TCP_Performance_Over_Wireless_Network.rar - Transmission Control Protocol (TCP) is the dominant transport protocol in the Internet and
supports many of the most popular Internet applications, such as the World Wide Web (WWW),
file transfer and e-mail. TCP congestion control algorithms dynamically learn the network
bandwidth and delay characteristics of a network and adapt its performance to changes in traffic
so as to avoid network collapse.,2010-02-25 03:32:11,下载4次
jen_hall.rar - The need for robust access control mechanisms is paramount, especially in Wireless
Local Area Network (WLAN)s and Wireless Wide Area Network (WWAN)s. Current
authentication systems are vulnerable to device impersonation by rogue devices.
Within cellular mobile networks, this threat is actualized by cloning cell phones,
and using the clones for obtaining free services. A well known example in Wireless
Fidelity (WiFi)/802.11 networks is Media Access Control (MAC) address spoofing.
In this case, an attacker captures the MAC address of an authorized device and
programs it into his device, in order to obtain unauthorized access. The threat of
address spoofing is equally applicable to Bluetooth (BT) ad-hoc networks.,2010-02-25 03:22:13,下载4次
T2376.rar - The main objective of the project was to address the above
mentioned trends and to form a consistent concept of an All-IP telecommunications
network with wireless access. The project took into account both the user’ s and the
network’ s perspectives. In particular, the following areas have been addressed:
• existing implementations and concepts of All-IP wireless networks
• resource allocation and management in wireless systems, both existing and
planned
14
• traffic management and modelling, with special focus paid to the IP-based
services
• modelling for radio wave propagation
• positioning in wireless systems, especially for indoor environment
• network architectures and configurations, including mobile solutions
• dependability studies
• human-technology interaction.,2010-02-25 03:11:55,下载10次
5989-8309EN.rar - This application note is intended for engineers developing and testing mobile or
subscriber stations (MS or SS) and their components, based on the IEEE 802.16e
orthogonal frequency division multiple access (OFDMA) amendment to the 802.16-2004
standard. These devices are intended for the Mobile WiMAX market.,2010-02-25 03:03:46,下载9次
WiMAX_Technology_for_Broadband_Wireless_Access.ra - WiMAX technology is presently one of the most promising global telecommunication systems.
Great hopes and important investments have been made for WiMAX, which is a Broadband
Wireless Access System having many applications: fi xed or last-mile wireless access,
backhauling, mobile cellular network, telemetering, etc. WiMAX is based on the IEEE 802.16
standard, having a rich set of features. This standard defi nes the Medium Access Layer and
the Physical Layer of a fi xed and mobile Broadband Wireless Access System. WiMAX is also
based on the WiMAX Forum documents.
This book is intended to be a complete introduction to the WiMAX System without having
the ambition to replace thousands of pages of documents of the IEEE 802.16 standard and
amendments and WiMAX Forum documents. There will always be a need to refer to these
for any technical development of a specifi c aspect of WiMAX.,2010-02-25 02:44:03,下载24次
