The proliferation of mobile demands and increasingly multifarious services pose challenges to both the radio access networks (RANs) and the core network (CN). Unfortunately, the traditional networks can hardly meet the increasing requirements. Software-defined network (SDN) and network virtualization (NV) are considered as innovative paradigms to stress these problems. By extending SDN to wireless...
Vehicular communication network (VCN) with vehicles being mobile nodes in the last decade has received considerable attention both academia and industry. In VCN, vehicles are expected to be capable of communicating with other vehicles as well as stationary infrastructures, such as access points (APs). However, due to the limited coverage of APs, the fading characteristics of physical channel and the...
In next generation wireless network (NGWN), mobile users are capable of connecting to the core network through various heterogeneous wireless access networks, such as cellular network, wireless metropolitan area network (WMAN), wireless local area network (WLAN), and ad hoc network. NGWN is expected to provide high-bandwidth connectivity with guaranteed quality-of-service to mobile users in a seamless...

Vehicular Ad hoc Network (VANET) has recently received considerable attention both from academia and industry. In VANET, both safety related application and user application are expected to be supported through the communication between vehicles and access points (AP), To deal with the problem of short connectivity duration and low throughput of user service in VANET due to the mobility of vehicles...
