Abstract:
The coexistence between Bluetooth system and IEEE 802.11 frequency hopping spread spectrum(FHSS)equipment is analyzed. Based on the capacity formulae and system simulation, the inter-affection between these networks is compared. A fragment adaptive solution of packet payload length is presented, which can be used to improve the capacity reduction of IEEE 802.11 FHSS network. Analysis results show that the IEEE 802.11 WLAN standard with its inherent mechanism supports this fragment length adaptive algorithm. With the increasing of Bluetooth interfering networks, this adaptive solution can effectively relieve capacity decreasing of IEEE 802.11 FHSS network. The capacity analysis method and adaptive algorithm adopted in this paper can also be generalized into other FHSS networks.
对无线个域网应用环境下采用跳频方案的蓝牙网络和IEEE 802.11 FHSS网络之间的共存性问题进行了研究, 通过容量分析和系统仿真, 比较了它们的相互影响.在此基础上, 提出了采用包负荷长度分段自适应的方法来提高IEEE 802.11 FHSS网络的抗干扰性能, 并对所提方案进行了分析仿真.结果表明, IEEE 802.11 WLAN标准的内在机制能够支持本文提出的方法, 改善了抗干扰的鲁棒性, 并且随着蓝牙干扰网络数量的增加, 采用自适应方案的IEEE 802.11 FHSS网络的抗干扰性能明显增强
