ABSTRACT
Intrusions in wireless ad-hoc networks are of a fleeting nature. Securing wired local area networks (LANs) is an easier task, as power no longer remains a constrained resource. This allows any number of highly efficient intrusion prevention techniques to be implemented for securing the network. The very insecure nature of the wireless medium makes it open to a vast array of ever-increasing threats. Since wireless networks tend to be ad-hoc, the very nature of the attacks or threats also tends to be the same. Again, one of the most severe resource constraints of such wireless ad-hoc networks is energy or battery life of the nodes forming the network. This major drawback prevents the network operators from deploying computation-intensive intrusion prevention security protocols, as they would take a toll on the battery life of these wireless nodes. Intrusion prevention systems give way to less computation-intensive and energy-efficient security systems-intrusion detection systems.
