TRUST ASSISTED HANDOVER ALGORITHM FOR RELIABLE HANDOVER<br />

(b) Average network latency<br />

(c) Average packet loss<br />

Figure 5.12 Comparison of the THOA and the MHOA on QoS<br />

The simulation results shown <strong>in</strong> Sec. 5.6 demonstrate that the THOA can provide much<br />

more reliable handover than the MHOA <strong>in</strong> a multi-operator environment. The THOA<br />

can provide flexibility <strong>in</strong> balanc<strong>in</strong>g QoS and handover delay and thus improve<br />

performance output <strong>in</strong> handover. The proposed algorithm is especially suitable for the<br />

low trust density scenarios, where reliable handover is rarely provided us<strong>in</strong>g current<br />

handover approaches such as MHOA.<br />
