Detection Approach for Denial of Service Attack in Dynamic Wireless Networks
Deepesh Namdev, Monika Mehra · 2014
Mobile ad hoc networks are dynamic mobile networks that can be formed in the absence of any pre-existing communication infrastructure. In addition to node mobility, a MANET is characterized by limited resources such as bandwidth, battery power, and storage space. The underlying assumption in MANETs is that the intermediate nodes cooperate in forwarding packets. However, this assumption does not hold in commercial and emerging civilian applications. MANET is quickly spreading for the property of its capability in forming rapidly changing topologies network without the aid of any established infrastructure or centralized administration. The security challenges in MANET have become a primary concern to provide secure communication. The Attacks on MANET disrupts network performance and reliability. The DOS (denial-of- service), Distributed denial-of-service (DDoS) attacks are a rapidly growing problem. The multitude and variety of both the attacks and the defence approaches is overwhelming. These attacks lead toward the degradation or prevention of legitimate use of network resources. In this paper kind of attacks are presented which are attacked on ad-hoc network. The motive of the study is aware about different service availability attacks and its effects on network operation.
