Efficient mobility management is one of the major challenges for next-generation mobile systems. Indeed, a mobile node (MN) within an access network may cause excessive signaling t...
Abstract. IEEE 802.16, also known as WiMAX, is a new wireless access technology for currently increasing demand of wireless high-speed broadband service. Efficient and effective d...
— The combined MIMO with Adaptive Modulation and Coding (AMC) technology can provide high spectral efficiency and link robustness. Moreover, the diversity-multiplexing tradeoff ...
Based on loosely coupled services in an XML engine, we describe how to realize fine-grained lock protocols, which can guarantee transaction isolation for applications using differ...
