The next generation of wireless systems (NGWS) will allow the integration of multiple radio access technologies (RATs). This integration will enable that much functionalities that were specific to each RAT to be jointly processed, increasing the cooperation degree. This work focuses on radio resource management (RRM) for NGWS, where a new RRM architecture is introduced. In this architecture, the RRM...
Road accidents have a dramatic social and economic impact on the society, a situation that fostered the research of mechanisms for increasing road safety. Many of these mechanisms require the ability of the vehicles to communicate among each other and/or with fixed road-side stations. Due to the inherent mobility constraints, wireless technologies play a central role in this type of applications....
WiMAX, as a Broadband Wireless Access technology for Metropolitan Area Networks, supporting fixed and mobile terminals, is very promising for Next Generation Networks. Emergency Services can also strongly benefit from WiMAX features, allowing the exploitation of novel application scenarios and business models. This paper presents a set of scenarios, such as Environmental Monitoring, Telemedicine and...
