Due to a lack of infrastructure support in an environment of scalable mobile ad hoc networks (MANETs), secure data dissemination is complex. Most prior routing methods for MANETs have either ignored security or addressed a particular security aspect without improving routing performance. By studying the packet forwarding characteristics of surrounding nodes, due to the lack for various type of attacks in MANET like Blackhole, wormhole, sinkhole and rushing attacks. In this survey, we collected 36 papers to analyze the secure routing in MANETs.The causes of high mobility in terms of high traffic and malicious nodes for attacking area. MANETs require detecting misbehaving links and narcissistic nodes to prevent packet-dropping attacks. The quality of service (QoS), routing efficiency, dependability, delay per packet, packet delivery ratio, and control overheads are all examined. Here, we outline the most cutting-edge QoS-based, fault-tolerant, scalable, and reliable hybrid routing algorithms and techniques.
