摘要
提出一种将舰船通信资源分配与切换调度问题进行综合解决的方法,针对微基站与宏基站组建的网络环境,设计基于能效的舰船通信资源分配与切换调度的数学模型,将通信能效最大化作为目的,把数学模型转换成舰船通信资源分配与切换调度2个子问题。切换调度问题中,利用分析和推论获得微基站的睡眠模式决定条件,构建了微基站睡眠的用户调度流程,并与舰船通信资源分配流程结合,获得联合舰船通信资源分配与切换调度方法,实现数学模型求解,并提高运行最优能效和降低了时延。实验表明,相比当前方法,所提方法可节省约3–5倍的运行时间,能效可提高将近40%,不仅提高了舰船通信资源分配与切换调度的能效,还有效解决了运行时延高的问题。
In this paper, a method of synthetically solving the problem of ship communication resource allocation and handover scheduling is proposed. In the process, a mathematical model of ship communication resource allocation and handover scheduling based on energy efficiency is designed for the network environment between micro base station and macro base station. For the purpose of maximizing communication energy efficiency, the mathematical model is transformed into two sub-problems: ship communication resource allocation and handover scheduling. In the switching scheduling problem, Based on the analysis and inference, the sleep mode determinants of microbase stations are constructed. The user scheduling process of microbase station sleep, and combined with the ship communication resource allocation process, the combined ship communication resource allocation and handover scheduling method is obtained, the mathematical model is solved, and the optimal energy efficiency is improved and the delay is reduced. Experimental results show that compared with the current method, the proposed method can save about 3–5 times the running time, and the energy efficiency can be improved by nearly 40 times. It not only improves the efficiency of ship communication resource allocation and handover scheduling, but also effectively solves the problem of high running delay.
