Frame retransmission using a modified VST-TDMA access protocol in Picocell/WPAN
(2017 IEEE 9th Latin-American Conference on Communications (LATINCOM)2017 IEEE 9th Latin-American Conference on Communications (LATINCOM), 12/28/2017)
The VST-TDMA access protocol has shown to have many advantages over existing protocols in centralized (star) wireless network architectures. As most data-link layer protocols, it does not have a recovery feature as data ...
State-of-charge estimation to improve energy conservation and extend battery life of wireless sensor network nodes
(2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN)2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN), 07/27/2017)
Wireless sensor networks are pervasive systems that continuously demonstrate increase in growth by branching into diverse applications. The state of charge is an indicator that conveys the amount of energy available in the ...
Lithium-ion battery pack arrays for lifespan enhancement
(2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 12/21/2017)
Depending on the application, power and energy requirements may differ significantly and, most likely, a single lithium-ion cell will not suffice. Battery packs offer cell interconnections that allow to obtain several ...
Improvements of Energy-Efficient Techniques in WSNs: A MAC-Protocol Approach
(IEEEIEEE, 10/12/2018)
The pervasiveness of wireless sensor networks (WSNs) across different applications keeps increasing due to their versatility, although energy consumption is a huge constraint for these types of networks. Therefore, it is ...
Spatio-temporal probabilistic modeling based on Gaussian mixture models and neural gas theory for prediction of criminal activity
(Annual Conference of the Prognostics and Health Management Society 2017Annual Conference of the Prognostics and Health Management Society 2017, 2017-08-18)
Criminal risk models are used to assist security forces both in the identification of zones with high of criminal activity for better resource allocation and prediction of future criminal events for the prevention of new ...
Modelling the degradation process of lithium-ion batteries when operating at erratic state-of-charge swing ranges
(2017 4th International Conference on Control, Decision and Information Technologies (CoDIT)2017 4th International Conference on Control, Decision and Information Technologies (CoDIT), 11/09/2017)
Manufacturers of lithium-ion batteries inform capacity degradation for regular, symmetrical charge/discharge cycles, which is clearly problematic in real life applications where charge/discharge cycles are hardly regular. ...
Electric Bicycle Energy Management Given an Elevation Traveling Profile
(Annual Conference of the Prognostics and Health Management Society 2017Annual Conference of the Prognostics and Health Management Society 2017, 2017-09-06)
This research proposes a method for energy management in electric bicycles with Lithium-Ion batteries. This method optimizes the way energy is consumed to maximize the rider’s comfort, subject to constraints on the battery ...
Characterization of the degradation process of lithium-ion batteries when discharged at different current rates
(05/08/2018)
The use of energy storage devices, such as lithium-ion batteries, has become popular in many different domains and applications. Hence, it is relatively easy to find literature associated with problems of battery state-of-charge ...
