On the one hand, For information sensitivity of the sensor network, we design the mobile terminal through the gateway access authentication protocol, and effective solute the authentication and infbnnation between mobile devices and gateways, gateway and sensor network nodes obtain permission problem; on the other hand, according to the practical application of mobile information collection characteristics, the paper proposed information collection strategy based on historical data movement path to solve the problem for too long the device connection is established when the mobile smart devices collecting information along fixed lines, increasing the actual data transmission time and improve the efficiency of information transmission.展开更多

It takes the innovative service program based on an IC2 conceptualized program at Shanghai Jiao Tong University Library(thereafter abbreviated as SJTUL) as a concrete example to elucidate the merit of such an endeavor. Specifically, this paper discusses the particular development background, overall objectives and service contents of the IC2 motivated program at SJTUL. By presenting a detailed account of some of the key measures, major achievements and also possible future directions of library service development under the guiding principles of SJTUL's IC2 program, these authors hope that its innovative library practice may serve as a reference for other academic librarians to gain some inspirations for their own parallel service innovations or refinement focused on subject-oriented library liaison service to their constituents and parent institution's curricula and research projects.展开更多

文摘This paper stipulates that the subject-based library liaison service to a university's teaching and research programs with certain embedded distinctive features should become the mainstream modus operandi of its library service.
