To allow a seamless integration between wireless LANs and Wireless WANs, we developed a full stack adaptation model and a simple subnet architecture that superimposes Mobile-IP on cellular-type wireless LANs. The idea is to use Mobile IP as an integrative layer atop different LAN/WAN networks. While Mobile-IP is widely used in wireless WANs, it is not known how well it performs under a wireless...

In this paper an overview of the wireless local area network (LAN) area is provided. The two types of wireless LAN topologies used today, infrastructure and ad hoc, are presented. The requirements that a wireless LAN is expected to meet are discussed. These requirements impact on the implementation of both the Physical and MAC layer of a wireless LAN. The unique characteristics of wireless phys...

—Handover of Mobile Equipment (ME) between different Access Points (APs) is an inevitable problem in the wireless network. Mobility of the mobile equipment can cause degradation of Quality of Service (QoS). How to satisfy the user's QoS and achieve seamless handover becomes a very worth of study in the field of wireless communication network. In this paper, we proposed a handover management sc...

This thesis is devoted to improve the service performance for the multimedia traffics in wireless LAN networks. Review of TCP/IP model and Wireless LAN are conducted. An abstract model of network mobility framework is achieved based on investigating the state of art of mobility support. By the analysis of this model, we propose a new Xcast based scheme (X&M) to improve the deficiencies of Mobil...

mobility and portability with high-bandwidth data, voice, and video access. This has led to the introduction of wireless LAN technologies, which attempt to provide exactly that. In the 2.4 GHz frequency band, IEEE 802.11b is “the” wireless LAN solution in the market. However the 5 GHz frequency has two possible contending technologies — IEEE 802.11a and HiperLAN2. This white paper explains the ...

Wireless LAN hotspots are becoming widely spread. This, combined with the availability of new multi-mode terminals integrating heterogeneous technologies, opens new business opportunities for Mobile Operators. Scenarios in which 3G coverage is complemented by Wireless LAN deployments are becoming available. Therefore all IP based networks are ready to offer a new variety of services across hete...
