In relation to its growth in size and user population, the Internet faces new challenges that have triggered the proposals of value-added network services, e.g., IP multicast, IP ...
In wireless sensor networks (WSNs), when a stimulus or event is detected within a particular region, data reports from the neighboring sensor nodes (sources) are sent to the sink ...
To defend against multi-step intrusions in high-speed networks, efficient algorithms are needed to correlate isolated alerts into attack scenarios. Existing correlation methods us...
