"MANETs are usually characterized by limited resources such as bandwidth, battery power, and storage space and node mobility. The underlying assumption is that the intermediate nodes cooperate in forwarding packets. Due to lack of infrastructure, the network can be easily affected by several attacks. The security challenges in MANET have become a primary concern to provide secure communication. The Attacks on MANET disrupts network performance and reliability. Now-a-days, DoS attacks are usually launched in a distributed way: known as DDoS attacks i.e. the attacks where traffic originates from many attacking sources and the aggregated traffic volume is so big that it can easily deplete the victim's key computing resources, such as bandwidth and CPU time."
