To solve the problems such as how to choose the clients with high performance as voluntary servers to provide video services to other users and how to ensure the stability of voluntary servers in the hybrid video grid, we propose a new algorithm for selecting voluntary server based on stability degree. Selection process of voluntary sever was simulated and emulated by using simulation software AnyLogic at micro level. The results indicated that the voluntary servers selected by the algorithm have better stability compared with them that selected by the random selection algorithm; therefore, the system stability and service capacity is improved after using the voluntary server selection algorithm. This study provides a theoretical basis for the practical application system.
