EMMT: Multiflow wireless multicasting transmission for IEEE 802.11

Abstract

In Wireless multimedia services have a major applications of next generation wireless networks to the efficient utilization of network resources when a channel becomes saturated that time develop the number of concurrent multimedia flows to the network. How, In the flow scheduling and the channel aggregation policy are both the single-hop and multi-hop wireless networks with the motivation of the trade-off between the multiple flow transmission and limited channel resources. So to develop the number of performance and data flows are guaranteed increase in multimedia flows, it based on the dynamic states of wireless channels and the profiles of multimedia flows, we following that above two policies are fully utilize the performance gap to schedule concurrent flows for transmission in turn and aggregate multiple channels' residual capacities for useful flow transmissions. We then design a novel algorithm - efficient multi-flow multicast transmission (EMMT) - to apply the proposed policies to practical wireless multimedia multicast applications. So we can increase the data flows in multimedia in deferent path. Here we use ns2 simulations to evaluate the policies and the EMMT algorithm. This type of process is proved that the resource allocation of the new technology and also compared with Channel diversity transmission method. With the further development of quality of service schemes on relating user experience to QoS.
