Summary
The HARE protocol stack enables multi-hop communications in low-power wide area networks (LPWANs), achieving up to 15% energy savings. This new approach enhances scalability and device self-organization for the Internet of Things (IoT).
Area of Science:
- Computer Science
- Electrical Engineering
- Networking
Background:
- Low-power wide area networks (LPWANs) are crucial for the Internet of Things (IoT).
- Traditional single-hop LPWANs face scalability and energy efficiency challenges in dense deployments.
- Existing LPWANs often neglect device self-organization and resilience.
Purpose of the Study:
- To introduce the HARE protocol stack as an advanced LPWAN technology.
- To enable flexible uplink multi-hop communications in LPWANs.
- To improve energy efficiency and scalability in IoT networks.
Main Methods:
- Development and proposal of the HARE protocol stack.
- Implementation of uplink multi-hop communication capabilities.
- Validation through a real-world testbed and network device manipulation.
Main Results:
- Achieved energy savings of up to 15% using the multi-hop approach.
- Maintained network reliability comparable to single-hop deployments.
- Demonstrated system self-organization and resilience through association mechanism iterations and device failures.
Conclusions:
- The HARE protocol stack offers an energy-efficient and scalable solution for LPWANs.
- Multi-hop communication in LPWANs significantly reduces energy consumption.
- The HARE protocol stack enhances IoT network robustness and self-management.

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

3.6K
Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.

A coplanar force system refers to a set of forces that all lie in the same plane and are subject to different reactions between the point of contact and the supports. Understanding how different types of supports affect coplanar forces is crucial for designing safe and reliable structures that can withstand external loads.
The purpose of the supports is to prevent the translational motion of the system by applying an equal and opposite force and to prevent the system's rotation by applying...
