The dynamic composition of systems of networked appliances, or virtual devices, enables users to generate complex strong specific systems. Current prominent MANET-based composition schemes make use of service discovery mechanisms dependent on periodic service advertising by controlled broadcast, resulting in the unnecessary depletion of node resources (i.e. battery and processing power). Moreover, current schemes do not allow for the protection of private or security sensitive information in the process of composition. The authors present a distributed constraint satisfaction problem for virtual device composition in MANETs addressing these issues, and through simulation show its high efficiency and QoS-awareness.
