Performance of TCP/IP Over Next Generation Broadband Wireless Access Networks

چکیده
This paper presents performance evaluation results for Internet access over the next generation of broadband wireless access networks (2G-BWA). The challenge for these, mostly fixed access technologies stems from non line-of-sight deployment with high coverage and spectrum efficiency combined with link performance comparable to that of competing wired technologies (DSL, Cable modem). We present an overview of the features at the physical (PHY) and medium access control (MAC) layers which are key to a successful 2G-BWA design and demonstrate the impact of such features on end-to-end link performance with typical TCP/IP applications and wireless channel models.

Performance Evaluation of UMTS for Mobile Internet Access
UMTS constitutes the third generation of cellular wireless networks which aims to provide high-speed data access along with real time voice calls (Holma & Toskala, 2001). Wireless data is one of the major boosters of wireless communications and one of the main challenges of next generation standards (Chaudhury & Mohr, 1999). It can provide maximum data-rates ranging from 64kb/s to 2Mb/s in diff...

متن کاملA Seamless Handover Mechanism for IEEE 802.16e Broadband Wireless Access
Handover is one of the most important factors that may degrade the performance of TCP connections and real-time applications in wireless data networks. We developed a loss-free handover scheme called LPM (Last Packet Marking) for IEEE 802.16e-based broadband wireless access networks. By integrating MAC and network layer handovers efficiently, LPM minimizes the handover delay and eliminates pack...
