NGWMN 2011 - Fourth International Workshop on Next Generation of Wireless and Mobile Networks (NGWMN-2011)

The next generation of wireless and mobile networks is expected to allow a single mobile user to access heterogeneous wireless and mobile networks. Since wireless cellular networks such as 3G systems (e.g., WCDMA, UMTA, cdma200, etc) and WLANs (e.g., IEEE 802.11a/b/e/g/n, WiMax, etc) are two typical existing networks, the integration and interoperability issues become new challenges. The internetworking of different types of wireless and mobile networks aims to provide seamless services for the mobile users among different type of networks. Due to the heterogeneity of different radio access techniques, different types of traffic and applications, Quality of Service (QoS) guarantee also becomes a critical issue for an integrated wireless and mobile network. Therefore, this workshop will provide a timely technical forum for the dissemination of new results in this exciting research area and is devoted to the architectures, protocols, resource management, mobility management, and scheduling in integrated wireless and mobile networks. Topics of interest include, but are not limited to:

Architecture of integrated heterogamous networks
Handoff and mobility management
Integration of heterogeneous networks
Resource management
Multi-interface access protocols
QoS provisioning
Cross-layer design and optimization
Load balancing and activity scheduling
MAC protocols
