摘要

随着多媒体技术和移动设备的不断发展，向移动设备传输多媒体流的需求将成为无线网络的主要应用之一。但是，IEEE 802.11由于无法与多个接收方交换ack以及信号干扰、拥塞和终端隐藏问题的影响，不支持可靠的组播。它不适合在这种环境下进行实时多媒体传输。本文提出了一种新的可靠组播方案，采用三层方案来解决上述问题。仿真结果表明，采用该可靠方案的无线网络性能明显优于原有的802.11协议。在这种可靠的802.11环境下传输的数据包丢包率大大降低，并且在移动节点上，这种可靠的无线环境的吞吐量比原来的802.11协议表现得更好。

A new reliable multicast scheme for multimedia applications in wireless environment

With the constant development of multimedia technologies and mobile devices, the demand of transmitting multimedia streams to mobile devices will be one of the major applications in wireless networks. However, IEEE 802.11 does not support reliable multicast due to its inability to exchange ACKs with multiple recipients and the influence of signal interference, congestion and hidden terminal problems. It is not suitable for the real-time multimedia transmission in this environment. In this paper, we propose a new reliable multicast scheme to solve the above problems by using a three-layer scheme. Our simulation results show that the performance of the wireless network with this proposed reliable scheme is much better than the original 802.11 protocol. The loss rate of the packets transmitted in this reliable 802.11 environment decreased a lot and the throughput of this reliable wireless environment performed constantly well compared with the original 802.11 protocol for mobile nodes.
