Resource management mechanism | Compared strategies | Maximum Erlang capacity gain [Erlangs] | Maximum percentage on Erlang capacity gain [%] |
---|---|---|---|
Buffer for new data calls | E3 vs E4 | 5.15 (y \( {P}_{\mathrm{ft}\_\mathrm{d}}^{\left(\mathrm{S}\right)}=0 \), at the expense of a longer transmission delay) | 72.36 |
Spectrum adaptation | E2 vs E1 | 1.65 (and lower \( {P}_{\mathrm{ft}\_\mathrm{d}}^{\left(\mathrm{S}\right)} \) and transmission delay) | 43.1 |
Double preemptive and channel reservation | E5 vs E4 | 0.16 (the same \( {P}_{\mathrm{ft}\_\mathrm{d}}^{\left(\mathrm{S}\right)} \) and transmission delay) | 1.13 |
Selective interruption | E6 vs E1 {E7 vs E2} | − 0.03a {− 0.11a} (higher \( {P}_{\mathrm{ft}\_\mathrm{d}}^{\left(\mathrm{S}\right)} \) and similar transmission delay) | -0.43a {−1.37a} |
Buffer for interrupted data calls | E5 vs E7 | − 0.47a (\( {P}_{\mathrm{ft}\_\mathrm{d}}^{\left(\mathrm{S}\right)}=0 \) for E5 strategy. The transmission delay is the same for both, E5 and E7, strategies) | −7.23a |
