Abstract

Current pervasive systems tend to consider security and QoS separately, ignoring the influence of each aspect on the other. This paper presents an adaptation model based on selection of component compositions enabling to capture dynamic and fine-grained trade-offs between both QoS and security in those systems. The model is multi-constraints and utility-based, and takes into account computing resources, the perceived risk level, and user preferences. We illustrate through a case study of a typical Beyond 3G adaptive multimedia streaming service how the model may be applied to find the right balance between different QoS and security dimensions.
