Software Defined Networking (SDN) is an emerging paradigm to address the demands for flexible and agile network controllability. The fundamental idea of SDN is the physical separation of the network control plane from the data (forwarding) plane. This migration of control into programmable computing devices enables the underlying network infrastructures to be abstracted for applications and services...
Wireless Mesh Networks (WMNs) support the cost-effective broadband access for Internet users. Although today's IEEE 802.11 PHY and MAC specifications provide multi-channel and multi-rate capabilities, exploiting available channels and data rates is a critical issue to guarantee high network performance. In multi-rate wireless networks, high-rate links heavily suffer from performance degradation due...
With the rapid growth of mobile Internet, offering seamless connectivity and high-speed multimedia services in different types of wireless networks are important features in next generation wireless networks (4G networks). Many researchers envision that the 4G networks will consist of many radio access technologies which integrate into all IP-based networks while providing seamless handoffs across...
To provide Internet connectivity to mobile ad hoc networks, several solutions have been proposed. Most of the proposals focus on the suitable and optimal gateway selection and handover schemes in accordance with the network status and node mobility. However, since an integration of the Internet and ad hoc networks is a function of the network layer, they do not consider characteristics of lower layers...
The IEEE 802.16e system supporting mobility on fixed wireless-MAN systems is supposed to be a mobile broadband wireless access (BWA) and evolve into 4G mobile communication systems. Although the system already defines its own mobility management algorithm, a network layer handover algorithm should be defined to support the mobility of mobile stations in the Internet. There are many active researches...
