Enhanced security of MANETs against black hole attacks using AS technique

Abstract

A mobile ad hoc network (MANET) is an autonomous structureless arrangement of mobile nodes to figure a momentary network. Communication between any two nodes is possible directly if the two nodes belong to the same sensing range; otherwise communication can be achieved by means of the nodes which are present between source and destination. As the network nodes are mobile, any node can enter or leave the network at any particular time interval. Thus, whichever node is present in between the source and destination can perform as a router or the host node in the arranged network. Therefore this poses security challenges to MANETs. This paper presents a solution to black hole attacks. The presented method is easy to use and efficient in detecting black hole attacks. The presented approach is validated by the use of network simulator 2 (NS2).
