Inter-Domain QoS routing (route selection from multiple available routes traversing multiple domains) simply on the basis of hop count does neither ensure optimal resource utilization nor SLA fulfillment. Although some schemes (BGP-4) provide policy based routing, they are not suitable in many cases, for example, in case of resource reservation. In this paper, we argue that these schemes alone ...

This paper presents a closed-form spectral evaluation of the family of digital pulse interval modulation (DPIM) schemes, where the information is contained in the relative distance between successive pulses. The framework for spectral evaluation is that of Stationary Symbol Sequences derived from Variable-Length Word Sequences, which considers the issue of stationarization, a preliminary task t...

The numbers of greenbugs, Schizaphis graminum (Rondani), and bird cherry-oat aphids, Rhopalosiphum padi L., per wheat tiller (stem) were estimated in 189 production winter wheat (Triticum aestivum L.) fields located throughout Oklahoma. Taylor's power law regressions were calculated from these data and used to construct fixed precision sequential sampling schemes for each species. An evaluation...

Classical collaborative filtering algorithms that generate recommendations on the basis of item ratings use standard aggregation schemes that are devised a priori, without a process of empirical assessment. Nonetheless, common empirical evaluation procedures can be used to obtain evidence of the appropriateness of changing the behavior of the aggregation schemes. This paper reports the empirica...

Database caching uses full-fledged DBMSs as caches to adaptively maintain sets of records from a remote DB and to evaluate queries on them, whereas Web caching keeps single Web objects ready somewhere in caches in the user-to-server path. Using DB caching, we are able to perform declarative and setoriented query processing nearby the application, although data storage and consistency maintenanc...

We present a technique for deriving incremental implementations for a subclass of algebraic speciications, namely, conditional well-presented primitive recursive schemes. We use concepts of the translation of well-presented primitive recursive schemes to strongly non-circular attribute grammars, storing results of function applications and their parameters as attributes in an abstract syntax tr...

The reliable execution of a mobile agent is a very important design issue to build a mobile agent system and many fault-tolerant schemes have been proposed. Hence, in this paper, we present evaluation of the performance of the fault-tolerant schemes for the mobile agent environment. Our evaluation focuses on the checkpointing schemes and deals with the cooperating agents. We derive the FANTOMAS...

Garbled circuits, a classical idea rooted in the work of Andrew Yao, have long been understood as a cryptographic technique, not a cryptographic goal. Here we cull out a primitive corresponding to this technique. We call it a garbling scheme . We provide a provable-security treatment for garbling schemes, endowing them with a versatile syntax and multiple security definitions. The most basic of...

Hence, in this article, we present an evaluation of the per formance of the fault-tolerant schemes for the mobile agent environment. Our evaluation focuses on the checkpointing schemes and deals with the cooperating agents. We derive the Fa...
