摘要:

随着异构网络融合和网络自适应化逐渐成为必然的发展趋势,认知无线网络随之出现,并提供了一种实现全局端到端目标优化的方法。认知无线网络由能自适应改变自身配置的网络设备组合而成,为设计灵活高效的拓扑策略提供了可能性和保障。提出了一种拓扑重构的控制策略,能够规划数据传输路由,在高效利用空闲频谱资源的同时,提升了传输的效率和性能。

Abstract:

Considering the inevitable trends for heterogeneous network convergence and self-adaptation ability,cognitive radio network(CRN)concept has been proposed with some essential characteristics to achieve global endto-end goals.CRN are composed of cognitive devices which have the capable of changing network configurations based on the dynamic environment.This capability opens up the possibility of designing flexible and dynamic topology control strategies with the purpose of opportunistically reusing idle licensed spectrum and effectively achieving data transmission.This work focuses on the problem of designing effective topology reconfiguration algorithm to offer optimal routing solutions.

Key words: cognitive radio network, reconfiguration, topology, heterogeneous network convergence
