Ad hoc networking enables devices to communicate directly with each other without the need for a Wi-Fi router or a central device. It is an ideal temporary network setup where internet access is not available. Laptops, smartphones, tablets, and even drones can be connected wirelessly via Bluetooth. This makes it easy to share files, messages, and photos between nearby users.
However, there are some disadvantages in working with ad hoc networks. The most serious drawback is that they are so much less secure than traditional networks. Since the network has no central access point, a hacker or unauthorized user can sometimes enter the network a bit more easily and even attempt to steal information. Besides, with a limited spatial range; it is deployed only for the devices in the short range. If you get too far away, the connection may be weak or not work at all. In a crisis, rapid communication is of the utmost importance. During crises, people can use ad hoc networks for information sharing and to communicate with one another. (Again, ignoring P2P networks, connects via traditional means) For instance, during a natural disaster like an earthquake or hurricane, the normal communication networks may collapse or be completely unavailable. In such harsh conditions, there is a need for ad hoc networks that will enable rescuers, volunteers, and emergency responders to communicate faster and share critical information with one another.
Ad hoc networks can be highly convenient and make sense in times of emergency but also present security and privacy issues. Also, without a central access point it also makes it easier for hackers to attempt to get onto the network. This could allow personal information, including messages and photos, to be intercepted and stolen. Data breaches, market manipulation, hacks, and fraud — all make the list. Protect against these by using strong passwords and encryption.
Encryption is one of the ways that helps to keep secret information secure by scrambling that information such that it is unreadable to those who should not be able to see it. That information can only be decrypted and read by authorized devices that have the appropriate keys. It’s not a bad idea to restrict who even joins the network, allowing only your trusted devices and users. It is also important to look out for deployment of ad hoc networks unrecognizable devices trying to connect, to confirm safety.
Another exciting development in this space is that of ad hoc wireless communication. A mesh network is a sub-type of network topology that is quite distinctive as it can span across several connecting devices per network node. EE’s better approach to mobile adhoc networking share gives a larger more stable platform. If one of those devices fails or loses connectivity, the others can still talk to each other. This greatly enhances mesh networks and strengthens their ability to withstand challenges like network failure.
