Abstract: The wireless Network is an emerging technology in the field of communication. The communication may take place between computers, networking nodes etc. A mobile ad hoc network (MANET) is a continuously self-configuring, infrastructureless network of mobiles connected wirelessly. The best examples are routers in wired networks or access points in managed wireless networks. Mobile ad-hoc wireless networks (MANETs) exhibit high variability in network topology and communication quality. The network topology is dynamically changing and has no centralized administration. The nodes in the network are connected to transfer data, but the wireless channel suffers from attacks. Security plays an important role in mobile ad hoc network and is an essential requirement in MANETS. The wireless networks need more securitythan wired networks because it has limited resources. There are security issues and challenges. Some challenges here are dynamically changing network structure, limitations of mobile nodes, infrastructure less etc. Thispaper focuses on the routing attacks, as well as solutions against such attacks in existing MANET protocols.
