Wireless Internet Protocol

Abstract: A method and system for location-aware wireless mobile devices including a mobile user network interfaces and protocol. A network-independent location-aware network protocol provides communication with location-aware wireless mobile devices. The protocol is network-independent to support and deliver location-aware services over virtually any wireless or wired network transparently regardless of the protocols being used on a transport network. The protocol is location-aware of current geographic locations of plural wireless mobile devices. Alert information is provided to a location-aware wireless mobile device with the network-independent location-aware network protocol and interfaces. Location-aware wireless mobile devices are located and provided with alert information with the network-independent location-aware network protocol and interfaces. The method, system, interfaces and protocol may help improve usability of mobile devices by allowing the mobile devices to be location-aware.

Abstract: This book provides a preview of emerging wireless technologies and their architectural impact on the future mobile Internet. The reader will find an overview of architectural considerations for the mobile Internet, along with more detailed technical discussion of new protocol concepts currently being considered at the research stage. The first chapter starts with a discussion of anticipated mobile/wireless usage scenarios, leading to an identification of new protocol features for the future Internet. This is followed by several chapters that provide in-depth coverage of next-generation wireless standards, ad hoc and mesh network protocols, opportunistic delivery and delay tolerant networks, sensor network architectures and protocols, cognitive radio networks, vehicular networks, security and privacy, and experimental systems for future Internet research. Each of these contributed chapters includes a discussion of new networking requirements for the wireless scenario under consideration, architectural concepts, and specific protocol designs, many still at research stage.

Abstract: In the field of Quality-of-Service (QoS) management for adaptive real-time services running on mobile devices which support different access technologies in dynamic wireless Internet Protocol (IP) networks, the connectivity of the applied nodes is unpredictable time-varying. In this context, a QoS management unit (304) is proposed that allows adaptive applications with real-time requirements in typical mobile wireless scenarios—e.g. a radio link with a changing transmission quality and handover procedures (2900)—to adaptively and responsively react to a time-varying network topology and different radio link characteristics. Said QoS management unit (304) provides methods of pre-allocating, reserving, monitoring and adapting QoS-related parameters in a dynamic mobile environment. The QoS management unit (304) comprises at least one analysis unit (306) which evaluates QoS requests received from other nodes (402 a/b , 404) to inform the application unit (328) of said mobile terminal (208) about the current QoS situation, at least one processing unit (312) that manages request messages (1200, 2000, 2400) for each type of QoS request, at least one monitoring unit (318) which monitors the current QoS situation within said mobile node (208) and initiates requests by activating the processing unit (312), and at least one generation unit (322) which is responsible for generating QoS requests or passing them on to the QoS management units (304) of other nodes (402 a+b , 404).

Abstract: Over the last decade, the tremendous growth in the mobile Internet user population has been accompanied by an equally exciting evolution in wireless data networks. However, quite understandably, the evolution has been distinctly characterized by an increasing degree of heterogeneity along several dimensions such as the access technology, network model, device, and application requirements. This heterogeneity, in turn, imposes a significant challenge on the design of the network protocol stack, and leads to the question: how can the protocol stack at a mobile host cater effectively to the heterogeneous characteristics of the operating environment? In this article we provide an overview of AdaptNet, an adaptive protocol suite for next-generation wireless data networks. AdaptNet consists of protocol solutions at different layers of the protocol stack addressing several problems, including rate adaptation, congestion control, mobility support, and coding. A common underlying theme in the design of the protocols in the AdaptNet suite is adaptiveness to the operating environment. Through high-level discussions, preliminary results, and pointers to relevant related work, we show how AdaptNet achieves the goal of effectively addressing heterogeneity in next-generation wireless data networks.
