Heterogeneous Wireless Network is currently a major area of focus in communication engineering. But the important issue recent approachability to wireless networks while maintaining quality service. Today, all access are working tandem keep users always connected internet cloud that matches price affordability and performance goals. In order achieve seamless connectivity, due consideration has ...

Machine-to-machine (M2M) technology allows direct communications between machine devices through wireless and/or wired systems without human intervention, which opens unique opportunities to businesses as well as consumers on cost reduction and services improvement. It holds huge potential for applications in a wide range of industries. It has been expected that there will be a huge increase in...

Hybrid Wireless Mesh Network is a special case of infrastructural mesh network which utilizes heterogeneous wireless networks for communication. The integration of WMNs with other networks such as the Internet, cellular, IEEE 802.11, IEEE 802.15, IEEE 802.16, sensor networks, etc., can be accomplished through the gateway and bridging functions in the mesh routers. An integrated security mechani...

Currently, there are many wireless networks based on different radio access technologies (RATs). Despite this, new kind of networks will be developed to complement those already existing today. As there will be no RAT able to give users full service requirements with universal coverage, the next generation wireless networks will integrate multiple technologies, working jointly on a heterogeneou...

A key word describing next-generation wireless communications, so called 4G, is “seamless.” As part of the eJapan Plan promoted by the Japanese Government, the MIRAI (Multimedia Integrated network by Radio Access Innovation) project is aiming at the development of new technologies that will enable seamless integration of various wireless access systems for practical use by 2005. First, this pap...

Supporting quality of service (QoS) in wireless networks has been a very rich and interesting area of research. Many significant advances have been made in supporting QoS in single wireless networks. However, support for the QoS across multiple heterogeneous wireless networks will be required in the future wireless networks. In connections spanning multiple wireless networks, the end-to-end QoS...
