Summary
A new routing algorithm, rSEM, optimizes industrial wireless sensor networks (iWSNs) by minimizing system entropy. This approach balances power consumption and delay, offering a novel strategy for next-generation iWSNs.
Area of Science:
- Computer Science
- Electrical Engineering
- Network Engineering
Background:
- Industrial wireless sensor networks (iWSNs) face challenges in optimizing routing for power consumption and delay.
- Existing routing algorithms often focus on single performance metrics, neglecting overall network efficiency.
Purpose of the Study:
- To introduce a novel routing algorithm, rSEM, for iWSNs guided by a system entropy measure.
- To optimize iWSN routing by minimizing system entropy, thereby improving overall network performance.
Main Methods:
- A system entropy measure is introduced to guide the routing algorithm (rSEM).
- rSEM utilizes a cluster iWSNs architecture, selecting cluster heads and member nodes based on system entropy.
- Cluster head selection uses traversal, while member selection employs a greedy algorithm to reduce complexity.
Main Results:
- The power consumption of iWSNs using rSEM is comparable to Dijkstra's algorithm in 2D and 3D scenarios.
- rSEM exhibits slightly higher delay compared to the LEACH protocol.
- The algorithm is suitable for networks sensitive to both delay and power consumption.
Conclusions:
- rSEM offers a new paradigm for iWSN routing, considering network topology for improved performance.
- The system entropy measure provides an effective way to balance power consumption and delay in iWSNs.
- rSEM enhances overall network performance beyond solely optimizing power or delay.

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

A living cell's primary tasks of obtaining, transforming, and using energy to do work may seem simple. However, the second law of thermodynamics explains why these tasks are harder than they appear. None of the energy transfers in the universe are completely efficient. In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy. Thermodynamically, heat energy is defined as the energy transferred from one system to another that...

An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy. Scientists refer to the measure of randomness or disorder within a system as entropy. High entropy means high disorder and low energy. To better understand entropy, think of a student’s bedroom. If no energy or work were put into it, the room would quickly become messy. It would exist in a very disordered state, one of high entropy. Energy must be...

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

01:20Entropy and the Second Law of Thermodynamics
3.0K
The second law of thermodynamics can be stated quantitatively using the concept of entropy. Entropy is the measure of disorder of the system.
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
