摘要 在一个移动 ad hoc 网络中移动节点的移动性和资源约束可能会导致网络分区或性能退化。提出了几种数据复制技术，尽量减少性能退化。其中大多数假设所有移动节点进行充分协作共同分担他们的内存空间。在现实中，但是，一些节点可能会自私地决定只有部分，或根本不与其他节点进行合作。这些自私的节点就可以减少总体网络中的数据可访问性。在此文件中，我们检查自私的副本分配视角移动 ad hoc 网络中节点的影响。我们长期在这种自私的副本分配。尤其是，我们开发一种自私的节点检测算法，认为部分自私和新颖副本分配技术来适当应付自私副本分配。进行的模拟演示拟议的办法在性能上优于传统合作副本分配技术在数据可访问性、 沟通成本和平均查询延迟。

WiMAX, or the IEEE 802.16 standard for broadband wireless access, is increasingly gaining in popularity as a technology with significant market potential. This paper first provides an overview of the existing and developing 802.16 standards and their key differences/applications. The PHY and MAC layers of a typical WiMAX base station are then described. The associated implementation challenges faced by WiMAX infrastructure developers, including performance/cost/flexibility trade-offs in the choice of silicon, are clearly outlined. The paper then describes how FPGA-based system implementation can address these challenges including the “accelerated time-to-market” requirement which is considered a key enabler for early success in this market. As an example design, the physical layer implementation of the 802.16d standard with Altera FPGAs and intellectual property (IP) is proposed.
