Description: Advances of diverse wireless access technologies are
defining the trends of future wireless networks, named Next
Generation Wireless Networks (NGWN), where several access
technologies will coexist and devices will be equipped with
different network interfaces, in order to take advantage of each
access technology. In NGWN communication maintenance is a
concept willing to reach. Therefore, strategies to tackle
mobility and multihoming issues are required. In this paper we
propose an extension of HIP in order to cover challenges that
end to end mobility presents in NGWN. Our approach consists
on sending access technology related information before
handover execution occurs, in order to optimize handover
process. Moreover, the extension tackles QoS issues by sending
application requirements as well as restrictions or
improvements affecting its performance in the new access
technology. Platform: |

Description: WiMAX technology is presently one of the most promising global telecommunication systems.
Great hopes and important investments have been made for WiMAX, which is a Broadband
Wireless Access System having many applications: fi xed or last-mile wireless access,
backhauling, mobile cellular network, telemetering, etc. WiMAX is based on the IEEE 802.16
standard, having a rich set of features. This standard defi nes the Medium Access Layer and
the Physical Layer of a fi xed and mobile Broadband Wireless Access System. WiMAX is also
based on the WiMAX Forum documents.
This book is intended to be a complete introduction to the WiMAX System without having
the ambition to replace thousands of pages of documents of the IEEE 802.16 standard and
amendments and WiMAX Forum documents. There will always be a need to refer to these
for any technical development of a specifi c aspect of WiMAX. Platform: |

Description: "Advanced Wireless Networks 4G Technologies". New E-Book. In the wireless communications community we are witnessing more and more the existence
of the composite radio environment (CRE) and as a consequence the need for reconfigurability
concepts. The CRE assumes that different radio networks can be cooperating components
in a heterogeneous wireless access infrastructure, through which network providers
can more efficiently achieve the required capacity and quality of service (QoS) levels. Reconfigurability
enables terminals and network elements to dynamically select and adapt
to the most appropriate radio access technologies for handling conditions encountered in
specific service area regions and time zones of the day. Both concepts pose new requirements
on the management of wireless systems. Nowadays, a multiplicity of radio access
technology (RAT) standards are used in wireless communications. Platform: |

Description: Wireless Mesh Networks (WMNs) are a promising technology
for providing broadband wireless access to the end
user. They offer a higher degree of flexibility compared to
traditional networks but on the expense of a more complex
structure. Thus, planning and optimization of WMNs is a
challenge. In this paper, we address this challenge using
genetic algorithms. Genetic algorithms are able to evaluate
and optimize large-scale WMNs in relatively small computation
time. The results prove the effectiveness of the genetic
operators to optimize the routing and channel assignment in
WMNs. Platform: |
