Purpose • 802.11, 802.11b and 802.11g get interference from other non-802.11 radio devices. • CCA Idle Time Histogram of Medium Sensing Time Histogram is useful to optimize frame length. • Evaluationsof perfomance shows the effectiveness of optimized frame length on the interference environment. Shoji Sakurai, Mitsubishi Electric
Evaluation environmentwith Bluetooth • Use 802.11g with 9 piconets of Bluetooth • Upload data from Station to Server in UDP Bluetooth piconet 1 Server ST AP UDP Bluetooth piconet 2 : Bluetooth piconet 9 2 thin walls 0.5m 30m Shoji Sakurai, Mitsubishi Electric
Evaluation result 802.11g thoroughput with Bluetooth interference(Kbps) Shoji Sakurai, Mitsubishi Electric
802.11g throuput with Bluetooth for different frame length Shoji Sakurai, Mitsubishi Electric
802.11g throuput for different number of Bluetooth piconets Shoji Sakurai, Mitsubishi Electric
Evaluation environmentwith Microwave • Use 802.11g with a microwave • Upload data from Station to Server in UDP Server ST AP UDP Microwave 2m /5m 2 thin walls 30m Shoji Sakurai, Mitsubishi Electric
Evaluation result with Microwave 802.11g thoroughput with microwave interference(Kbps) Shoji Sakurai, Mitsubishi Electric
802.11g throuput with Microwave for different frame length Shoji Sakurai, Mitsubishi Electric
Conclusions • Optimized frame length improves throughput under heavy interference. • Effectiveness depends on degree of interference and unsuitable frame length falls the throughput. • CCA Idle Time Histogram of Medium Sensing Time Histogram gives direct information to estimate the optimized frame length.
