The Adaptive Random Testing (ART) was devised to improve the performance of pure random tests, which is one of black-box testing strategies. The ART-based algorithms were developed mainly for unit or single module tests. When a given unit-under-test (UUT) is integrated with an already proven front-end software module which takes inputs and supplies the(More)
We present a recipe based service composition scheme in smart spaces. We discuss real time problems of highly synchronized and user customizable processes with the help of an example. On-the-fly Quality of Service (QoS) shows up as a major issue in such environment. Furthermore the QoS of a dynamically composed service depends upon the aggregate QoS of its(More)
Routing queries from a base station to a particular WSN node is preferable when it is done in a content oriented manner. Previously proposed query routing schemes are either not content based or lack to take advantage of a hierarchical organization of the network when they are content based. In this paper, we propose a hierarchical, service oriented routing(More)
