Attacks and Security Issues of Mobile Ad Hoc Networks

Abstract

Mobile Ad Hoc Network has acknowledged a large amount of interest among users by forming a temporary network. MANET does not have any fixed infrastructure. Due to the dynamic changing topology+, such type of network suffers various challenging issues like limited wireless range of nodes, dynamic topology, bandwidth consumption, transmission errors etc. MANET has no clear line of defense; Security is a priority for safe communication in any environment. The mischievous nodes can attack from both the sides of the network. In the existence of false nodes, the major concern of such networks is to layout the effective security solution, which protects MANET from distinct routing attacks. All the nodes in the network forward the data towards the destination; therefore, MANET is more prone to attacks by malicious nodes, such as black hole, wormhole, Denial of Service (DoS), eavesdropping, spoofing, etc. This paper, firstly deals with the challenges faced by the MANET. Secondly, it focuses on significant security attacks and safety issues of mobile ad hoc networks. And finally, it mentions the recent research work done on security solutions for wireless network.
