Summary
This study introduces the Fuzzy Control Energy Efficient (FCEE) routing protocol for wireless mesh networks. FCEE enhances network lifetime and performance by optimizing path selection and reducing unnecessary packet forwarding, outperforming existing protocols.
Area of Science:
- Computer Science
- Network Engineering
- Wireless Communication
Background:
- Efficient routing is critical for communication system performance, especially in resource-constrained mobile ad-hoc networks.
- Existing routing protocols face challenges in optimizing path selection and managing node energy.
Purpose of the Study:
- To propose and evaluate the Fuzzy Control Energy Efficient (FCEE) routing protocol for wireless mesh networks.
- To enhance network lifetime, performance, and energy efficiency compared to existing protocols.
Main Methods:
- Developed the FCEE protocol by integrating the Ad-Hoc On-Demand Distance Vector (AODV) protocol with fuzzy logic.
- Implemented a memory-based channel with fuzzy logic to restrict unnecessary broadcast packets based on node energy.
- Conducted extensive simulations to compare FCEE with AODV and Intelligent Routing AODV (IRAODV).
Main Results:
- FCEE significantly improved reliability, link connectivity, and route lifetimes over AODV.
- Achieved higher average throughput (351.374 Kbps) compared to IRAODV (90 Kbps) and AODV (39 Kbps).
- Demonstrated superior energy efficiency with average energy consumption of 14 joules, versus 40 for IRAODV and 90 for AODV.
Conclusions:
- The FCEE protocol effectively addresses routing challenges in wireless mesh networks.
- Fuzzy logic integration with AODV enhances network lifetime, performance, and energy efficiency.
- FCEE presents a promising solution for future wireless communication systems.

01:21Distributed Loads: Problem Solving
647
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...

In the domain of radio communication, the significance of impedance matching must be considered. It is crucial to ensure the efficient transmission of signals between radio transmitters and receivers. Achieving this balance involves using impedance-matching circuits, with one fundamental configuration comprising a resistor, capacitor, and inductor.
The process of harmonizing these impedances begins with a clear understanding of the input and output signals. Once these signals are known, the...

Mesh analysis is a valuable method for simplifying circuit analysis using mesh currents as key circuit variables. Unlike nodal analysis, which focuses on determining unknown voltages, mesh analysis applies Kirchhoff's voltage law (KVL) to find unknown currents within a circuit. This method is particularly convenient in reducing the number of simultaneous equations that need to be solved.

Mesh analysis becomes simpler when analyzing circuits with current sources, whether independent or dependent. The presence of current sources reduces the number of equations required for analysis. Two cases illustrate this:
Current Source in One Mesh: The analysis process is straightforward when a current source is found in only one mesh within the circuit. Mesh currents are assigned as usual, with the mesh containing the current source excluded from the analysis. Kirchhoff's voltage law...

The maximum power flow for lossy transmission lines is derived using ABCD parameters in phasor form. These parameters create a matrix relationship between the sending-end and receiving-end voltages and currents, allowing the determination of the receiving-end current. This relationship facilitates calculating the complex power delivered to the receiving end, from which real and reactive power components are derived.
