摘要：As the trend to using portable and mobile devices with time, MANET has become the important field due to its adaptability in various applications. There is a huge requirement for such kind of networks, which easily allow users to make or establish connection for communication in between. MANET earned its popularity by its various applications, quick and easy deployment in the network between the movable nodes. There is no need of infrastructural setup to create a mobile ad hoc network setup. In MANET, Mobile nodes will communicate through a wireless medium which makes this network highly vulnerable to much kind of harmful attacks present around. The most harmful attack among the list various attacks is jellyfish attack. In this research paper, we tried an approach which can able to detect and prevent jellyfish attack with increasing number of nodes..
