Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) system is targeted to efficiently guarantee the quality of service (QoS) of services such as audio/video streaming, gaming and Voice over IP (VoIP). So the system resource allocation should obtain the multi-user diversity gain making full use of the channel condition, and take the quality(More)
In this paper, we propose MWTP (Multi-hop Waiting Time Priority) scheduler to guarantee proportional delay differentiation in a multi-hop wireless network with contention- based MAC protocol. The existing single-hop delay differentiation schedulers can not differentiate the contention delay suffered at multi-hop links, and whole delay differentiation(More)
In this paper, we propose dynamic resource allocation with spatial reuse to improve total system throughput in multi-user system and multi-hop communication. The comparison of optimal and heuristic reuse scheme shows the heuristic reuse scheme is still good enough with low complexity. The simulation result shows that dynamic resource reuse scheme among(More)
Network Mobility (NEMO) supports the movement of some part of network that a group of Mobile Nodes (MNs) or Mobile Routers (MRs) moves together. To support NEMO, the NEMO basic support protocol (NBSP) was proposed [1]. In the nested mobile network, however, the NBSP exhibits pinball routing problem. The More nesting level, the problem becomes more serious.(More)
