The dynamic composition of systems of networked appliances, or virtual devices, in MANETs, enables users to generate, on-the-fly, complex strong specific systems. Current work in the development of service composition architectures in MANETs has yet to address QoS metrics for enhanced composition from a virtual device perspective. In this paper, we present an extension to a prominent dynamic broker-based distributed service composition protocol, embedding in a distributed manner, a QoS model providing compositions that form the best possible virtual device at the time of need. Simulation results show that our protocol extension provides a high increase in QoS at a low cost in terms of increased amounts of messages and composition time.
