摘要
介绍了无线自组网络中的分布式资源分配协议和IEEE802.11e协议,并对两种协议在提高网络的吞吐量和端到端的时延性能等方面做了分析比较,仿真结果表明在轻负载情况下,由于802.11e没有采用节点之间的握手联络信号,具有较低的时延;但由于竞争接入信道时缺乏协调控制,丢包率较高。在重负载情况下,分布式资源分配协议的性能指标均优于802.11e。
This paper introduces distributed resource allocation protocol and IEEE 802.11e in wireless auto-configuration network. The two protocols are compared upon promoting network delay and end-to-end delay. Simulation results show the characters of the two. With light load, 802.11e has low delay because it does not adopt liaison signal between nodes. But802.11e has a high packet loss ratio because of the lack of coordinate control in accessing the channel. With heavy load, distributed resource allocation protocol puts on a good performance against 802.11e.
