DSRC) is the key component in intelligent transportation systems (ITS). The goal of this technology is to help driver and passengers getting multimedia services via wireless communication equipment during the movement of vehicle, so as to improve the traffic safety and enhance the transportation efficiency. The paper is focus on the DSRC baseband technical analysis...
In this article we propose a unified radio network architecture, broadband wireless multimedia (BWM), which integrates broadcasting service and broadband wireless access service at both the application and physical layers. A simple, flexible, and comprehensive radio resource management framework is developed for the unified radio network. It is shown that the proposed radio network architecture has...
