On Maximizing Sensor Network Lifetime by Energy Balancing [PDF]

open access: yesIEEE Transactions on Control of Network Systems, 2017
Many physical systems, such as water/electricity distribution networks, are monitored by battery-powered wireless-sensor networks (WSNs). Since battery replacement of sensor nodes is generally difficult, long-term monitoring can be only achieved if the ...

Maximize the Coverage Lifetime of Sensor Networks [PDF]

open access: yes, 2006
When deploying sensors in the field in order to collect useful information, one of the most important issues is how to prolong the lifetime of the network because of energy constraint of the sensors while guaranteeing that every point in the network is covered.

Cross‐Scale Decoupling Kinetic Processes in Lithium‐Ion Batteries Using the Multi‐Dimensional Distribution of Relaxation Time

open access: yesAdvanced Science
To non‐destructively resolve and diagnose the degradation mechanisms of lithium‐ion batteries (LIBs), it is necessary to cross‐scale decouple complex kinetic processes through the distribution of relaxation times (DRT). However, LIBs with low interfacial

Dynamic energy balanced max flow routing in energy-harvesting sensor networks

open access: yesInternational Journal of Distributed Sensor Networks, 2017
We propose a dynamic energy balanced max flow routing algorithm to maximize load flow within the network lifetime and balance energy consumption to prolong the network lifetime in an energy-harvesting wireless sensor network.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Controlled Sink Mobility Algorithms for Wireless Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2014
A wireless sensor network (WSN) consists of hundreds or thousands of sensor nodes organized in an ad hoc manner to achieve a predefined goal. Although WSNs have limitations in terms of memory and processors, the main constraint that makes WSNs different ...
