Case study of a multimedia wireless system

We present an experimental report of a multimedia wireless system with secure delivery of multimodal services to end-users over voice and data converged networks. Our design leads to an easily adaptable and extensible system architecture, in which system components interact with each other through loosely coupled interfaces based on asynchronous exchange of messages. It effectively separates service logic from service delivery, through the introduction of a secure broker between the end user devices and the enterprise level application that contains the service logic. This separation also provides additional levels of security and reliability at the application level. This work describes our system implementation and its performance results.
