— Group Communication services have become more and more important in mobile ad hoc networks (MANETs). The use of multicast transmission techniques in MANETs has been shown to ha...
In this paper, we present a new "spatiotemporal multicast", called a "mobicast", protocol for supporting applications which require spatiotemporal coordination...
Key management in wireless sensor networks does not only face typical, but also several new challenges. The scale, resource limitations, and new threats such as node capture and c...

Abstract--Wireless sensor networks (WSNs) deployed in hostile environments are vulnerable to clone attacks. In such attack, an adversary compromises a few nodes, replicates them, a...
Wireless sensor networks (WSNs) are typically characterized by a limited energy supply at sensor nodes. Hence, energy efficiency is an important issue in the system design and op...
