An active XML (AXML) document contains tags representing calls to Web services. Therefore, retrieving its contents consists in materializing its data elements by invoking the embe...
Opportunistic networking is emerging as a technique to exploit chance encounters among mobile nodes, and is distinct from previously studied behaviors found in sensor and ad hoc n...
In an effort to improve performance of congested gateways, a new Active Queue Management (AQM) algorithm, Adaptive Virtual Queue Random Early Detection (AVQRED), was developed by ...
