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...
Container transportation has become the main transportation form for international freight. In this paper, the energy saving and reliability tactics are considered and we design a new E-ZBR routing algorithm based on the original ZBR routing protocol. Firstly we propose the score criterion for estimating a path, and then based on nodes' connectivity, we select two existed better routing paths through...
To reduce the energy consumption of the LTE-A system, a distributed energy-saving mechanism based on CoMP (CoMP-DESM) is proposed to solve the inadequate coverage problem under the dormant cells. First, the network is divided into clusters based on the equivalent cell principle. Then, we transfer global optimization into a group of subproblems. Second, a joint processing- based cooperative cell selection...
With the rapid development of cellular network systems, the operators need more experience to deal with complicated network management system and wide range of Key Performance Indicators (KPIs). There are many indicators related to each other due to the definition or communication process. But several implicit associations still exist among these KPIs. This paper proposes an approach to figure out...
The paper introduced recursive algorithm of fractal graphics, put forward fractal graphics parallel algorithm. Analyzing recursive algorithmic time complexity and speedup rate of the parallel algorithm. The experimental results of PC cluster show that the theoretical analysis and the experimental results of fractal graphics parallel algorithm are consistency with a marked speedup rate.
