We propose a coherent optical and radio seamless network concept that allows broadband access without deployment of additional optical fibers within an optical fiber dead zone while enhancing network resilience to disasters. Recently developed radio-over-fiber (RoF) and digital coherent detection technologies can seamlessly convert between optical and radio signals. A millimeter-wave radio with...
In D3.1 the first concept for a WINNER radio network deployment mainly focused on relay based concepts are proposed. Further the concept of an radio and protocol architecture is presented that takes up the relaying approach as well as the idea of having different WINNER radio interface modes to serve different user and usage scenarios in an optimal manner. Thereby the presented protocol concept...
As the increased demands of wireless channel, there is the need for the proper utilization of the spectrum which leads us to the new technique called cognitive radio technologies. Static spectrum allocation need to merge with a technique where it can be share for the proper utilization of the spectrum. Higher capacity requirement is of great need. As long as the technology is been evolving the ...
We propose a novel randomized algorithm for computing a dominating set based clustering in wireless ad-hoc and sensor networks. The algorithm works under a model which captures the characteristics of the set-up phase of such multi-hop radio networks: asynchronous wake-up, the hidden terminal problem, and scarce knowledge about the topology of the network graph. When modelling the network as a u...
A multi-cluster, multi-hop packet radio network architecture for wireless adaptive mobile information systems is presented. The proposed network supports multimedia traffic and relies on both time division and code division access schemes. This radio network is not supported by a wired infrastructure as conventional cellular systems are. Thus, it can be instantly deployed in areas with no infra...
Five key UMTS radio network parameters are simultaneously optimized with an automatic control method. The parameters relate to admission control, power control, handover control, and coverage. The optimization is guided by heuristic expert-defined rules, which apply specific trade-off policies and statistics of poor quality calls, blocking rates, power and interference levels, and terminal meas...
The Rapidly Deployable Radio Network (RDRN) is an architecture and experimental system to develop and evaluate hardware and software components suitable for implementing mobile, rapidly deployable, and adaptive wireless communications systems. The driving application for the RDRN is the need to quickly establish a communications infrastructure following a natural disaster, during a law enforcem...
