What is MANET? Explain types of MANET and discuss VANET in detail.
SOLUTION
What is MANET?
A Mobile Ad Hoc Network (MANET) is a type of wireless network where devices (called nodes) communicate with each other without relying on fixed infrastructure like routers or access points. Each node in MANET acts as both a host and a router, forwarding data for other nodes. MANETs are self-configuring, flexible, and dynamic, making them useful in situations like disaster recovery, military operations, and remote areas.
Types of MANET
Intranet-based MANET – Formed within a local organizational network to allow wireless communication among devices.
Vehicular Ad Hoc Networks (VANETs) – Used among vehicles and roadside units for intelligent transport systems.
Internet-based MANET – Provides access to the global internet through gateway nodes.
Military MANET – Used in defense systems for secure and fast communication in battlefields.
Sensor-based MANET – Connects sensor nodes for applications like environment monitoring and health tracking.
VANET (Vehicular Ad Hoc Network) – In Detail
A VANET is a special type of MANET designed for vehicles. It allows vehicles to communicate with each other (Vehicle-to-Vehicle, V2V) and with roadside infrastructure (Vehicle-to-Infrastructure, V2I).
Working of VANET
Vehicles are equipped with wireless communication devices.
When two vehicles are within range, they share information such as speed, traffic, and road conditions.
Roadside units (RSUs) act as gateways to provide internet access or relay information between vehicles.
Applications of VANET
Traffic Management – Prevents congestion by sharing traffic updates.
Safety Systems – Alerts drivers about accidents, roadblocks, or slippery roads.
Navigation Assistance – Provides real-time route suggestions.
Entertainment & Internet Access – Offers in-vehicle multimedia and connectivity.
Advantages of VANET
Improves road safety.
Enhances traffic efficiency.
Provides better driving experience with real-time data.
Challenges of VANET
High mobility of vehicles makes maintaining stable connections difficult.
Security and privacy issues due to open communication.
Requires large-scale deployment of roadside infrastructure.
