Research On Auxiliary Content Distribution Based On OPNET On Campus

The extensive application of mobile communication technology provides campus students with convenient content distribution services.Students can use mobile data traffic to quickly acquire and transmit images,videos,audio,and other data on campus.However,the high cost of mobile data traffic is difficult to meet the needs of students for larger file sharing and downloading.The construction of WiFi-based wireless local area network on campus has also greatly improved the convenience of teachers and students accessing the Internet to obtain information.However,WiFi coverage is relatively small,and most campuses have not achieved full school coverage.Bluetooth-based short-distance communication technology facilitates the transfer and sharing of resource files among students.However,Bluetooth usually has no networking and routing.Even if students turn on Bluetooth,they cannot determine whether the connected party has the resources they need.It can be seen that the common content acquisition methods on campus are difficult to meet the students' needs for resource content in a timely manner.The widespread use of mobile smart terminals has accelerated the construction and development of campus networks.Under the campus network environment,it can use the widely used mobile intelligent terminal devices to achieve the expansion of network coverage.At the same time,mobile smart terminals can be used to enhance the campus resource sharing service capabilities,enabling students to share and download resource content at a lower cost on campus.This paper combines mobile communication technology with short-range communication technology based on Bluetooth technology.A content-distribution network framework for campuses is proposed by using a mobile communication network and a portable smart terminal to communicate in a mixed manner.This new content distribution solution is suitable for the actual needs and application characteristics of student users on campus.It provides content distribution services on campus in a low-cost,high-coverage manner.It promotes the construction of campus information.Finally,we combine the characteristics of the actual campus environment.On the OPNET simulation platform,the auxiliary content distribution scheme proposed in this paper is modeled and simulated.Experiments build different network topologies and distribute different types and sizes of resource content.The efficiency of content distribution under different experimental scenarios was compared and analyzed.We strive to provide a theoretical basis for the specific implementation of the program.The content distribution scheme is more suitable for content distribution requirements in the campus environment.As a result,it helps improve the content distribution efficiency of the campus network environment.
