241 Ad-Hoc Network Fundamentals
241.1 Overview
Ad-hoc networks are infrastructure-less, self-organizing wireless networks where devices communicate directly without access points or base stations. Every device can act as both an endpoint and a router, forwarding packets for others.
This comprehensive topic is covered in three focused chapters:
241.2 Learning Path
241.3 Quick Start
TipWhich Chapter Should I Read?
- New to ad-hoc networks? Start with Core Concepts and Characteristics
- Need to select a routing protocol? Jump to Multi-Hop Routing and Protocols
- Want practical examples and quizzes? Go to Applications and Practice
241.4 Key Concepts Preview
241.4.1 What Makes Ad-Hoc Networks Special?
| Feature | Ad-Hoc Network | Traditional Network |
|---|---|---|
| Infrastructure | None needed | Requires APs/towers |
| Setup | Instant, self-organizing | Pre-planned deployment |
| Failure tolerance | High (multiple paths) | Low (single point of failure) |
| Scalability | Limited (10-200 nodes) | High (thousands) |
241.4.2 Three Routing Paradigms
- Proactive (DSDV, OLSR): Maintains routes continuously - low latency, high overhead
- Reactive (DSR, AODV): Discovers routes on-demand - low overhead, discovery delay
- Hybrid (ZRP): Proactive within zones, reactive between - balanced approach
241.4.3 When to Use Ad-Hoc Networks
- Disaster response (no existing infrastructure)
- Military/tactical operations (rapid deployment)
- Sensor networks (forests, oceans, farms)
- Vehicle-to-vehicle communication
- Temporary events (concerts, construction sites)
