To reduce the energy consumption in heterogeneous 5G access networks, we propose a cooperative energy-saving mechanism based on user association (UA-CESM). Joint processing (JP) and centralized resource scheduling are introduced into the mechanism to solve inadequate coverage problem caused by base-station (BS) dormancy by means of cooperative BS selection and BS state control. First, the number of...
Regarding the problems such as long response time, unbalanced job scheduling load and low implementation efficiency of traditional distributed logistics inventory system, this article proposed the Hadoop dynamic load balance scheduling algorithm based on heartbeat feedback. According to Hadoop scheduling model and working principle of cloud computing, it analyzed the map and reducer function role...
Power models are crucial to assess the power consumption of base stations (BSs) without quantitive description. Currently available models seldom consider the dynamic factors such as indoor and outdoor temperature. As power model will affect the energy-saving gains of different green resolutions, in this paper we provide such power models for mobile communication BSs relying on practical data collected...
Load balancing is one of the key target of LTE Self-Optimization Network (SON). In this paper, we propose a load balancing method for LTE downlink network, namely Load Vector Minimization based Load Balancing (LVMLB) method. Load Vector (LV) is a vector whose elements are the load values of cells and sorted in descending order. The order of LVs is defined by the lexicographical order. The smaller...
As a major part of wireless network optimization, load balancing can make the BS's resource utilization more reasonable. This paper proposes a load-balancing strategy based on Coordinated Multiple Points (CoMP) transmission/reception among the Base Stations (BS). To use universally, different patterns of load-balancing based on CoMP are modeled and discussed. We define call blocking rate as the QoS...
With the rapid growth of mobile communications, deployment and maintenance of cellular mobile networks are becoming more and more complex, time consuming, and expensive. In order to meet the requirements of network operators and service providers, the telecommunication industry and international standardization bodies have recently paid intensive attention to the research and development of self-organizing...
