Mobile Ad Hoc Networks is an emerging trend through self configuring independent network environment consists of nodes and links. Due to this spontaneous configuring nature, it is more vulnerable to many attacks. Security is the vital concern in MANET. There are lot of attack strategies are vulnerable in the MANET. In this various attacks, the network layer attacks cause more vigorous. In network layer, the nodes are connected with the nodes in that range and the network formation and data transmission will be done through the multi hop wireless based routing scheme. The detection and mitigation of these attacks makes more complex when it deals with the n number of nodes and links. The detection and mitigation techniques are developed to isolate the attacks and not to make any impact to the legitimate nodes. This paper describes the network layer attacks and its detection and mitigation strategies with their performance. In this paper, the detection strategies are also compared with one another through the results provided from the references.
