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.

[3G developadvanced-wireless-networks-4g-technologies.978047

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.

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.
