Embodiment Construction

[0034] exist figure 1 In the scenario of , the dotted frame represents the conference mode under the state of wireless ad hoc network. The two hosts directly connected to the projector are shared hosts, and other computers and PDAs are used as request service hosts due to their limited resources. When users request services, they send relevant information and data to the shared host by requesting the service host.

[0035] At the initial moment, the hosts form a wireless ad hoc network, and the hosts communicate in a wireless manner. Afterwards, the service discovery modules of each host in the wireless ad hoc network environment are in a normal working state. At this time, the shared host can issue services, and the service-requesting host can request and use projector services. When the information requested by the service requester is accepted, the service provider provides the service to the service requester. So far, the service discovery work is completed.

Abstract

A conference system achieves projector sharing based on service discovery, which comprises a projector, a sharing-type host machine and a service-request type host machine, wherein the sharing-type host machine is formed by a service discovery module, an information module, a service cooperation module and a service sharing module, and the service-request type host machine is formed by a service discovery module, a service request module and a data transmission module. The conference system discovers modules and dynamically refreshes information lists of a host machine based on the service of two types of host machines, achieves the distribution and request of service based on other modules of the two types of host machines, achieves information communication and service response between host machines based on the interwork of the two types of host machines, and solves the problem of service-request conflict in projector sharing through adopting a reasonable cooperation mechanism.

Description

technical field [0001] The invention relates to a projector sharing technology in computer science, in particular to a meeting system for realizing shared projectors through service discovery in a wireless ad hoc network. Background technique [0002] In a typical meeting room environment, users bring mobile devices into a wireless ad hoc network, and their available computing resources are often very limited. Therefore, the key issue of projector sharing is to cooperate with each other and use shared resources rationally. [0003] At present, the main ways to solve the problem of resource sharing in the conference system are: [0004] (1) Wireless projection access card technology [0005] The wireless projection access card is a wireless network projection management system, which adopts IEEE802.11g or IEEE802.11b wireless network, realizes wireless transmission of multimedia data and sharing of projectors, and ensures transmission quality. However, this technology cann...
