With the advancement of wireless communication technology, Mobile Ad Hoc Networks (MANET) is a prominent self-organized network technology without any network infrastructure. MANET has unique features such as adaptive and self-organizing nature, dynamic topology, multi-hop routing, and limited bandwidth, and it provides enormous services to mobile users. With its immense growth in recent days, MANET has played a significant role in many fields such as healthcare, military, emergency services, education, and many others areas. Although, because of MANET-s distinctive characteristics, it encountered several challenges, including security and reliability, multicast routing, Quality of Service, and data confidentially. Moreover, several routing attacks also occur in MANET, including Single Black Hole Attack, Traffic Analyse Attack, Denial of service, Sybil Attack, and many others. This section provides leading research books in MANET as LAP Lambert Academic Publishing, CRC Press, Taylor & Francis Group, Springer Berlin Heidelberg, and among others.
