Summary
This study introduces the load Balanced and constant Stretch protocol for bypassing Multiple Holes (BSMH) for wireless sensor networks (WSNs). BSMH enhances network lifetime by 30% by optimizing routing path length, control overhead, and node load balance.
Area of Science:
- Computer Science
- Network Engineering
- Wireless Sensor Networks
Background:
- Wireless Sensor Networks (WSNs) face challenges in network lifetime due to routing inefficiencies, especially in networks with holes.
- Existing routing protocols often fail to holistically address factors influencing network longevity.
Purpose of the Study:
- To propose a novel geographic routing protocol, BSMH, for WSNs with holes.
- To enhance network lifetime by simultaneously optimizing routing path length, control packet overhead, and load balance.
Main Methods:
- Development of the load Balanced and constant Stretch protocol for bypassing Multiple Holes (BSMH).
- Theoretical analysis of BSMH efficiency.
- Extensive comparative evaluation against state-of-the-art routing protocols.
Main Results:
- BSMH significantly prolongs network lifetime by 30% compared to existing protocols.
- The protocol maintains a routing path stretch under 1.3.
- BSMH demonstrates superior performance in load balance and reduced control overhead.
Conclusions:
- BSMH is an efficient routing protocol for WSNs with holes, outperforming existing methods.
- The protocol effectively balances network lifetime, path length, control overhead, and load distribution.
- BSMH offers a promising solution for extending the operational life of WSNs.

17.3K
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.

Consider a single-phase, two-wire, lossless transmission line terminated by an impedance at the receiving end and a source with Thevenin voltage and impedance at the sending end. The line, with length, has a surge impedance and wave velocity determined by the line's inductance and capacitance.
At the receiving end, the boundary condition states that the voltage equals the product of the receiving-end impedance and current. This relationship is expressed as a function of the incident and...

01:21Distributed Loads: Problem Solving
1.0K
Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...

The provided content explores the behavior of traveling waves on single-phase lossless transmission lines. It begins with a single-phase two-wire lossless transmission line of length Δx, characterized by a loop inductance LH/m and a line-to-line capacitance C F/m. These parameters result in a series inductance LΔx and a shunt capacitance CΔx.

In electrical engineering, a lossless transmission line is characterized by a purely imaginary propagation constant and a resistive characteristic impedance. The ABCD parameters, which describe the relationship between the input and output voltages and currents, indicate an equivalent π circuit with an imaginary series impedance and a shunt admittance. This results in a transmission line that, when the product of the phase constant (beta) and the length of the line is less than pi, exhibits...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
