Runtime testing of dynamically evolvable systems is known as a complex and challenging activity. Undesired side effects may be introduced as the interference between test cases and business functionalities of the components under test. To handle such problem, test isolation strategies are used to execute runtime tests safely. In this proposal, we discuss the need to adapt the well known test isolation mechanisms to cope with heterogeneity of the components under test. For doing this, we define a Test Isolation Policy that produces the suitable test isolation solution depending on the testability degree of each component under test. We show its usefulness by the means of a case study in the healthcare domain, called Teleservices and Remote Medical Care System (TRMCS). Some experiments are carried out to show the efficiency of our approach and the low overhead it introduces.

Bootstrapping is one of the most crucial issues in Wireless Sensor Networks (WSN) especially at the case of ring-based protocols where all the nodes should be placed into one global consistent ring. Recent approaches are unable to form directly one global ring. They form as a first step multiple rings, then add an additional step to fuse all the rings into one global consistent ring. We have proposed in a recent work a solution that avoids the formation of separated rings and forms directly one global consistent ring by orchestrating the nodes joining process and avoiding concurrent joining. In this paper, we investigate the following problem: Since our bootstrapping approach has multiple sequential steps whose durations are ensured by timers, we should estimate the maximal duration of each step in order to optimize the total time needed to reach the steady state.

This paper addresses the load testing of WS-BPEL compositions. For that, we developed WSCLT tool, which takes as input a specification of the composition under test, expressed as a Timed Automaton, and considers various parameters such as the number of requests to handle simultaneously. Our WSCLT tool injects this load in the application and monitors the sequence of requests, invocations and responses between the components. This log is then analyzed by the tool to separate the actions corresponding to each instance and to check that they follow legitimate paths. A global report is then issued regarding all concurrent instances. We illustrate how to use our prototype tool by means of a case study.

Radio communications are the most important sources of energy consumption in Wireless Sensor Networks (WSN). Optimizing the sensors transmitting power with keeping the required nodes average degree preserves significantly the sensors energy. In this paper, we analyze the optimal transmitting power needed by each sensor to reach a given average node degree in heterogeneous WSN. The problem that we aim solving in this paper is the following: given a set of heterogeneous sensors having various capabilities: weak nodes and strong nodes that are scattered randomly in a field according to a Poisson Point Process with densities λ 1 and λ 2 respectively. What is the optimal transmitting power needed by each sensor to ensure k-average degree? We investigate also a related problem: What has the most important effect on weak nodes transmitting power: The quantity of the strong nodes or their quality in terms of energy supply? Our analytical study has been validated with Monte-Carlo simulations.

We propose in this paper a new approach for conformance testing of WS-BPEL compositions. It is based on Timed Automata as model for testing WS-BPEL implementations, a distributed testing architecture and an algorithm for online test generation and execution. We also implemented our solution in the form of a prototype tool named WSCCT.
