A Loading-Balancing Framework for Distributed WebGIS Based on Multi-Agent
Xiao Weny · Journal of Henan Normal University · 2015
With the development of distributed WebGIS,the contradiction between massive data and the limited bandwidth is serious,this paper in vestigated both advantages and disadvantages of current WebGIS architecture.Combined with the Multi-Agent technology in the field of Distributed WebGIS,we put forward a kind of WebGIS framework based on Hybrid Strategy.Based on the analysis of the characteristics of the vast amounts of network data inquiry,this paper filters and refines the query data,and then presents a vector data query method using of cost function.Finally,It proved that the new framework was effective on improving the inquiry speed,saving bandwidth resources and maintaining agood network-load performance.
