Enhancing performance of IP service in HIPERLAN/2 networks

The demand for multimedia applications nowadays has driven the existing wireless IP technologies towards the direction of more robust and effective solutions. Performance enhancing proxies (PEPs) are featuring as a proper candidate in order to provide with the performance enhancements required The solution evaluated in this paper is a PEP, referred to as wireless adaptation layer (WAL), which aims at offering traffic differentiation and QoS improvements over a wide variety of existing wireless technologies, such as IEEE 802.11b, Bluetooth and HIPERLAN/2. Our focus is on the HIPERLAN/2 wireless infrastructure, which is tested with the presence of the WAL under various traffic conditions. A detailed simulation model shows the improvement in QoS offered by the WAL.
