Comparative analysis of QoMIFA and simple QoS

Abstract

This paper evaluates the performance of QoS-aware Mobile P Fast Authentication Protocol (QoMIFA) compared to the well-known Simple QoS signaling protocol (Simple QoS) via simulation studies modeled in the ns2. The evaluation comprises the investigation of network load impact on both protocols with respect to the time required to reserve resources, number of dropped packets per handoff and number of packets sent as best-effort after the handoff is completed and until resources are reserved. Our simulation results show that QoMIFA is capable of achieving fast and smooth handoffs in addition to its capability of reserving resources very quickly. QoMIFA is approximately 97.75 % and 73.92 % faster than Simple QoS with respect to the average time required to reserve resources on downlink and uplink, respectively. It drops 79.63 % less on downlink and 46.6 % less on uplink and results in 98.40 % less packets sent on downlink as best-effort. © Institute for Computer Science, Social-Informatics and Telecommunications Engineering 2009.
