In this work, we study the throughput of two-way relay channel (TWRC) with different automatic repeat-request (ARQ) strategies. Beyond orthogonal relaying, we propose two network-coded ARQ schemes, where the packets intended for different end terminals could be combined at the relay nodes. By considering the per-hop and end-to-end maximum number of transmissions constraint, we derive the closed-from...
With the increase in population and rapid urban sprawl in the major big cities in China, traffic monitoring in the inner-suburban areas is becoming an urgent problem to be solved. This paper proposes using cellular network for inner-suburban freeway traffic monitoring. Backgrounds of cellular network and wireless location technologies are firstly introduced. Related works including simulation tests...
With the rapid development of wireless location technologies, mobile terminals as probes have been regarded as a feasible and low cost method for real-time and wide-area city traffic information collection. If mobile probes deployed in the suburban areas, it will be a feasible supplementary way of real-time traffic information collection in China. This paper tries to investigate map matching problem...
