- Decentralization: Distributes file sharing across a network of peers, reducing strain on centralized servers and bandwidth costs.
- Resilience: Even if some peers go offline, others can continue sharing the file, ensuring robustness and reliability.
Disadvantages:
- Piracy Concerns: Often associated with illegal file sharing and copyright infringement, leading to legal and ethical challenges.
- Initial Seed Availability: Speed and availability of downloads depend on the number of initial seeders sharing the file.
- Security Risks: Users may inadvertently download malicious files or encounter security vulnerabilities in certain clients.
Main Strengths:
- Speed and Efficiency: Enables high-speed file sharing by distributing downloads across multiple peers, reducing reliance on centralized servers.
- Resilience: Even in the absence of centralized servers, BitTorrent ensures robustness and reliability by leveraging distributed peer-to-peer networks.
Mesh Networks
Mesh networks are decentralized networks where each node serves as a relay for data transmission. Unlike traditional networks that rely on centralized infrastructure, mesh networks can operate independently, making them resilient in areas with limited connectivity or during emergencies. P2P connections in mesh networks allow devices to communicate directly with each other, forming ad-hoc networks without relying on internet service providers. Mesh networks have applications in disaster recovery, rural connectivity, and IoT (Internet of Things) deployments.
Advantages:
