Abstract
The next generation of wireless access technologies cannot succeed by
providing either high data rates or full mobility support. Instead, it will be
required to provide both broadband connectivity and support for full
mobility. Worldwide Interoperability for Microwave Access (WiMAX) and High
Speed Packet Access (HSPA) are two upcoming technologies, which can live up to
these high expectations. In this master's thesis, WiMAX and HSPA are
reviewed, paying special attention to mobility management issues and support
for modern mixed multimedia traffic. In order to observe the real performance
of currently available commercial equipment under such traffic
conditions, measurement results from a WiMAX testbed are provided. These
results show that even with rudimentary fixed WiMAX equipment, the
effective capacity of the wireless link is substantially higher than that of
the wireless access technologies currently dominating the markets.
Wireless access technologies often need assistance from network layer
protocols, in order to deliver full mobility support at the system level. In
WiMAX, the Mobile Internet Protocol (MIP) is used for network layer mobility
management. This master's thesis overviews different MIP variants, including
the Mobile Internet Protocol Version 6 (MIPv6), which is reviewed in detail.
The handover latencies of the MIPv6 are also studied using a testbed.
The measurement results show that in order for the MIPv6 to handle network
layer mobility management in a satisfactory manner, all the wireless networks
involved in a handover must be carefully configured.
