Mobile Ad-hoc network also abbreviated as MANET, is the most dynamic technology that works on routable networking as it utilizes movable wireless devices. In other words, it is the wireless network that works without any infrastructure. It holds a set of mobile nodes such as smartphones, laptops, iPads, and PDAs, that are connected in a self-healing and auto-configured wireless network. When MANET is connected to these nodes, they act as a router to transfer packets to other spaced nodes. MANET is also known as an Ad-hoc wireless network or wireless Ad-hoc network.
MANET can be operated in a standalone way or be a part of a larger internet. They can create a highly dynamic and autonomous topology through one or multiple transceivers between the nodes. It is alleged that MANET equips each device to maintain the information that is required to route traffic properly. It also comprises a peer-to-peer, self-healing network that typically communicates at around 30MHz to 5GHz of radio frequencies. The applications of MANET are to create systems for road safety, disaster rescue operations, weapons, sensors for the environment, robots, air/navy/land defense, and so on.
What are the Characteristics of MANET?
Autonomous Behaviour: Each node works as a router and host that shows its autonomous behavior.
Dynamic Technologies: MANET works on the network topology that’s usually multi-hop and changes rapidly & randomly. It can create bidirectional or unidirectional links.
Variable Capacity Bandwidth-constrained Links:
Wireless links typically have lower efficiency, reliability, capacity, and stability as compared to the wired network.
Limited Security: MANET is a wireless network thus it is more vulnerable to security threats. Due to the distributed operation for routing, security, and host configuration, a centralized firewall is absent.
Energy Constrained Operation:
As some nodes work on batteries or other means of energy, they are characterized by less power, memory as well as lightweight features.
Minimal Human Intervention:
MANET needs less human intervention for network configuration, thus they are dynamically autonomous.

What are the Advantages of MANET?
Scalability: MANET is capable of scaling to accommodate multiple nodes while making them perfect for large-scale deployments. Also, they can handle dynamic changes that happen in the network topology, such as removal or addition of nodes.
Flexibility: MANET offers many advantages due to higher flexibility. They can be deployed in different environments and can be used in different scenarios and applications. Thus, they are considered ideal for military operations and emergencies, where the network infrastructure is not present.
Rapid Deployment:
MANET ensures rapid deployment in areas where pre-existing network infrastructure is not available such as rural areas or disaster zones.
Cost Savvy: As centralized infrastructure is not required, MANET is considered an effective option as compared to traditional wireless or wired networks. Also, they can be used to increase the range of existing networks without any additional infrastructure.
Expected Improvement in MANET:
Power Management: Researchers are working on developing top-notch power management techniques for mobile Ad-hoc networks to improve the lifetime of MANET nodes.
Multimedia Support: Experts are working to provide multimedia support to MANET. They are developing routing protocols that can efficiently manage the traffic.
Security: Researchers are working on building highly efficient and robust security mechanisms to ensure encryption, authentication as well as authorization features.
QoS (Quality of Service): Researchers are also working on improving the QoS of mobile ad-hoc networks through routing protocols that offer improved latency, bandwidth, and throughput.
Standardization: Researchers are working on building standard interfaces and protocols to ensure the interoperability of MANET devices.
Summarizing this, MANET (Mobile Ad-hoc Network) is a wireless network that is built up of a set of mobile nodes without any fixed infrastructure. As mentioned above, MANET offers a lot of advantages but there are several drawbacks too that need to be resolved. Researchers are trying to make the features and capabilities of MANET better. It is anticipated that the evolving technologies will make MANET a more effective and dependable wireless network.
