Security Routing in MANETs - A Comparative Study

Mobile-IP ad-hoc networks (MANETs) have gained popularity in the past few years with the creation of variety of ad hoc protocols that specifically offer quality of service (QoS) for various multimedia traffic between mobile nodes (MNs) and base stations (BSs). The lack of proper end-to-end 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 variety of forms. The attention of this paper is to overview types of attacks in MANETs and the introduction of two entities; ad-hoc key distribution center (AKDC) and decentralize key generation and distribution (DKGD). Through simulations, the performance of these functional entities is compared to current schemes
