Vertical Handover Decision Algorithm Using Multicriteria Metrics in Heterogeneous Wireless Network
Table 1
Comparison of vertical handover decision algorithms.
| | Heuristic | Advantages | Disadvantages |
| RSS-based:
Bing et al. [4]
Eshanta et al. [3] | Low complexity | Low reliability and no user consideration |
| Multicriteria:
Alkhawlani et al. [21] | Low handover failure | No support on fuzzy decision |
| Context-aware:
Zekri et al. [1]
Hasswa et al. [22] | High throughput | Additional delay on handover information gathering process |
| Cost function:
Calvagna and Modica [11]
Ong and Khan [23] | High user satisfaction | High complexity |
| Fuzzy logic:
Ribeiro [14]
Pahlavan et al. [24] | High reliability | High complexity |
