Two-level cache based streaming media scheduling algorithm for mobile network
Published 2007-01-01“…A novel caching system architecture for mobile streaming was proposed,which was named 2CMSA(two-level cache mobile streaming architecture).In this system,limitations for mobile streaming system such as small memory size in mobile terminal and low bandwidth in wireless access network were avoided.According to the 2CMSA,a scheduling algorithm of 2CMSS(two-level cache based mobile streaming scheduling) was designed;mathematical models were also achieved to analyze the performance of this scheduling algorithm.Simulation experiment proves that,comparing to the original mobile streaming system,by using the new two-level cache architecture and cache based scheduling algorithm,the network transmission cost and the client startup delay of the mobile streaming services can be decreased effectively.…”

APPLICATION OF HARMONIC FUNCTION’S THEORY IN TWO-DIMENSION OPTIMIZATION PROBLEM
Published 2018-01-01“…The mathematical models of many engineering problems can often come down to two-dimensional optimization problems,it has been one of the hot issues of seeking the high effective and precision optimizing method.The characteristics of harmonic function and Green theory were used to study the relations between the values of harmonic function and its boundary values,and demonstrate the non-locality of its extreme value.When the objective function of the optimization is harmonic function,the two-dimensional optimization can be simplified as a one-dimensional optimization on the boundary of its feasible region.At last,three examples were given to show the feasibility of the method here.The research ideas and the conclusions can be generalized to the solution of the three-dimensional optimization problems.…”
