Abstract-- Node compromise is a serious threat to wireless sensor networks deployed in unattended and hostile environments. To mitigate the impact of compromised nodes, we propose ...
Addition of new nodes to a Sensor Network is a fundamental requirement for their continuity operation over time. We analyze the weakening of security due to node capture when addi...
Event boundary detection is in and of itself a useful application in wireless sensor networks (WSNs). Typically, it includes the detection of a large-scale spatial phenomenon such ...
In wireless sensor networks, energy efficiency is crucial to achieve satisfactory network lifetime. In order to reduce the energy consumption of a node significantly, its radio ne...
Wireless sensor networks pose numerous fundamental coordination problems. For instance, in a number of application domains including homeland security, environmental monitoring an...
