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 |
