摘要
基于数据提供者的移动节点在网络中的不同位置及不同移动速度,结合命名数据网络(NDN)请求者驱动的数据传输模式,提出了3类NDN移动支持策略的网络能耗解析表达式,为NDN移动网络的研究提供了形式化的建模方法.对这3类移动支持策略在不同场景下能耗的分析与比较结果表明,数据流行度分布、移动节点所处位置及移动速度对策略的能耗影响不尽相同,为后续探求最优能效的移动支持策略提供了理论参考.
Based on different locations and speeds of mobile nodes of data providers in network,combined with named data networking( NDN) requester driven data transmission mode,analytic expressions of network energy consumption of 3 types of NDN mobile support strategies are proposed,which provide a formal modeling method for the study of NDN mobile network. By analyzing and comparing the energy consumption of these 3 mobile support strategies in different scenarios,data popularity distribution,location of mobile nodes and moving speed have different effects on energy consumption of the 3 strategies. It provides a theoretical reference for exploring the optimal energy efficiency mobile support strategies in the future.
