摘要:The interference between wireless communications may cause packet loss and bit error. There are multi-channels in wireless standards such as IEEE802.11b/g, the packet loss rate caused by interference between channels is different. Experiments are done to show the transition feature between channels in IEEE 802.11b/g standard. The results show that the traffic throughput depends on the radio frequencies that the channels use, and the feature is different between TCP and UDP. The performance of TCP is further low on the interference environments, and there should be more suitable translation method in wireless network. Based on the results of experiments, a channel assignment algorithm is proposed to reuse the wireless space. Analyses show that the algorithm is simpler and can get similar performance improving in IEEE802.11-based Wireless mesh network.
