Deciphering the Full Form of MANET

The acronym MANET stands for Mobile Ad Hoc Network. It's a term that's often thrown around in tech circles, but what does it really mean?

MANET is a type of wireless network that doesn't rely on a fixed infrastructure like traditional wired networks do. Instead, it's decentralized and can operate without the need for routers or access points. This makes it incredibly flexible and adaptable. MANETs can be connected using various mediums, such as Wi-Fi, satellite, or cellular transmission, and they function as a self-organizing network of mobile routers that are connected via wireless links.

In a MANET, each device operates autonomously. They are free to move around, and as they do so, they automatically organize themselves. This means that the network's structure can change dynamically and unpredictably, which can sometimes lead to broken communication links as devices move around.

A Brief Look at the History of MANET

• MANETs have evolved over time, and can be grouped into three generations.
• The first generation was characterized by the development of packet radio networks (PRNETs), which were sponsored by DARPA in the early 1970s.
• The second generation emerged in the 1980s, with the introduction of Survivable Adaptive Radio Networks (SURANs), which greatly improved the scalability and resilience of these networks.
• This period also saw the development of the Near Term Digital Radio (NTDR) and Global Mobile Information System (GloMo).
• The third generation came about in the 1990s, thanks to the arrival of open-source software, notebook computers, and RF and infrared-based tools. This generation of MANETs was used more commercially.

The Advantages of Using MANETs

• High-performance network capabilities.
• Lower operational costs due to the lack of need for routers or access points.
• No need for expensive infrastructure installation.
• Fast and efficient information distribution.
• No single point of failure.
• Fault tolerance, with transmission and routing protocols designed to handle connection failures.
• Dynamic self-organization of mobile nodes in a temporary network topology.
• Scalability and multi-hop capabilities.

The Drawbacks of MANETs

• Highly dynamic topology due to the mobility of network entities.
• Battery life constraints.
• Need for higher degrees of network function adaptability.
• Lack of central entities, requiring well-distributed network management.
• High security requirements, especially in military and law enforcement applications.
• Planning and estimation requirements for future traffic growth, due to differences from wired networks.
