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 …

The highly anticipated 5G network is projected to be introduced in 2020. 5G stakeholders
are unanimous that densification of mobile networks is the way forward. The densification …

We consider routing security in wireless sensor networks. Many sensor network routing
protocols have been proposed, but none of them have been designed with security as a …

Key establishment in sensor networks is a challenging problem because asymmetric key
cryptosystems are unsuitable for use in resource constrained sensor nodes, and also …

As mobile ad hoc network applications are deployed, security emerges as a central
requirement. In this paper, we introduce the wormhole attack, a severe attack in ad hoc …

Sensor networks hold the promise of facilitating large-scale, real-time data processing in
complex environments, helping to protect and monitor military, environmental, safety-critical …

Most recent ad hoc network research has focused on providing routing services without
considering security. We detail security threats against ad hoc routing protocols, specifically …

Secure operation of the routing protocol is one of the major challenges to be met for the
proliferation of the mobile ad hoc networking (MANET) paradigm. Nevertheless, security …

Security has become a primary concern in order to provide protected communication
between mobile nodes in a hostile environment. Unlike the wireline networks, the unique …

To achieve security in wireless sensor networks, it is important to he able to encrypt
messages sent among sensor nodes. Keys for encryption purposes must he agreed upon by …
