Cooperative communication is a powerful technology combating fading in wireless medium. In contrast to conventional cooperation (CC) which allows the relay to simply process and forward what it has heard, network-coded cooperation (NCC) endows network coding capability with the relay, i.e., allows the relay to first encode the data it has received from(More)
— With the advance of wireless technology, wireless devices are capable of adjusting transmit power and physical (PHY) layer data-rate. In this paper, we investigate the problem of how to adjust the power level and the PHY rate in order to maximize the network throughput in wireless ad hoc networks. Solving this problem can help solve the problem of(More)
— Network-coded cooperation is a new communication paradigm that exploits spatial diversity by pooling distributed " communication " (relay) and also the distributed " computation " resources (coding) of different nodes in a network so as to increase wireless networks system performance. In this paper, we develop a Selective Network-Coded Cooperation (SNCC)(More)
This paper proposed an opportunistic network-coded cooperation (ONCC) scheme suitable for multiple unicast transmission pairs in a single-cell wireless network. In contrast to existing work related to network-coded cooperation where the relay always performs network-coding-and-forwarding to help those transmitting terminals, ONCC is opportunistic because(More)
The exchange of health information between patients and multiple stakeholders empowers digital home based self-care, which can deal with the challenge of increasing chronic disease prevalence. Cloud computing has the potential to provide a more imaginative long-term solution. However, concerns over pattern of data sharing, confidentiality of sensitive(More)
The short-cut nitrification (SCN) performance of an airlift reactor (ALR) was investigated under increasing bicarbonate condition. The sequential increase of bicarbonate from 2.5 to 7.0 g/L accelerated the nitrite accumulation and improved the NAP to 99 %. With the increase of bicarbonate dose to 11 g/L, the ammonium removal efficiency and the ammonium(More)
