Black-hole Attack in MANET
Networking , Technology & Science / August 17, 2017

Mobile Ad-hoc Network(MANET) Attack Wireless networks can be basically either infrastructure based networks or infrastructure less networks. The infrastructure based networks uses fixed base stations, which are responsible for coordinating communication between the mobile hosts (nodes). The ad hoc networks falls under the class of infrastructure less networks, where the mobile nodes communicate with each other without any fixed infrastructure between them. An ad hoc network is a collection of nodes that do not rely on a predefined infrastructure to keep the network connected. So the functioning of Ad-hoc networks is dependent on the trust and co-operation between nodes. Nodes help each other in conveying information about the topology of the network and share the responsibility of managing the network. Hence in addition to acting as hosts, each mobile node does the function of routing and relaying messages for other mobile nodes. Black-hole Attack Security in a MANET is an essential component for basic network functions like packet forwarding and routing.  Before we survey the solutions that can help secure the mobile ad hoc network, we think it necessary to find out how we can judge if a mobile ad hoc network is secure or not, or in other words,…
