Security in Mobile ADHOC Networks: Survey

Mobile Adhoc Networks (MANETs) are dynamic, flexible, and mobile. While they enjoy several advanatages over traditional wireless networks due to these characteristics, their lack of infrastructure leaves them susceptible to a plethora of security threats. To better understand these threats, the traits of MANETs are elucidated and their vulnerable features are brought to light. Subsequently, the paper classifies and differentiates security attacks into various categories on several bases. Here, Data Traffic attacks, which directly affect the information being transmitted over the network, and Control Traffic attacks, which affect the flow of traffic in a network, are the primary focus. Examples of each of these attacks are explained with their functioning. Research work regarding the same have been studied and most effective countermeasures are mentioned. This paper aims to concisely summarize existing excellent research to defog uncertainties regarding the practical implementation of MANETs.
