Summary
The new OFQS routing protocol enhances Smart Grids by prioritizing data traffic based on application needs. This smart grid solution improves network performance and extends device lifespan.
Area of Science:
- Computer Science
- Electrical Engineering
- Network Engineering
Background:
- Smart Grids (SG) require efficient data routing and prioritization due to heterogeneous applications with varying needs.
- The current Routing Protocol for Low-Power and Lossy networks (RPL) lacks Quality of Service (QoS) differentiation suitable for SG demands.
- Existing RPL objective functions do not adequately address SG-specific requirements like latency, reliability, and energy efficiency.
Purpose of the Study:
- To propose and evaluate OFQS, a novel objective function for RPL designed to meet the specific QoS requirements of Smart Grids.
- To enhance data routing and prioritization in SG networks by considering multiple metrics.
- To improve the overall performance and lifetime of Smart Grid networks.
Main Methods:
- Developed OFQS, an objective function with a multi-objective metric incorporating delay, remaining battery energy, and dynamic link quality.
- Implemented OFQS within the RPL protocol to enable QoS differentiation for various SG applications.
- Tested the proposed OFQS approach on a real-world sensor testbed.
Main Results:
- OFQS demonstrated lower packet delivery latency compared to existing solutions.
- The proposed function achieved a higher packet delivery ratio, ensuring reliable data transmission.
- Experimental results indicated an extended network lifetime due to optimized energy management.
Conclusions:
- OFQS effectively provides Quality of Service differentiation for diverse Smart Grid applications.
- The proposed objective function optimizes routing decisions by considering critical network parameters.
- OFQS represents a significant improvement over standard RPL for Smart Grid communication networks.

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

01:25Routes of Drug Administration: Parenteral
2.9K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.

01:22Routes of Drug Administration: Overview
9.6K
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

1.8K
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

01:29Drug Delivery: Parenteral Route
1.7K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
