Abstract
Security in mobile ad hoc networks is difficult to achieve, notably
because of the vulnerability of wireless links, the limited physical protection
of nodes, the dynamically changing topology, the absence of a certification
authority, and the lack of a centralized monitoring or management point.
Earlier studies on mobile ad hoc networks (MANETs) aimed at proposing
protocols for some fundamental problems, such as routing, and tried to
cope with the challenges imposed by the new environment. These protocols,
however, fully trust all nodes and do not consider the security aspect.
They are consequently vulnerable to attacks and misbehavior.
More recent studies focused on security problems in MANETs, and proposed
mechanisms to secure protocols and applications. This article surveys
these studies. It presents and discusses several security problems along with
the currently proposed solutions (as of July 2005) at different network layers
of MANETs. Security issues involved in this article include routing and
data forwarding, medium access, key management and intrusion detection
systems (IDSs). This survey also includes an overview of security in a particular
type of MANET, namely, wireless sensor networks (WSNs).
