2006-04-12BuchMatching Nondeterministic Services with Operating Guidelines Interorganizational cooperation is more and more organized by the paradigm of services. The service-oriented architecture (SOA) provides a general framework for service interaction. It describes three roles, service provider, ...

2009-01-01BuchMax-Type Rank Tests, U-Tests, and Adaptive Tests for the Two-Sample Location Problem - An Asymptotic Power Study For the two-sample location problem we first consider two types of tests, linear rank tests with various scores, but also some tests based on U-statistics. For both types we construct adaptive tests as well as max-type ...

2006-11-21BuchModeling Event-driven Time Series with Generalized Hidden Semi-Markov Models This report introduces a new model for event-driven temporal sequence processing: Generalized Hidden Semi-Markov Models (GHSMMs). GHSMMs are an extension of hidden Markov models to continuous time that builds on turning ...

2006-01-01BuchMulti-Channel Opportunistic Routing in Multi-Hop Wireless Networks We propose and investigate Multi-Channel Extremely Opportunistic Routing (MCExOR) which is a protocol that extends Extremely Opportunistic Routing by utilizing multiple RF channels in multi-hop wireless networks. Large ...

2008-01-01BuchNPART - Node Placement Algorithm for Realistic Topologies in Wireless Multihop Network Simulation Despite a considerable number of topology generation algorithms for simulation of wireless multihop networks it is difficult to find one with output similar to real networks [13]. In this paper, we propose NPART { a Node ...

2005-04-19BuchOperating Guidelines - an Alternative to Public View
-
2006-01-01BuchOperating Guidelines for Finite-State Services We introduce the concept of an operating guideline for an arbitrary finite-state service P, extending the work of [1, 2] which was restricted to acyclic services. An operating guideline gives complete information about how ...

2005-06-30BuchParallel event detection in active database systems This paper proposes a strategy for parallel composite event detection in Active database systems (DBS). Up to now, the detection is sequential and totally synchronized, and thus preserves the timely order of events during ...
-
1996-05-22BuchPetri Net Based Verification of Distributed Algorithms A technique to describe and to verify distributed algorithms is suggested. This technique (based on Petri nets) reduces the modelling- and analysis effort to a reasonable expenditure. The paper outlines the technique along ...

-
2007-09-21BuchPrototyping and Simulating Domain-Specific Languages for Wireless Sensor Networks The development of software for wireless sensor networks is involved and complex. This does not only impose much work on programmers but also prevents domain experts from directly contributing parts of the software. ...
