| 摘 要： | 提出一种基于IEEE 802.11协议的MAC(media access control)层协同组播调度策略,利用正确接收数据的组内用户充当临时中继,根据地理位置信息选择优秀的转发节点来协同传输组播数据.分析了所提出的组播策略的中断概率和吞吐量性能,并给出了使用NS2(Network Simulator 2)工具的仿真方法.仿真结果表明,相比于原有的MAC层协议,该策略提升了组播的吞吐量,降低了组播用户的丢包率. |

| Abstract: | In this paper,we propose a MAC layer cooperative multicast strategy based on the IEEE 802.11 protocol,in which correctly received data can serve as a temporary relay if the user locates a right position.We analyze the outage probability and throughput performance of the proposed strategy,and present a simulation method in NS2.Simulation results show that the new strategy has a better throughput and lower packet loss performance compared to the original MAC protocol. |
