The development of wireless technologies shows a trend to heterogeneous wireless network (HWN), which attracts extensive attention on the research. Compared with a real network environment, a simulation system not only reduces cost, but also provides reliable and quantitative basis. This paper presents the design and implementation of our simulation system in HWN based on NS3 (Network Simulator 3),...
In this paper, a priority-based bandwidth allocation in the context of heterogeneous wireless network is studied. By utilizing the mobile terminals with multi-homing capability, which simultaneously accesses bandwidth from different wireless network, a novel utility-based bandwidth allocation approach is introduced. An essential factor is the priority mechanism considering the services priority classification,...
Cooperative communication is an efficient technology to achieve high bandwidth demands and wide error-prone client coverage. However, the previous cooperative multicast protocols suffer from bandwidth-violation problem while selecting relay nodes, namely, the cooperative hidden route problem (CHRP) by distributed protocols in wireless multicast networks. In this paper, a novel relay selection algorithm...
A wireless distribution implementation of smart distribution network is presented in this paper, and this is commonly thought as one of the key technologies of Internet of Energy. Several communication technologies applied in the power distribution are analyzed, the wireless distribution network (WDN) is designed with the software defined network concept, and the control plane is used as a common...
