Abstract
Distributed Denial of Service (DDoS) attacks in the networks needs to be prevented or handled if it occurs, as early as possible and before reaching the victim. Dealing with DDoS attacks is difficult due to their properties such as dynamic attack rates, various kinds of targets, big scale of botnet, etc. Distributed Denial of Service (DDoS) attack is hard to deal with because it is difficult to distinguish legitimate traffic from malicious traffic, especially when the traffic is coming at a different rate from distributed sources. DDoS attack becomes more difficult to handle if it occurs in wireless network because of the properties of ad hoc network such as dynamic topologies, low battery life, multicast routing, frequency of updates or network overhead, scalability, mobile agent based routing, and power aware routing, etc. Therefore, it is better to prevent the distributed denial of service attack rather than allowing it to occur and then taking the necessary steps to handle it. This paper discusses various the attack mechanisms and problems due to DDoS attack, also how MANET can be affected by these attacks. In addition to this, a novel solution is proposed to handle DDoS attacks in mobile ad hoc networks (MANETs).

In view of the increasing demand for wireless information and data services, providing faster and reliable mobile access is becoming an important concern
This paper discusses various the attack mechanisms and problems due to Distributed Denial of Service (DDoS) attack, how mobile ad hoc networks (MANETs) can be affected by these attacks
The main aim of flooding attack is to paralyze the entire network by inserting overwhelming attack traffic (e.g. route request (RREQ) broadcasting) into the MANET
Summary
In view of the increasing demand for wireless information and data services, providing faster and reliable mobile access is becoming an important concern. Its routing protocol has to be able to manage with the new difficulties that an ad hoc network creates such as nodes mobility, limited power supply, quality of service, bandwidth issues, changing topology and security issues. These challenges set new requirements on MANET routing protocols and make them more vulnerable to attacks [2]. A DDoS attack is a distributed, large-scale attempt by malicious users to flood the victim network with an enormous number of packets This exhausts the victim network of resources such as bandwidth, computing power, etc. Rest of the paper is organized as follows: Section 2 describes related work, Section 3 presents over of DDoS attacks, Section 4 describes MANET overview, Section 5 describes proposed prevention scheme, and Section 6 concludes the paper and discusses some future work
