Topic: Resource Mobility and Interference Management for Heterogeneous Wireless and Cellular Networks Abstract: Heterogeneous wireless and cellular networks (HWNs and HetNets) are the basic formats for the Ubiquitous Communications in dynamic nomadic and mobile environments. Each user (with a smartphone, iPad, or PC）and/or each information flow can access and cross over different kind of wireless networks such as 2G/3G/4G mobile cellular networks, IEEE 802.11b/n/g/ac/ad WiFi networks, ad hoc networks, etc. To manage these diverse resources, the theory and architecture of resource mobility, and resource control algorithms based on resource flow are proposed. Based on these algorithms, the QoS of Information Flows can be assured. To increase the transmission capacity of high density HetNets, the different interference management schemes such as interference migration, mitigation and alignment are discussed. By combing interference management with the resource flow control, the user experiences in Ubiquitous Communications can be greatly enhanced.
