- Vehicular Ad hoc Network (VANET) utilizes vehicles as nodes in a network to make a mobile network.
- Wireless Sensor Network (WSN) comprises of independent sensors to control the ecological activities.
Usages of Ad-Hoc network :
- Military – An ad hoc networking will give access to the army to maintain an network among all the soldiers, vehicles and headquarters.
- Personal area network (PAN) – It is a short range, local network where each nodes are usually related with a given range.

- Medical Application – It can use to monitor patient.
- Environmental Application – It can be used to check weather condition, forest fire, tsunami etc.
Problems : There are several problems that Ad Hoc network faces –
- Limited wireless range
- Packet losses
- Energy conservation because of limited batteries.
- Low-quality communications.
- Hidden-node problem creates collision if two device try to communicate with same receiver.
- Exposed-node problem.
- Lack of security
- Addressing and service discovery
