Security measures for mobile ad-hoc networks (MANETs)

Mobile ad hoc networks (MANETs) have gained popularity in the past decade with the creation of a variety of ad hoc protocols that specifically offer quality of service (QoS) for various multimedia traffic between mobile stations (MSs) and base stations (BSs). The lack of proper end-to-end security coverage, on the other hand, is a challenging issue as the nature of such networks with no specific infrastructure is prone to relatively more attacks, in a variety of forms. The focus of this chapter is to discuss a number of attack scenarios and their remedies in MANETs including the introduction of two entities; ad hoc key distribution center (AKDC) and decentralize key generation and distribution (DKGD), which serve as key management schemes.
