Mesh Network
A mesh network is a decentralized network topology where nodes (devices) connect directly, dynamically, and non-hierarchically to as many other nodes as possible to relay data. This creates a self-healing and resilient infrastructure that can efficiently route traffic through multiple paths, often used in wireless settings like Wi-Fi mesh systems, IoT deployments, and peer-to-peer networks. It eliminates single points of failure and can extend coverage without relying on a central hub.
Developers should learn about mesh networks when building scalable, fault-tolerant systems, such as in IoT applications where devices need to communicate reliably in dynamic environments (e.g., smart homes, industrial sensors). It's also crucial for creating decentralized applications, like in blockchain or peer-to-peer file sharing, where resilience and reduced latency are priorities, or in disaster recovery scenarios where traditional infrastructure is unavailable.
