A Survey on Some Currently Existing Intrusion Detection Systems for Mobile Ad Hoc Networks

Mobile Ad-Hoc Network (MANET) is one of the most promising technologies that have applications in military, environmental, space exploration and forestry industry areas. This type of network has attractive features such as its low transmission power to conserve energy, increase throughput, and reduce delay. However, it suffers from many constraints, including limited resources, and the use of insecure wireless communication channels. Due to the lack of defense, the security of these networks is a worthy concern, particularly for the applications where confidentiality has prime importance. Thus, any kind of intrusions should be detected before attackers can harm the network in order to operate MANET in a secure way. In this article, we present a survey of the state-of-theart in Intrusion Detection Systems (IDSs) that are proposed for MANETs. This is followed by a comparison of each scheme along with their advantages and disadvantages. This survey is concluded by highlighting open research issues in the field.
