What Is The Full Form Of MANET?
The full form of MANET is Mobile Ad Hoc Network.
MANET is a wireless network of decentralized type. It does not rely on an access point in the managed infrastructure or a pre-existing infrastructure, like routers in wired networks. It is, thus, ad hoc. MANETs are mobile, and they wirelessly connect to various networks. It can be any medium of connection, such as a standard Wi-Fi, satellite, or cellular transmission. MANET acts as a self-arrangement of mobile router networks that connect through wireless links (no access point).
Every device acts as autonomous in the Mobile ad hoc network. These mobile devices are free to move randomly while they organize themselves. Every node in MANET shares the wireless medium. The way in which the constituent parts interrelate with the network changes dynamically and irregularly. MANET frequently breaks communication links since the nodes move freely everywhere.
History of MANET
- You can categorize MANET into first, second, and third generations.
- The first-gen stood with PRNET (packet radio networks). DARPA sponsored it in the early 1970s.
- The second-gen came into the picture in the 1980s. It happened when the Survivable Adaptive Radio Networks (SURAN) significantly improved upon the scalability of algorithms, radios, and elasticity/flexibility to electronic attacks.
- Various other developments during this period include NTDR ( Near Term Digital Radio) and GloMo (Global Mobile Information System).
- The third gen came in the 1990s when open-source software, notebook computers, and tools based on RF and infrared arrived. This network acted as a commercial network.
Application Areas of MANET
- SPANs (Smartphone ad hoc networks)
- VANETs (Vehicular ad hoc networks)
- Wireless mesh networks
- Army tactical MANETs
- Navy ad hoc networks

- Data mining and monitoring
- Police exercises
- Urgent business meetings
- Disaster relief operations
- Personal area network
- Mine site operations
Benefits of MANET
- The network is always high-performing.
- MANET follows a router-free internet connection, which is the main advantage of using an ad hoc network. As a result, it becomes comparatively more affordable to run a mobile ad hoc network instead of a traditional network.
- It requires no installation of expensive infrastructure.
- The distribution of info and data is quick around the sender.
- There’s no single point of failure.
- You can rely on MANET for fault tolerance because it supports connection failures. The transmission and routing protocols function to manage such situations.
- The mobile nodes are free to self-organize dynamically in a temporary network topology.
- MANET is scalable and multi-hop.
Limitations of MANET
- All the entities of the network may be mobile. Thus, the topology needs to be very dynamic.
- MANET has battery constraints.
- The network functions need to have a higher adaptability degree.
- Central entities aren’t present. Thus, one needs to manage the MANET operations in a well-distributed manner.
- One needs high security in MANET, especially in military and police applications.
- A good amount of estimation and planning of future traffic growth goes into deploying MANET. It is because the required actions are different from that of the wired network.
