When people want to talk to one another where they are using their mobile devices, free of the Wi-Fi or cell phone networks, they turn to what are known as "mobile ad hoc networks" (often shortened to "MANETs. A MANET is an ad-hoc network consisting of mobile devices like smartphones, tablets, or other mobile devices that can directly communicate with one another. That means there’s no central server they need to facilitate, or even internet connection, to send messages back and forth. Instead, such devices can communicate with one another using short-range technologies like Bluetooth, Wi-Fi, or established protocols such as MANET protocols that assist them to collaborate effectively.
Flexible It is one of the best feature of MANETs. They can be deployed in minutes and places where there is no traditional internet service or cell phone reception. This is super useful in scenarios like disaster-affected zones where people need to communicate with each other but conventional communication systems may not be functioning. It can also assist military teams or groups at outdoor events in stylized communication, without requiring outside help or other resources. So, in a number of ways, MANETs can be lifesaver in troublesome situations.
But we associated some issues, which limits using MANET. And, their reliability is a significant issue. Because there’s not a central control point, each device in the network has to collaborate and share information with one another to ensure messages are transmitted through. If even a single device fails to function or disconnects from the network, the whole communication network may collapse. Finally, because these devices communicate over wireless signals, they may be subject to interference from other devices. It traces both broadcast and reception sensitivity, so if too many are in a space it could be difficult for them to communicate with each other.
Security is one of the major challenges of MANETs. As there is no central authority to supervise and administer the network, preventing unauthorized access to the network is a cumbersome process. This includes stops to keep individuals from eavesdropping, which implies tuning in on discussions without consent, or even attempting to con others with counterfeit data. In military or emergency contexts this consideration is paramount, since sensitive or private information may also be shared.
Various strategies can be implemented to secure MANETs and mitigate these potential security threats. This includes techniques such as encryption, authentication, and intrusion detection. Encryption is a technique that scrambles messages so that only the intended recipients can read them. So, even if a message is intercepted, it was unreadable. Authentication is another key technique that verifies if the entity who is sending the message is the same entity who purports to be sending the message. Finally, intrusion detection system used to detection and prevention of unauthorized activity to be alarmed on time and stop possible harm to the network. Well these all are important strategies to make communication secure.
Not only important during emergency conditions MANETs have several practical applications for day to day usage. For example, if you and your friends want to play a multiplayer game among yourselves or transfer files, but that too without using your mobile data or using a public Wi-Fi, then you can build a MANET. That enables you to link them together without requiring an Internet connection. Furthermore, MANETs are useful for forming ad hoc social networks or chat rooms for particular events like concerts, conferences or any other meeting place in which individuals wish to connect and exchange information rapidly.
Moreover, with the development of artificial intelligence (AI) and machine learning, much of it can be very helpful for MANETs. They can assist in making the networks more reliable, secure, and efficient. For instance, algorithms now modeled by AI can assist with message routing so that messages reach their destinations as quickly and clearly as possible. They can also aid in identifying and protecting against cyber attacks, maintaining the integrity and security of the network against dangerous threats.
