Compared with the Monte Carlo simulation results, we can conclude that the commonly used GQA approach cannot precisely predict the system performance.
The error rate obtained by the commonly used GQA method is not coincident with the precise BER, as expected.
PreReservationNotify: Used by border GQA, RQA and MQA to inform neighboring ARs to make prereservation .
MGroupJoin: GQA, RQA and MQA request to join multicast group .
The R-REV reservation model is used in this situation through the intervention of three QoS agents MQA, RQA and GQA.
On receipt of RoamNotify message new RQA converts the P-REV path to R-REV and GQA transmits the PATH messages to MNs new location through new RQA.
With this multiple processing capability, the GQA
, available commercially through Servomex, Norwood, Mass.
The Xenith 9000 GQA is designed to analyze most of the possible volatile organic compounds (VOCs) and hazardous air pollutants at emissions points in industries that emit solvents and other gas components through venting systems.
The heart of the Xenith 9000 GQA consists of up to eight micro gas chromatography systems that allow parallel processing of several selectable process streams.
The Xenith 9000 GQA is being marketed by Servomex, Norwood, Mass.
Other staff members are now working towards gaining the GQA NVQ level 3 qualifications - again with Barnsley College.
