Humans value rewards less when these are delivered in the future as opposed to immediately, a phenomenon referred to as delay discounting. While delay discounting has been studied during the anticipation of rewards and in the context of intertemporal decision-making, little is known about its neural correlates in the outcome phase (during reward delivery) and their relation to personality. Pers...

Real-Time reliable multicast over a best-effort service network remains a challenging research problem. Most protocols for reliable multicast use repair techniques that result in significant and variable delay, which can lead to missed deadlines in real-time scenarios. In this paper we present a repair technique that combines forward error correction (FEC) with automatic repeat request (ARQ). T...

The integration of biomedical sensors with wireless network technology may have great potentials in medical applications. In this paper, we investigate the use of the IEEE 802.15.4 standard in an ECG monitoring sensor network and study the effects of CSMA/CA mechanism, number of network devices, sampling rates and transmitting cycles. The performance of the network is analyzed in terms of trans...

Biomedical sensors (BMSs) monitor the heterogeneous vital signs of patients. They have diverse Quality of Service (QoS) requirements including reduced collision, delay, loss, and energy consumption in the transmission of data, which are non-constrained, delay-constrained, reliability-constrained, and critical. In this context, this paper proposes a traffic priority-aware adaptive slot allocatio...

In this paper a new protocol is proposed for reducing the power consumption of the battery-powered terminals in a mobile computing environment. We exploit the fact that, in a mobile data network mobile terminals do not continuously receive data and therefore they need not continuously operate their receivers. Nevertheless, they need to periodically check their traffic condition, that is, whethe...

Imagine a network technology that routinely loses information, experiences variable and unpredictable delay in data delivery, and makes no distinction between applications with different communication requirements. Next, imagine that the use of this technology is growing exponentially and that, even as networks become increasingly congested, its applications are being extended to global-scale v...

For maximum conservation of energy in sensor networks, one of the most effective approaches
