MANETs: Challenges and Future Research Scope

MANET (Mobile Ad hoc Network) is an ad hoc network that may be constructed on demand. Due to its dynamic nature, it allows nodes in the network to communicate with each other without the use of any infrastructure. When compared to conventional wireless networks, MANET's on-demand setup makes it more popular. Conventional wireless networks require a central authority for overall system operations, while MANET is an infrastructure-less and self-organized network that is generally a wise choice when it comes to certain application areas like military operations, communication in natural disasters, man-made emergencies, rescue procedures, and vehicular ad hoc network (VANET) for sharing information among vehicles as well as providing traffic conditions and warnings. This new network, however, faces several challenges and difficulties, including compromised security, routing issues, cooperation, multicasting, power efficiency, IP addressing, QoS etc., that must be properly taken care of before it can be deployed in real-time. The current paper provides a full analysis of MANET, including its problems, concerns, and possible research topics, which will be very useful for academics who want to begin their work on this subject.
