Composable ad-hoc mobile services for universal interaction
Proceedings of the 3rd annual ACM IEEE international conference on Mobile computing and networking - MobiCom '97, 1997Co-Authors: Todd Davis Hodes, Edouard Servan-schreiber, Randy H Katz, Lawrence RoweAbstract:This paper introduces the notion of “universal interaction,” allowing a Device to adapt its functionality to exploit services it discovers as it moves into a new environment. Users wish to invoke services - such as controlling the lights, printing locally, or reconfiguring the location of DNS servers - from their mobile Devices. But aptiotistandardizationof interfaces and methods for service invocation is infeasible. Thus, the challenge is to develop a new service architecture that supports heterogeneity in Client Devices and controlled objects, and which makes minimal assumptions about standard interfaces and control protocols. There are five components to a comprehensive solution to this problem: 1) allowing Device mobility, 2) augmenting controllable objects to make them network-accessible, 3) building an underlying discovery architecture, 4) mapping between exported object inter- faces and Client Device controls, and 5) building complex behaviors from underlying composableobjects. We motivate the need for these components by using an ex- ample scenario to derive the design requirements for our mobile services architecture. We then present a prototype implementation of elements of the architecture and some example services using it, including controls to audio/visual equipment, extensible map- ping, server autoconfiguration, location tracking, and local printer access.

personalized multimedia services using a mobile service platform
Wireless Communications and Networking Conference, 2002Co-Authors: Yih Farn Chen, Huale Huang, Serban Jora, Rittwik Jana, S John, A Reibman, Bin WeiAbstract:In this paper we address the research issues in providing personalized multimedia services, which enable a mobile user to remotely record video programs, control cameras, and request the delivery of pre-recorded or live video content to his or her own mobile Device. We describe a mobile service platform that authenticates users who send service requests from various mobile Devices, transcodes video content based on user and Device profiles, and authorizes the delivery of content from a media server to the proper Client Device. The media server adapts automatically to the fluctuations of the wireless channel conditions for reasonable viewing on the Client Device. The mobile service platform essentially manages the control path, while the media server handles the actual content delivery. We discuss various aspects of the integration and report our successful experiments conducted on wireless LAN and CDPD networks.

volare context aware adaptive cloud service discovery for mobile systems
Adaptive and Reflective Middleware, 2010Co-Authors: Panagiotis Papakos, Licia Capra, David S. RosenblumAbstract:With the recent widespread use of smart mobile Devices, as well as the increasing availability of fast and reliable wireless Internet connections for mobile Devices, there is increased interest in mobile applications where the majority of the processing occurs on the server side. The flexibility, stability and scalability offered by cloud services make them an ideal architecture to use in Client applications in a resource limited mobile environment. This is because mobile application usage patterns tend to be uneven, with various usage spikes according to time and location. However, the mobile setting presents a set of new challenges that cloud service discovery methods developed for non-mobile environments cannot address. The requirements a mobile Client Device will have from a cloud service may change due to changes in the context of the Device, which may include hardware resources, environmental variables or user preferences. Binding to a service offering different quality of service levels from the ones required may lead to excess consumption of mobile resources such as battery life, as well as unnecessarily high provision costs. This paper introduces VOLARE, a middleware-based solution that monitors the resources and context of the Device, and dynamically adapts cloud service requests accordingly, at discovery time or at runtime. This approach will allow for more resource-efficient and reliable cloud service discovery, as well as significant cost savings at runtime.

L.: VOLARE: Adaptive web service discovery middleware for mobile systems
2009Co-Authors: Panagiotis Papakos, David S. Rosenblum, Arun Mukhija, Licia CapraAbstract:Abstract: With the recent advent and widespread use of smart mobile Devices, the flexibility and versatility offered by Service Oriented Architecture’s (SOA) makes it an ideal approach to use in the rapidly changing mobile environment. However, the mobile setting presents a set of new challenges that service discovery methods developed for nonmobile environments cannot address. The requirements a mobile Client Device will have from a Web service may change due to changes in the context or the resources of the Client Device. In a similar manner, a mobile Device that acts as a Web service provider will have different capabilities depending on its status, which may also change dramatically during runtime. This paper introduces VOLARE, a middleware-based solution that will monitor the resources and context of the Device, and adapt service requests accordingly. The same method will be used to adapt the Quality of Service (QoS) levels advertised by service providers, to realistically reflect each provider’s capabilities at any given moment. This approach will allow for more resource-efficient and accurate service discovery in mobile systems and will enable more reliable provider functionality in mobile Devices
