Table 2 Performance evaluation of the extended RIR update control strategy w.r.t. the MAEC, MKWF, and oracle MAEC approach. MWF results are provided for better comparison. All results are averaged over all iSIR conditions in the considered meeting scenario. First and second ranked results are bold face and italicized, respectively (oracle results excluded)
