摘    要:在认知无线Ad Hoc网络中,路由问题面临巨大挑战。由于各认知节点可用频谱的时变性、多样性和差异性,传统的路由尺度不再适用于认知无线Ad Hoc网络。本文在自组织认知网络环境下,应用主用户信道的使用模型,同时考虑次用户之间的干扰情况,提出了两类路由尺度和算法,仿真结果表明,这两类路由尺度都能很好地反映端到端性能。

关 键 词:认知无线电  Ad  Hoc  路由尺度  信干噪比  时延  平均吞吐量  泊松过程

Abstract:Routing in cognitive radio Ad Hoc networks faces great challenges.Because of the available spectrum of cognitive nodes is variability,diversity and difference,the traditional routing metrics no longer apply to the cognitive radio Ad Hoc networks.Considering the environment of cognitive self-organizing networks in this paper,we took the channel model of primary users and the interference between the secondary users into account and then we proposed two types of routing metrics.Simulation results indicate tha...
Keywords:cognitive radio  Ad Hoc  routing metric  SINR  delay  average throughput  Poisson process
