EMSM:a Effective Multicast Streaming Mechanism in Wireless Mesh Network
Xiaoheng Deng · Journal of Chinese Computer Systems · 2012
Network coding is a method that promises to achieve high throughput for multicast streaming in wireless mesh network.However,it comes with two problem: delay and unfairness.We aim at solving this two problem.A effective multicast streaming mechanism in wireless mesh network(EMSM) is presented in this paper.EMSM control the unfairness baesd on the credit of node,and apperceives the decode capability of node,and selects destination set effectively.The unfairness of the node who has good channel is depressed.The system-wide delay is reduced by dual queue mechanism and native packets selecting mechanism in router.Simulation results show that the proposed scheme can achieve low delay,and the unfairness of tht good and bad channel is solving.
