Mobile Ad Hoc Network (MANET) is an infrastructure independent network with wireless mobile nodes. These networks have several advantages compared to traditional wireless networks includes ease of deployment, speed of deployment and decreased dependency on a fixed infrastructure. MANET is a kind of Ad Hoc networks with special characteristics like open network boundary, dynamic topology, distributed network, fast and quick implementation and hop-by-hop communications. These characteristics of MANET made it popular, especially in military and disaster management applications. As communication media is wireless, each node will receive packets in its wireless range, either it has been packets destination or not. Due to these characteristics, each node can easily gain access to other nodes packets or inject fault packets to the network. There have been many studies done in this area to improve the quality and efficiency of the routing protocols and security measures in MANETs. Therefore, securing MANET against malicious behaviors and nodes, became one of the most important challenge in MANET. The main contribution of this paper is that to give an overview of MANET and the routing protocols, major challenges along with the gaps in the literature. Based upon the characteristics we defined 3 important security issues. Furthermore we presented various attacks occurred in MANET along with defeating approaches and the objective measures that are used for the qualitative analysis.
