Embodiment Construction

[0071] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0072] A method for sharing local cached files based on a mobile swarm intelligence network provided by the present invention comprises the following steps:

[0073] Step 1: Construct a user alliance pattern based on the swarm intelligence file sharing network based on the cooperative game model. The user alliance pattern is a collection of multiple user file sharing alliances formed by users; see figure 1 , its specific implementation includes the following sub-steps:

[0074] Step 1.1: Define a relationship to measure the pros and cons of alliance pattern ...

Abstract

The invention discloses a shared method of native cache file based on mobile intelligence network. First builds a user alliance pattern based on gunz file shared network through cooperative game model, the user alliance pattern shares allied gather for muti-user file for user; formulates a best file cache strategy and a file shared strategy fora specific user alliance by adopting the user alliance pattern; user downloads from base station corresponding proportional file to local mobile device by the file cache strategy and the file shared strategy. The shared method main forms the shared user alliance of file based on the intelligence network, reduces transmission delay through a local connectivity; a distributed arithmetic of the user alliance pattern is achieved and has unit reasonability, Dhp stability and agreement stability; introduces concept of file popularity index, confirms the best cache strategy through minimized total transmission delay of the user alliance, the mobile network transmission delay can be reduced.

Description

technical field [0001] The invention belongs to the technical field of mobile Internet, and in particular relates to a local cache file sharing method based on a mobile swarm intelligence network. Background technique [0002] Watching videos on mobile devices has become increasingly popular. According to Cisco's forecast for global mobile data traffic, mobile video traffic is growing exponentially and is expected to reach 9.9 exabytes per month in 2017. By 2020, video traffic will account for 72% of total traffic. Relying on the core network to work alone will be difficult and expensive to meet such a huge demand, and it is imperative to reduce the transmission delay of mobile video services. Technological advances that leverage the storage space of massive edge devices and short-range communications could provide a solution. Global mobile devices and access points are expected to reach 9 million, using their huge and low-cost storage space, and then realizing high-speed...
