TRUST ASSISTED HANDOVER ALGORITHM FOR RELIABLE HANDOVER home network in trust relation higher priority. The THOA can perform well in achieving load balance when the ETS is made suitably large. Figure 5.6 Handover delay vs. Trust density [ p � 50% ] - 102 - A
TRUST ASSISTED HANDOVER ALGORITHM FOR RELIABLE HANDOVER Figure 5.7 Load balance factor vs. Trust density [ p � 50% ] It has been observed that the level of trust association between home network and foreign networks can have certain effect on handover delay if the MHOA is applied. Figure 5.9 shows that the handover delay grows from 1070ms to 1255ms, when the probability of no trust association (trust density equals 0.3) drops from 1 to 0 in the MHOA applied case. The results suggest that reducing the trust ambiguity in the AAA relationship between networks may improve handover performance in low trust density scenarios. In comparison, the same experiment was conducted using the THOA. Figure 5.8 shows the experimental results of applying the THOA. The THOA apparently mitigates the side effect of implementing the fine-grained AAA policies (e.g. a detailed classification of subscribers for authorisation) in home networks. - 103 - A
