Abstract: In the mobile application layer multicast communication,the streaming media service satisfaction may be reduced because of too many users in the hot place,while the not hot places may produce resources waste phenomenon,which leads the whole system performance degradation.This paper proposed an adaptive load balancing mechanism based mobile terminal active feedback.ALBM-MTAF uses some network-related performance metrics to simulate the streaming media service satisfaction,which is obtained by mobile terminal.Then through the mobile user’s active feedback to adaptively adjust,system switches the child nodes in the not hot places to the places having the better SMSS,so as to realize the load balance of the whole system.The simulation experiment shows that the mechanism has good load balancing effect,and can guarantee the quality of communication.
