Future wireless networks will see a combination of 3G WWANs and WLANs, which provide data services at different rates and with different coverages. New handoff management schemes are required in such heterogeneous networks to ensure the continuation of application sessions with low handoff cost. This paper proposes a novel service-oriented vertical handoff scheme between 802.11b (WLAN) and cdma2000...
The enhancement of transmission speed of third generation cellular systems is yielded by packet scheduling techniques, which enlarge system capacity and improve bandwidth utilization by choosing the most suitable packet to be sent according to the instantaneous channel condition of mobile stations. However, since different types of traffic require different channel quality, considering the difference...
cdma2000 1xEV-DO revision A (DO Rev. A), also known as IS-856-A, is a third generation (3G) wireless solution to providing wide-area high-speed mobile Internet access with high spectral efficiency and advanced quality-of-service (QoS) support. In this paper we evaluate the reverse link performance improvement (in terms of coverage and data throughput) of IS-856-A with the use of more advanced antenna...
