Black Hole Attack Countermeasures in Mobile Adhoc Networks
A mobile adhoc network (MANET) is an infrastructure-less type network, which consists of number of mobile nodes with wireless network interfaces. In MANET every node can functions as transmitter, router and data sink. MANET has dynamic topology which allows nodes to join and leave the network at any point of time. MANET is more vulnerable due to its characteristics such as dynamic topology, dis...
متن کاملTechnique for Detection of Cooperative Black Hole Attack in Mobile Ad-hoc Networks-Survey
Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure and pre-determined organization of available links. Security is a major challenge for these networks owing to their features of open medium, dynamically changing topologies. The black hole attack is a well known security threat in MANET. However, it spuriousl...
متن کاملIntrusion Detection System in Mobile Adhoc NETworks :
In recent years, the use of mobile ad hoc networks (MANETs) has been widespread in many applications, including some mission critical applications, and as such security has become one of the major concerns in MANETs. Additionally, the limited processing power and battery life of the devices used in a MANET also prevent the adoption of heavy-duty cryptographic techniques. While traditional misus...
متن کاملProactive Approach for Cooperative Caching in Mobile Adhoc Networks
In Mobile Adhoc Networks (MANETs), due to frequent network partition, data availability is lower than that in traditional wired networks. Cooperative caching provides an attractive solution for this problem. In this paper we propose a new proactive approach for cooperative caching in MANETs, in which we will cache the data of leaving node. Here each mobile node will broadcast a “LEAVE” message ...
متن کاملA New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
