On-Access-Point-Selection-in-IEEE-802.11Wireless-
- In wireless local area networks often a station can potentially associate with more than one access point. Therefore, a relevant question is which access point to select “ best” from a list of candidate ones. In IEEE 802.11, the user
Videocodingwithh.264
- H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression ef

- Analysis of Card Log . Rev.C. By card log we mean the data captured using a logging program between the STB and the Card . The better logging programs to use are raw data loggers ( such as MacLog etc..) as they do not filter out anything as the
PARM_AINA_2006
- Current Peer-to-Peer (P2P) systems were developed and implemented as a result of a direct requirement/demand without an overall functional architecture. This makes the performance of the resulting systems far from optimal because other aspects
Topology_aware_ICC_2005
- One of the major weaknesses of existing peer-to-peer (P2P) networks is that their overlay structures do not correlate to the physical underlying network topology. As a result, the overlays waste network resources and introduce excessive end-toe
THE_FAST_HANDOVER_RESEARCH_of_wimax_network
- 本文正是在研究WIMAX/802.16e协议和FMIPv6协议的基础之 上，提出了基于FMIPv6的WIMAX网络快速切换机制，该方案采用跨 层切换的思想，MAC层联合网络层同时进行切换，在链路尚未断开 之前即完成新转交地址(NCOA)获取等功能，从而加快了切换进程， 减小了切换时延和切换时的丢包率。在提出本切换机制的基础上，本 文在NSZ仿真平台上对所提出的切换方案做了系统性的性能仿真，通 过仿真结果验证了方案的可行性和优越性。 - In this paper
