Wireless Traffic Monitoring

Easy to setup: no interaction with existing infrastructureProvide local and global status of network nodes at the same timeProvide good traces of 802.11 link-level operations

Captured InformationPhysical layer (Prism2 monitor header)RSSI (Received Signal Strength Indication, SQ (Signal Quality), Signal strength and Noise (in dBm)802.11 Link layerProtocol version, frame type(management, control and data), Duration for NAV(Network Allocation Vector) calculation, BSS Id, Source and Destination address, fragment, sequence numbersTCP/IP, application layer info also available

Wireless Monitoring Hidden Terminal Problem, LossesHidden Terminal ProblemDifficult for sniffers to detect all the wireless stations.Various losses are observed in sniffersFrame lossAP loss : Some APs are not correctly detected by some cards.Type loss : Control/Management types are not correctly detected by some cards.Loss variability Due to signal strength variability and card variability

Challenges of Wireless Monitoring Placement of SniffersProper placement of sniffers can improve terminal detection ability and reduce various losses in sniffers.Where to place sniffers?Too close to APs: incur signal saturations.Too far from APs: cause hidden terminals.How many sniffers to place?

Study to dateExtensive passive observations on loss and loss variabilityObserved hidden terminal problemsObserved frame loss, AP loss and Type lossObserved loss varies from 0% to 100%Active end-to-end delay experimentCauses of end-to-end delay in wireless network

MethodologyLocation: A.V. Williams Bldg, UMD.3 different WLANs (umd, cswireless, nist) 58 Access Points: 29 Cisco (umd), 12 Lucent (cswireless), 17 Prism2-based (nist)SniffersLinux OS 2.4.19Wireless card driver: orinoco_csCapturing tool: libpcap 0.7, ethereal 0.9.6Wireless cards used: Lucent Orinoco, Linksys, D-Link etc.

Passive Observations: Hidden Terminals and LossesHidden terminals: vary depending on cards used in sniffers and sniffer locations.Loss in sniffers Frame losses are calculated from 802.11 sequence numbers.From-AP and To-AP losses are noted separately.Findings:More To-AP losses are observed than From-AP. Most of To-AP losses are caused by a small number of wireless stations.Linksys cards cannot detect some APs correctly.Lucent cards cannot detect ACK/RTS/CTS frames.
