摘    要:
针对由认知无线电组成的Adhoc网络中的频谱共享提出了一个跨层方案。通过综合考虑认知用户之间的干扰约束和流量需求,特别考虑到用户双向连接以及信道的非均匀性,以BFP(bandwidth—footprint-product)值最小为目,建立了一个二进制整数线性规划(BILP)模型。仿真结果给出了最优的频带分配和路由选择方案。

关 键 词:认知无线电  Ad  Hoc网络  频谱共享  非均匀信道

Abstract:
A cross-layer optimization approach to the spectrum sharing in cognitive radio based Ad Hoc network is proposed. Jointly considering interference constraints among cognitive radio users and rate demand, especially considering bi-directional links and the channel heterogeneity, the optimization problem is formulated in the form of binary integer linear programming (BILP) with the objective of minimizing the total BFP( bandwidth-footprint product), and the optimal spectrum sharing
Keywords:cognitive radio  Ad hoc networks  spectrum sharing  heterogeneous and routing is presented. channels
