Summary
This study introduces a new protocol for wireless powered sensor networks (WPSNs) that enhances performance by prioritizing energy and data packets. The Composite Energy and Data First (CEDF) protocol significantly improves throughput and reduces packet loss and delay compared to existing methods.
Area of Science:
- Wireless communication networks
- Sensor networks
- Energy transfer protocols
Background:
- Wireless Powered Sensor Networks (WPSNs) face challenges in performance optimization.
- Existing Medium Access Control (MAC) protocols like Round Robin (RR) and Data First (DF) have limitations in handling both data and energy transfer efficiently.
- The doubly near-far problem affects the reliability of energy transfer in WPSNs.
Purpose of the Study:
- To propose and evaluate a novel Frequency Division Duplex (FDD)-based on-demand energy transfer protocol and an energy-aware MAC protocol for WPSNs.
- To enhance the overall performance of WPSNs by improving throughput, reducing data packet loss, and minimizing delay.
- To investigate and propose solutions for the doubly near-far problem in WPSNs.
Main Methods:
- Development of a composite energy and data first (CEDF) MAC protocol that prioritizes polling based on data and energy packet counts.
- Implementation of an FDD-based on-demand energy transfer protocol.
- Performance evaluation through simulations, comparing CEDF with RR and DF protocols.
Main Results:
- The proposed CEDF protocol significantly outperforms RR and DF protocols in terms of throughput, data packet loss rate, and delay.
- The on-demand energy transfer protocol combined with CEDF effectively addresses the doubly near-far problem in WPSNs.

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.

01:37Energy to Drive Translocation
2.1K
Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.

In an electrical system with a resistor, voltage and current signals facilitate the measurement of power and energy across the resistor. For a continuous-time signal, the total energy over a time interval is defined as the integral of the square of the signal's magnitude over that interval. Mathematically, this is expressed as:

The fast decoupled power flow method addresses contingencies in power system operations, such as generator outages or transmission line failures. This method provides quick power flow solutions, essential for real-time system adjustments. Fast decoupled power flow algorithms simplify the Jacobian matrix by neglecting certain elements, leading to two sets of decoupled equations:

1.3K
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules.

02:12Short-distance Transport of Resources
16.6K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.
