Traffic engineering issues require major adjustments, as the DiffServ architecture is gaining ground. In addition, the measurementbased strategy shows the advantages of flexibility and easy adaptation. This article reviews measurement-based packet/cell dropping schemes. Based on the definition and investigation of a “packet shortage” phenomenon, a new dropping scheme for proportionally differen...

In this paper‎, ‎an efficient dropping criterion has been used to compute the IUL factorization obtained from Backward Factored APproximate INVerse (BFAPINV) and ILU factorization obtained from Forward Factored APproximate INVerse (FFAPINV) algorithms‎. ‎We use different drop tolerance parameters to compute the preconditioners‎. ‎To study the effect of such a dropping on the quality of the ILU ...

We explore the advantages of intelligently dropping a small fraction of packets that arrive for transmission over a time varying wireless downlink. Without packet dropping, the optimal energy-delay tradeoff conforms to a square root tradeoff law, as shown by Berry and Gallager (2002). We show that intelligently dropping any non-zero fraction of the input rate dramatically changes this relation ...

In this paper, the notion of declarative goals as used in agent programming is central. Declarative goals describe desirable states and are updated during the execution of an agent. These goal dynamics are analyzed by distinguishing and formalizing various notions of goal dropping and goal adoption. Furthermore, possible motivations for an agent to drop or adopt goals are identified. Based on t...
