| 摘 要： | 针对由认知无线电组成的Ad hoc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.

| 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 and routing is presented. |
