Supporting high quality multimedia streaming on wireless devices poses several challenges compared to wired networks due to\nthe high variance in network performance encountered in the mobile environment. Although rate adaptation is commonly used in\nmultimedia applications to compensate for fluctuations in network performance, it is a reactive mechanism which is not aware of\nthe frequently changing connectivity that may occur on mobile devices. This paper proposed a performance evaluation model\nfor multimedia streaming applications that is aware of user mobility and network performance. We presented an example of\nmathematical solution to the model and demonstrated the functionality using common mobility and connectivity examples that\nmay be found in an urban environment.The proposed model is evaluated based on this functionality and how it may be used to\nenhance application performance.
