摘要
针对终端通信接入网带宽、资源耗费以及频率等参数难捕捉,导致接入网切换失败率高的问题,提出一种基于ROF的接入网切换算法来实现有效解决。建立切换时网络带宽、资源耗费的代价函数,求解接入网与待接入网间最为合理的代价比例关系。为满足接入网络的硬性带宽需求,初始化请求矩阵,计算每次请求时接入网络产生的带宽变化,用于约束切换精准度,将ROF射频信号技术与判决指标相结合,运用ROF查找通信接入网的切换带宽和频率参数,选择最佳切换值,由此实现终端通信接入网有效切换。实验结果表明,所提算法能够运用较少的切换次数实现最佳切换,其不易受环境噪声影响,所需耗用较低。
This paper puts forward a handover algorithm for access networks based on ROF to effectively solve the problem of high failure rate of access network switching.Firstly,we established the cost function of network bandwidth and resource consumption during handover,and solved the most reasonable cost proportion between the access network and the network to be accessed.In order to meet the strict bandwidth requirements of access networks,we initialized the request matrix and calculated the bandwidth change generated by accessing the network for each request,and then used it to constrain the handover accuracy.Moreover,we combined ROF RF signal technology with the judgment indicators and used ROF to find the handover bandwidth and frequency parameters of the communication access network.Finally,we selected the best handover value,thus achieving an effective handover of the terminal communication access network.Experimental results show that the proposed algorithm can achieve optimal handover with less time,is not vulnerable to environmental noise and requires less consumption.
