The catalytic conversion of greenhouse gases CH4 and CO2 constitutes an effective approach for alleviating the greenhouse effect and generating valuable chemical products. However, the intricate molecular characteristics characterized by high symmetry and bond energies, coupled with the complexity of associated reactions, pose challenges for conventional catalysts to attain high activity, product...
This paper studies and evaluates a WiMAX relay architecture and its protocols to support multicasting/ broadcasting service and to address several related design issues. Performance of a video application is evaluated in term of different QoS measures. Our results demonstrate that the proposed architecture is feasible for real implementation and in line with the PMP characteristics of WiMAX.
This paper evaluates the QoS performance of transporting voice using WiMAX MBS (multicast/broadcast service). Our results demonstrate that the proposed MBS architecture can address several design issues arising from the mobility of the relay stations and the mobile stations. The service architecture is feasible for voice transport in the WiMAX multi-hop network.
