Flexible Simulation of Ubiquitous Computing Environments

Ubiquitous computing software must be reliable. As it occurs in conventional software, one of hardest tasks nowadays is testing. Moreover, if testing is focused on context-aware and adaptive services, the task is even harder. In this case, it is not sufficient testing the software in order to find bugs in the code and repair them (i.e. debugging) and, at the same time, checking that procedures and functions responses to specific interesting inputs are correct. It is also needed checking that the responses of services (i.e. the system under test) to changes in the environment are correct. And the environment includes also human users. This paper proposes UbikSim. An ubiquitous computing environments simulator which tries to alleviate the particularities of testing services and applications whose behaviour depends on both physical environment and users.
