Mobile ad hoc are gaining popularity because of availability of low cost mobile devices and its ability to provide instant wireless networking capabilities where implementation of wired network is not possible or costly. MANETs are vulnerable to various types of attack because of its features like continuous changing topology, resource constraints and(More)
With emergence of a wide range of wireless devices, protecting mobile ad hoc networks became an increasingly important and also a more difficult task. Intrusion detection system (IDS) can be deployed as a second line of defense in a mobile ad hoc network (MANET). But it may be impossible to make every wireless node the monitoring nodes due to the resource(More)
Mobile ad-hoc network (MANET) is a self-deliberate data network, where all nodes behave like host or router. MANET is a collection of number of mobile nodes or devices that randomly generate a temporary network. Security is the fundamental requirement in MANET due to its behavior of changing topology, open medium and lack of centralized authentication. This(More)
In mobile ad hoc networks (MANET), various types of denial of service attacks (DoS) are possible because of the inherent limitations of its routing protocols. The attack of initiating/forwarding fake route requests (RREQs) can lead to hogging of network resources and hence denial of service to genuine nodes. This type of attack is hard to detect since(More)
