Abstract: A Mobile Ad hoc Network (MANET) is a network consisting of a set of mobile hosts capable of communicating with each other without the assistance of base stations. This type of network having tiny light weighted nodes, with no clock synchronization mechanisms. In a MANET there are no dedicated routers and all network nodes must contribute to routing. Classification of routing protocols for MANET is based on how routing information is acquired and maintained by mobile nodes and/or on roles of network nodes in a routing. The wireless and distributed nature of MANETs poses a great challenge to system energy and the security. Mobile Ad hoc Networks (MANET) is a set of wireless mobile nodes dynamically form spontaneous network which works without centralized administration. Due to this characteristic, there are some challenges that protocol designers and network developers are faced with. These challenges include routing, service and frequently topology changes. Generally, in this type of network the exhaustion of energy will be more and as well, the security is missing due to its infrastructure less nature. There are also limited battery power and low bandwidth available in each node. Security attacks against MANET routing can be passive and or active. An overview of active attacks based on modification, impersonation/spoofing, fabrication, wormhole, and selfish behaviour is presented. A comparison of existing secure routing protocols form the main contribution in this paper, while some future research challenges in secure MANET routing are discussed.
