【摘要】：近年來,移動互聯網的需求迅速增長。例如高清在線視頻、實時游戲、高速下載等業(yè)務,需要高速率和低延遲的網絡通道。而LTE作為當前主流的4G網絡制式,可以滿足用戶接入網絡使用高速服務的需求。同時,無線網絡的能耗問題日益突出,其中LTE基站作為接入網消耗了無線蜂窩網的大部分能量;而用戶終端在進行高速數據處理時,過快地消耗了能量。因此,基站和終端節(jié)能成為了重要的研究課題。針對LTE基站節(jié)能的問題,本文提出了一種流量感知的節(jié)能資源分配算法。該算法針對具有不同流量特征的業(yè)務的服務質量需求,調整數據包的發(fā)送時機和發(fā)送數量,提高資源的使用效率。同時,本算法通過改變算法的參數來適配流量變化,可以在節(jié)能和性能之間取得較好的平衡。模擬實驗的結果表明,本算法在基站負載40%以下時,能夠以較少的資源獲得與其他算法相似的吞吐量。針對設備節(jié)能的問題,本文提出了一種LTE移動終端DRX節(jié)能因子自適應調整算法。本算法通過計算的方式,從機制的參數空間挑選合適的參數對節(jié)能因子進行適配,避免了對參數空間進行搜索帶來的開銷。同時,本算法改善了標準機制中節(jié)能因子受業(yè)務速率變化產生偏離的情況。模擬實驗的結果表明,本算法可以在維持節(jié)能因子在指定范圍的基礎上,獲得與標準機制相似的平均延遲和丟包率性能。
[Abstract]:In recent years, the demand for mobile Internet has been growing rapidly. For example, high-definition online video, real-time games, high-speed downloading and other services require high-speed and low-latency network channels. LTE is the current mainstream 4G network system. At the same time, the problem of energy consumption in wireless network becomes more and more serious, in which LTE base station as access network consumes most of the energy of wireless cellular network. The user terminal consumes energy too quickly in high-speed data processing. Therefore, the energy saving of base station and terminal has become an important research topic. In view of the problem of energy saving in LTE base station, In this paper, an efficient resource allocation algorithm for traffic awareness is proposed. The algorithm adjusts the sending time and the number of packets according to the QoS requirements of different traffic characteristics, and improves the efficiency of resource utilization. By changing the parameters of the algorithm to adapt to the change of flow, the algorithm can achieve a good balance between energy saving and performance. The simulation results show that the algorithm is less than 40% when the base station load is less than 40%. In order to solve the problem of equipment energy saving, this paper presents an adaptive adjustment algorithm for DRX energy saving factor of LTE mobile terminal. Selecting the appropriate parameters from the parameter space of the mechanism adapts to the energy saving factor, which avoids the cost of searching the parameter space. At the same time, The algorithm improves the deviation of energy saving factor from the change of service rate in the standard mechanism. The simulation results show that the algorithm can maintain the energy saving factor in a specified range. The average delay and packet loss performance similar to the standard mechanism is obtained.
