ABSTRACT

This paper has proposed Hybrid QoS Routing Link State Update(LSU) Algorithm that has hada both advantage of LSU message control in periodic QoS routing LSU algorithm and QoS routingperformance in adaptive LSU algorithm. Hybrid LSU algorithm can adapt the threshold basednetwork traffic information and has the mechanism that calculate LSU message transmissionpriority using the flow of statistical request bandwidth and available bandwidth and determine thetransmission of the message according to update rate per a unit of time. We have evaluated theperformance of the proposed algorithm and the existing algorithms on MCI simulation networkusing the performance metric as the QoS routing blocking rate and the mean update rate per link, it thus appears that we have verified the performance of this algorithm that it can diminish to10% of the LSU message count.
