Energy Aware Caching Content Distribution Scheme: Research And Realization

In recent years,with the popularity of intelligent terminal and the development of mobile social network,the quantity of mobile devices and mobile data requests grow rapidly,especially the growth of the video data,leading to the tension of spectrum and the increasement of energy consumption of mobile communication.Therefore,it is necessary to provide efficient and low-energy content distribution schemes,to reduce the consumption of network bandwidth and battery power of mobile devices as much as possible under the premise of satisfying user experience quality.With the development of the local communication technologies such as Devices-to-Devices,which is referred to as D2 D,content distribution scheme based on this way of communication has become a research hotspot nowadays.In addition,as the cache capacity of the mobile devices increases,the cache space for reducing energy consumption is also a feasible scheme,therefore,this dissertation has proposed a new Energy Aware Caching Content Distribution,which is referred to as EACCD,the scheme using the D2 D communication technology and mobile device cache capacity,reducing the energy consumption in the process of content distribution.First of all,divide the mobile users in the community,and choose the community agency,considering the user's location distribution characteristics and the same interest of popular video,relay agent selection algorithm based on cache strategy has proposed,relay agents is responsible for obtaining data from the base station and into the buffer,other members directly downloading the content of interest from the agent's buffers through the D2 D communication.In this dissertation,through the simulation experiments of EACCD comparing with different content distribution scheme,and on the contrast experiment of different parameters,analysis of the variable parameter of different values for the effects of saving energy consumption,for the actual situation of different distributed decision-making to provide theoretical basis for using scene,in the end,based on the MATLAB GUI(Graphical User Interface)platform realizes EACCD,to assist the user to do distributed decision making.
