Local monitoring is an effective mechanism for the security of wireless sensor networks (WSNs). Existing schemes assume the existence of sufficient number of active nodes to carry...
Abstract--Two well-known problems that can cause performance degradations in IEEE 802.11 wireless networks are the exposednode (EN) and hidden-node (HN) problems. Although there ha...
Constructing sensor barriers to detect intruders crossing a randomly-deployed sensor network is an important problem. Early results have shown how to construct sensor barriers to ...

Abstract Algorithms for scheduling TDMA transmissions in multi-hop networks usually determine the smallest length conflict-free assignment of slots in which each link or node is a...
—Wireless Sensor Networks provide opportunities even outside their usual application domain of environmental monitoring. In this paper we present a case study on the use of Wirel...
