Overview
Direct Answer
A mesh network is a distributed topology in which nodes communicate directly with multiple peers rather than relying on a central hub, allowing data to traverse alternative paths when primary routes fail. Each participating device acts as both an endpoint and a relay, creating inherent redundancy and fault tolerance.
How It Works
Nodes maintain connections to two or more adjacent nodes and forward packets along available routes using routing protocols such as AODV or OLSR. When a direct path becomes unavailable, the network automatically reroutes traffic through alternate nodes without requiring manual reconfiguration. This self-healing capability emerges from the decentralised architecture where no single point of failure controls connectivity.
Why It Matters
Organisations deploy this topology to improve resilience in critical infrastructure, reduce latency in remote deployments, and decrease dependence on centralised infrastructure. Cost efficiency and coverage extension are drivers in environments where conventional backbone deployment proves impractical or prohibitively expensive.
Common Applications
Wireless sensor networks in industrial monitoring, emergency response communications in disaster zones, and extending coverage in buildings or campuses with dense obstacles represent established implementations. Military communications and smart city IoT deployments increasingly utilise mesh principles for robustness.
