ResouRCe

  • Wireless+Multi-Antenna+Channels+Modeling

    The explosion in demand for wireless services experienced over the past 20 years has put significant pressure on system designers to increase the capacity of the systems being deployed. While the spectral ResouRCe is very scarce and practically exhausted, the biggest possibilities are predicted to be in the areas of spectral reuse by unlicensed users or in exploiting the spatial dimension of the wireless channels. The former approach is now under intense development and is known as the cogni- tive radio approach (Haykin 2005).

  • Web Based Enterprise Energy

    HIS IS THE THIRD —and most likely the last—book in the series on information technology for energy managers and web based energy infor- mation and control systems. This book concentrates on web based enterprise energy and building automation systems, and serves as a capstone volume in this series. The thrust here is that the highest level functions of a building and facility automation system are provided by a web based EIS/ECS system that provides energy management, maintenance management, overall facility operational management, and ties in with the enterprise ResouRCe management system for the entire facility or the group of facilities being managed. If there were ever to be a fourth volume in this series, it would follow the logical progression of the first three volumes, and would probably be titled Web Based Enterprise ResouRCe Management Systems.

  • Cognitive+Radio+Networks

    ResouRCe allocation is an important issue in wireless communication networks. In recent decades, cognitive radio technology and cognitive radio-based networks have obtained more and more attention and have been well studied to improve spectrum utilization and to overcomethe problem of spectrum scarcity in future wireless com- munication systems. Many new challenges on ResouRCe allocation appear in cogni- tive radio-based networks. In this book, we focus on effective solutions to ResouRCe allocation in several important cognitive radio-based networks, including a cogni- tive radio-basedopportunisticspectrum access network, a cognitiveradio-basedcen- tralized network, a cognitive radio-based cellular network, a cognitive radio-based high-speed vehicle network, and a cognitive radio-based smart grid.

  • TCP-IP Socket網絡編程

    Internet-“冷戰”的產物-1957年10月和11月,前蘇聯先后有兩顆“Sputnik”衛星上天-1958年美國總統艾森豪威爾向美國國會提出建立DARPA(Defense Advanced Research Project Agency),即國防部高級研究計劃署,簡稱ARPA-1968年6月DARPA提出“資源共享計算機網絡”(ResouRCe Sharing Computer Networks),目的在于讓DARPA的所有電腦互連起來,這個網絡就叫做ARPAnet,即“阿帕網”,是Interne的最早雛形早期的ARPAnet使用網絡控制協議(Network Control Protocol,NCP),不能互聯不同類型的計算機和不同類型的操作系統,沒有糾錯功能1973年由Kahn和Vinton Cerf兩人合作為ARPAnet開發了新的互聯協議。1974年12月兩人正式發表第一份TCP協議詳細說明,但此協議有信包丟失時不能得到有效的糾正TCP協議分成了兩個不同的協議:-用來檢測網絡傳輸中差錯的傳輸控制協議TCP-專門負責對不同網絡進行互聯的互聯網協議IP從此TCP/IP協議誕生1983年ARPAnet上停止使用NCP,互聯網上的主機全部使用TCP/IP協議,TCP/IP協議成為Internet中的“世界語”
